On July 19, 2010, Rackspace led the announcement of OpenStack, with a goal of creating an open source cloud software solution for use on industry-standard hardware.  The initial releases contemplate solutions for both cloud compute and object storage.  While these are the first two releases, they are separate offerings.  Remember, cloud storage is not just the storage target for cloud computing, it is one potential storage target for cloud computing, and is in and of itself a stand alone cloud offering of programmable storage.

Now, I have purposely used a term from the clothing industry, "off the rack", to spend a moment looking at a framework for evaluating the opportunities this may present.  With dress shirts, you can buy off the rack, semi custom, or custom, each with a unique value proposition based on fit, choice and cost.   Interestingly enough, this may be a good lens through which to consider the possibilities of OpenStack, and in particular, OpenStack Object Storage.

Rackspace has made no secret of its motivations for leading this initiative, and its desire to focus on "fanatical" service as it's key differentiator versus the fundamental technology on which the service is based.  Fair enough, and so the question becomes, is the rapidly emerging and immature cloud marketplace already "mature" enough to seek homeostasis?  (Homeostasis is the property of a system, either open or closed, that regulates its internal environment and tends to maintain a stable, constant condition.)  Have enough models and innovations, from startups, academia, open source movements and large tech companies, been tested in the marketplace to the extent that we can already race to the common denominator?  Perhaps now is a good time to start, as long as you are willing to acknowledge that the desired results are a good ways off.

Before we jump off into "Off the Rack" software, a quick look back at open source is helpful.  For more reading on the open source software industry a good introduction is The Cathedral and the Bazaar. Six things are particularly interesting: 

1. An open source alternative can emerge as a follow on to a successful commercial technology and can become pervasive versus the commercial offerings it succeeded (LINUX versus UNIX is the reference case here).
   
2. A second result of this approach can also end up with a big success, although in more of a niche than a pervasive replace for the earlier commercial offerings (MySQL versus Oracle, IBM and Microsoft in the relational data base space).  
   
3. An open source effort can also emerge earlier in a technology cycle and come of age as a pervasive solution (Apache Web Server comes to mind here).
   
4. Open source generally requires very careful cultivation of the community of developers, with active interest by academia (and partnering with NASA is part of the formula here).  Commercially sponsored open source efforts are becoming more common, although it as of yet has not been proven as the typical "breeding ground" for most great open source successes.  Eucalyptus, with its roots at University of California Santa Barbara, seems to be a more traditional route.
   
5. Open source is not necessarily reflective of rapid commercial opportunities for success.  Eucalyptus is obviously beginning to maneuver towards a repeat of the commercialization model.  OpenStack is taking the approach most favored by other open source successes like Apache.  A couple of good reads here are this article from BusinessWeek and this. See also Derrick Harris' post over at GigaOm.
   
6. There are also hundreds of thousands of open source projects that had mixed success or languished altogether. A quick look at  SourceForge (an open source project hosting site) shows nearly a quarter million hosted projects. How many of these have languished or had little impact on the market.
   

So, the first issue is that there will exist for some time to come a real question as to the adoption potential of OpenStack.   I believe that adoption is driven by applicability to need.  In a moment we will address a serious issue which OpenStack Object Storage must overcome to be successful, at best, and at worst, will confine it to a niche market.  My views are very much directed at the Object Storage offering, versus the compute offering, which I believe exists in a different space and as a different type of solution.  With this backdrop, let's have a look at the cloud storage marketplace today, and use the analogy of off the rack, semi custom and custom:

• Off the Rack:  implement as is, one size fits all, each with unique approaches for performance, scalability, bit integrity, may or may not provide geo services.
• Semi Custom:  Select from storage types (DAS, SAN, NAS, JBOD), shared or distributed file systems and object systems, mix and match storage for different SLA and cost/usage patterns on the same infrastructure, multiple APIs, meta data and catalog abstracted from storage layer, geo services.
• Custom:  Generally a service only offering and not available as deployable infrastructure, specifics will vary widely based on service provider offering strategy.
  

Infrastructure	Type	Comments
Eucalyptus	Off the Rack	Limited S3 APIs
OpenStack	Off the Rack	CloudFiles APIs
Scality	Off the Rack	S3 APIs
Mezeo	Semi Custom	Mezeo ReST APIs and S3 APIs
NetApp	Off the Rack	Bycast APIs, NetApp storage
EMC Atmos	Off the Rack	Atmos ReST APIs, EMC storage
Service	Type	Comments
Amazon S3	Custom	S3 APIs
Microsoft Azure	Custom	Windows centric
Rackspace	Off the Rack	Is the basis for OpenStack
Nirvanix	Custom	SOAP APIs, multi node
Google	Custom	Offers S3 APIs
AT&T Synaptic	Off the Rack	Based on EMC Atmos
OpSource, SoftLayer, Layered Tech and others	Custom	Based on Mezeo

As you can see from the summary above, there exist as many views of what constitutes either a cloud storage service or a desirable cloud storage deployable infrastructure as there are service providers and vendors.  Note that a semi custom infrastructure results in a "custom" service as implemented.  "Off the rack" results in very similar services by those who utilize the same infrastructure unless they make their own major additions.  Any offering can be differentiated by service, and the degree and quality of service is critical to customer satisfaction and plays a strong role in value creation.

The OpenStack announcement as it regards Object Store and its approach to cloud storage seems to view cloud storage infrastructure as highly akin to an operating system (or at least a "hypervisor") and more similar to a selection of LINUX or Windows than that of an application or middleware layer.  While I agree that cloud compute is very close to this model, cloud storage is a service oriented architecture, with programmability for new applications that can tolerate Internet latency because of Web Services (like ReST APIs). The industry constantly overlooks this key point as it is consumed with the low cost, pay for use and thin provisioning capabilities of this storage tier.  Solutions for thin provisioning and low cost have been available far longer than cloud storage. Further, pay for use is more of a business decision than a technology. 

In the earliest days of cloud storage, there existed initial confusion that cloud storage was defined by cost, scalability, pay for use, and thin provisioning only and not programmable access (usually via ReST APIs).  ParaScale paid a huge price for not understanding that cloud storage requires Web services (like ReST API) access.  Now, with OpenStack Object Store, we see a follow on case of this same perspective, but with basic APIs for Put, Get and List.   Yes, it provides for Internet access via ReST APIs, but the focus continues to be primarily cost based versus new application enablement based.  It could be argued that the open source approach will provide for the appropriate additions of "advanced services" to be added.  However, even the use of the platform by NASA is more focused on cost of storage than on advanced functionality because NASA stores much more data than almost any institution or enterprise in the world.

I think Savio Rodrigues states this view very well in his post:

"Select products based on business needs, not license alone: It's also interesting to note that very few enterprises are in NASA's position with regards to size of IT investment and skills in-house. While NASA engineers were ready and willing to contribute new features into the Eucalyptus open source community, few companies have the skills or governance to consider allowing their developers to contribute to open source projects.  Summary trend number 7 from the 2010 Eclipse survey results highlighted this issue.

To suggest that NASA's buying or IT decision making patterns represents much more than the top 1 percent of IT buyers would be a stretch."

The overwhelming majority of enterprises would rather pay a vendor to deliver, maintain, support and enhance their private cloud software infrastructure than place that burden on internal IT staff. Whether the enterprise is paying for a closed source commercial product, a commercial product based on an open core product, or a subscription to an open source product, the product selection decision will be made based on business requirements much broader than 'is the product open source or not?' "

Keep in mind that cloud storage is a stand alone service associated with application delivery over the Internet and also associated with low cost, pay for use, scalable storage resources.  Social media applications and many Web based applications exploit these capabilities; for example publishing a file to a URL and significant tagging of files.

This view of cloud storage as nothing more than cost and volume-based ignores its extraordinary importance as a service-oriented architecture for new application enablement.  I believe both views are equally important and need to be equally served.  Will OpenStack, with its pervasive cost focus, be able to drive its community to this additional view of needed contributions of advanced services for cloud storage?  Lydia Leong of Gartner Group provides an interesting view of the open source community issues associated with this in her post:

"At the same time, open sourcing is not necessarily a way to software success. Rackspace has a whole host of new challenges that it will have to meet. First, it must ensure that the roadmap of the new project aligns sufficiently with its own needs, since it has decided that it will use the project's public codebase for its own service. Second, it now has to manage and just as importantly, lead, an open-source community, getting useful commits from outside contributors and managing the commit process. (Rackspace and NASA have formed a board for governance of the project, on which they have multiple seats but are in the minority.) Third, as with all such things, there are potential code-quality issues, the impact of which become significantly magnified when running operations at massive scale."

One last comment on this business of vendor lock in and cloud storage APIs (another focus of the OpenStack announcement).  I would submit that while a specific set of APIs has the potential to create vendor lock in, this is a much smaller problem than what is experienced in other technologies.  If you are really worried about it, you probably have never actually written a ReST API call.  It is written in many languages, and we have seen cases where applications that run on S3 run unchanged on Mezeo.  Others need very minor modifications, and still others are excited to take advantage of some of the unique Mezeo services.  It just is not a problem, and this is much more related to FUD (fear, uncertainty and doubt) and marketing zealotry than it is associated with technological reality.  The APIs of choice will shake out, and it is far to early to say if it will be S3, OpenStack, CDMI or a combination of all of these, and others, as yet unforeseen.  (At Mezeo, we have never believed there will be one winner, and instead focused on architecture to enable easy and effective delivery of whichever APIs stand the test of time.)

The interesting view that seems to be missing here is that marketplace competition by service providers already serves to drive down the price of cloud storage, so a commoditized stack embraced by most is unlikely to yield extraordinary incremental savings.  At the same time, while the competitive market conspires to drive cloud storage costs ever lower, the need to differentiate, and deliver solutions as well as a programmable storage to enable multiple new and exciting types of applications will rapidly replace the pure cost and scale focus of current cloud storage offerings.  Sometimes, the "new" application is simply enabling it in the cloud, to produce the same result at a lower cost!  This requires significant cloud storage functionality in order to make this easy and productive.  Amazon continues to prove this with their many additions and capabilities which differentiate their service.  Mezeo sees much the same view on the part of our customers.  The focus is on what cloud storage can do, what problems will it solve, what business opportunities does it create, what new applications can it enable and all of these views assume it will be competitively priced.

Cloud storage represents significant opportunities for institutions, the enterprise (see my recent post on the business case for enterprise cloud storage) and for the IT service provider.  Cloud storage is substantially different from cloud compute, and requires that you understand this difference in order to effectively evaluate the impact of this announcement, as well as your next steps.

Cloud Storage Strategy interviewed Gladinet co-founder Jerry Huang on cloud desktops, cloud gateways, and his company's business model. 

[NOTE: Gladinet is a customer of Mezeo Software.]

Cloud storage is already showing signs of Phase Two (see our post on the cloud storage maturity model), as a new set of solutions arrive in the marketplace.  These solutions are referred to as cloud gateways, on ramps, cloud clients, edge devices and other exotic names. 

For ease of discussion, lets use "cloud client" to describe a solution that is on a single user device (workstation, PDA, Tablet) and "cloud gateway" or just "gateway" for a solution that is delivered on a server or router for many users.  Whether they are a client or a gateway, some store a "blob" of data, and some store "chunks" of data that are parts of the original object.  Others store the actual object.  What's the difference and is it important? Should you consider it in your cloud gateway use plans?

What is a blob?  A blob can start as either a single object or a collection of objects, for example, all of the files on a single server, or a VM image.  Then, you do something to it in the client/gateway device that requires it to be brought back through the original client/gateway to be returned to a useful state.  Examples include de-duplication and compression followed by encryption prior to transmission of the object to the cloud (I call this D/C/E).  The result is a "blob" of data, an object that is minimized in size, and must be retrieved by the application that created it in order to be useful again. 

A chunk is part of an object, and the original object must be re-assembled by the gateway that parsed it in the first place. Some gateways store blobs.  Some store the object in chunks.  Finally, some store the actual object with its original file type, intact.  These may be workstation clients, or interface solutions that allow for a CIFS or iSCSI (today, TwinStrata is an example of the iSCSI capability) attached device to store in the cloud.  There are trade-offs and advantages associated with each approach, and your cloud storage use case and objective must be carefully analyzed in order to determine the applicability of the gateway to your business requirement.

Now, let's consider D/C/E.  This provides savings in addition to the savings associated with cloud storage.  D and C gives you a small object size, so your bandwidth cost is lower, and your overall storage cost is lower.  When there is a change to the stored objects, chunks allow you to send only the changed part of the object, reducing bandwidth and potentially improving performance.  Encrypting, or chunking, or both, may improve security and relieve you of the costs and management associated with other security approaches.

So, blobs and chunks sound pretty good, providing better security and lower costs.  What's the catch?  First, storage clouds are great places to provide anytime and anywhere access to your data, from multiple devices.  If you have to go back to a gateway to get the original version of the object, that flexibility may be very limited or non-existent.  Clouds are also a great place for sharing and collaboration, which is not in play if the object in the cloud is not in a useful form.  Finally, vendors are not giving gateway solutions away - we must ask what they cost, and are they worth it?

As usual, the answer is, it depends.  What services can I get from the cloud? And what services can I get from the gateway?

An example that is getting a lot of attention is file server replacement, or even better, file server displacement.  I get less excited about replacing a file server with another server that is a policy driven cache, because I still have this layer of technology in place.  However, if you can displace most of your file servers, then the potential for significant cost savings become obvious.  

I tend to look at single user clients as very interesting on ramps to the cloud.  A client, using some modest amount of workstation storage as a cache, can deliver most of the benefits of a file server.  Companies like Gladinet, SMEStorage, GoodReader, Mezeo and others have very interesting cloud clients.  You will still need a few file servers if you need to provide a place for very large files.  Interestingly enough, those very large files are often rich media (like training videos), and streaming them to a reader on the client from the cloud is often good enough.  Another cloud client capability we expect to see will allow the end-user to store files and move them across multiple storage providers - from private to public and vice-versa, for example.  This functionality could also be in a server-based gateway.

Another cloud client capability might include giving encryption capability to the end user, and let them decide if they want to encrypt the file themselves.   Or, use a cloud that provides user selectable encryption.  Give your end users or customers the power of choice, the freedom of access anytime and anywhere, the ability to get the amount of storage they need when they need it (what Gartner calls "reservationless", and kudos for them, great term).  Don't tie users to a "home base" gateway that does not store their object in it's original format, or at least give them a choice.  All that being said, we are seeing that some mix of clients for file server displacement, and file server replacement gateways may ultimately be the appropriate solution.  

Backup and archive is a different story, and here a gateway can make a lot of sense.  First, there is quite a bit of local housekeeping associated with these solutions, and the solution can decide if utilizing the cloud for some or all of the files makes sense. Speed of restore is a major consideration for a backup, and may drive local versus cloud based storage solutions.  Further, the need for a disaster recovery site, or to archive, can often be a cloud use case.  Companies like Zmanda and CommVault are very active in cloud based backup solutions.  What if you have applications that do not speak REST APIs, like a legacy backup solution?  There are gateways that can attach these legacy applications to the cloud, for example, TwinStrata.

Special purpose gateways can also solve an immediate problem.  Blue Thread offers a cloud storage interface for SharePoint.  The marketplace is rapidly developing a portfolio of cloud storage gateways and clients, as well as backup and archive solutions and all have their own unique perspective on cloud use.  Examples include StorSimple, Cirtas, Gladinet (who also makes clients), and EntropySoft.  Venture capital companies are deploying significant capital for these sorts of solutions.  Each of these solution providers sees a clear path to adding significant value to cloud storage solution delivery.

Cloud storage requires significant use case consideration to evaluate the functionality required, both in the cloud and in the gateway or client, and where the application or user can best exploit the functionality.  After all, cloud storage is also about empowering the end user with the storage they need, when they need it, at a favorable price, and providing advanced functionality, like publishing and sharing.

At Mezeo, we have both a deployable cloud infrastructure, and clients.  That causes us to look at where the best place to put the functionality is.  That creates a slightly different perspective, and we think it creates very useful products.  On the other hand, nothing gets us more excited than the thought of more solutions that drive cloud storage adoption and usefulness.  For this reason, we are rolling out a new marketing and certification program, Mezeo Ready™. 

With Mezeo Ready™, service provider public storage clouds can easily identify their offering as being "Ready" for use by Mezeo Ready™ clients or gateways, and backup and archive solutions.  Users of these products can pick one of many trusted service providers hosting Mezeo Ready™ cloud storage solutions.  This cloud storage on ramp and cloud storage provider "ecosystem" ultimately delivers valuable solutions to customers and is a big part of Mezeo's vision for the cloud storage market.

So, more to come on Mezeo Ready™, we are nearing the official announcement of the program, and will extend it to storage providers and file system providers who work with Mezeo to deliver storage clouds, both private and public.  Other solutions, like billing and provisioning systems will also be in the Mezeo Ready™ program.  The changes the cloud is delivering are new and useful, and deliver real value to the institutions and businesses that are embracing them.  The ecosystem is critical to the value delivery chain, and key to providing unique, desirable solutions.

A recent report by Forrester's Andrew Reichman titled Business Users Are Not Ready For Cloud Storage: Current And Planned Adoption Of Storage-As-A-Service Is Minimal For Now paints a picture for cloud storage adoption, that at first blush, is not encouraging.

He states:

In Forrester's Enterprise And SMB Hardware Survey, North America And Europe, Q3 2009 survey, we asked businesses about their interest in "hosted storage capacity" offerings. Interest was minimal at best. Forty-three percent of all respondents said that they were simply not interested, and another 43% said that they were interested but had no plans to move forward.

While it could be argued that as a cloud storage supplier, I am necessarily bullish about the ultimate prospects, I believe the data is actually quite good and clearly represents what we are experiencing in the marketplace.  Now, Mezeo is engaged with many service providers, as well as the early adopters in the enterprise space as they begin their evaluations.

When I look at enterprise cloud-storage adoption based on Everett Rogers' diffusion curve I see a pretty clear view of the typical market place approach to adoption of disruptive technologies:    

For new, emerging, and potentially disruptive technologies, we should look for what the next practices are, i.e. the practices of the innovators and early adopters. The survey reflects the typical technology adoption cycle and re enforces what we are experiencing in the market place.

11% of companies are taking the plunge - these are the early adopters and innovators.  The early majority (43%) is interested, and watching.  The late majority is not in the game, yet.

So we are on track. And to prove it, let's look at one of these enterprise-level innovators: General Electric.

According to IBM storage expert Tony Pearson, GE has implemented cloud-based backups and archive for GE Corp, NBC Universal and GE Asset Management divisions running at only 32 cents per GB/month, representing a 40-60 percent savings over their previous methods. This includes backups of their external Web sites, archives of their digital and production assets, RMAN backups including development/staging databases. They plan to add out-of-region compliance archive in 2010. They also plan to monetize their intellectual property by offering "CloudStorage Manager" as a software offering for others.

1. Security will continue to be a big issue for the cloud, and, unfortunately, there will be at least one event this next year that is disruptive to Cloud Storage adoption, be it data loss or unauthorized data access.  Security will be an even more important point of evaluation for the use of specific Cloud Storage service offerings. The “trusted service provider“  becomes a requirement when selecting a cloud offering.
   
   
2. Cloud Storage will be characterized by a single word, “more”!  More adoption, more cloud storage offerings by more IT service providers, more variation in cloud capabilities, and more worries and concerns about the cloud.
   
   
3. The intersection of enhanced mobile devices with better wireless bandwidth will be combined with Cloud Storage to create exciting new work/life blended digital life applications. The user experience is of paramount importance.
   
   
4. Cloud Storage will see extraordinary adoption as a solution for backup, archiving and for policy-based georeplication for disaster recovery.

If you're accessing your data anytime, anywhere in the cloud, location shouldn't matter, right?

As it turns out, it does. There are several reasons why it matters where your cloud storage is located:

Legal & Regulatory Policy: How do companies ensure they are archiving and protecting business data to comply with  electronic data laws? According to BCS for example, no matter what data storage and security strategy an organization uses, IT decision makers should consider these six key questions:

1. Will content be stored and remain unaltered over the required retention time frame?
2. How will this technology stay updated to ensure long-term availability of records?
3. Does this technology enable the organization to retrieve data quickly enough to respond to a legal request within the stipulated deadline?
4. Can this technology grow with the business and meet regulatory requirements?
5. Can this technology be used with other content generating applications?
6. How will this data storage architecture address litigation and discovery challenges?

Add to this the effect of country and international compliance regimes and you understand why companies need to determine which data storage regulations affect them and require compliance.  Since the cloud is so new, I can safely wager that the data storage laws of most countries will not yet have a statute for the cloud. Thus, physical data storage laws will still apply.  So your cloud storage may have to be located in-country. This is possible through geo-location and geo-replication.

Performance: To reduce network latency, cloud storage and the applications that access it should be as close together as possible, even in the cloud, and they need to be close to the end-user.  Thus New York-based users who use NY-based applications should have their storage in a cloud in the NY area as well. 

Backup & Replication: Cloud-based backup and recovery makes sense as well. Having multiple instances of your data replicated by geography is a key function for distributed datacenter replication, and shows potential for rapid growth. 

So, at Mezeo, we see three ways to think about cloud storage and geographic options and how to improve the distribution of data across geographically distributed data networks:

Geo-Location: Locating stored objects close to where they will be used for. Faster access via the closest cloud storage instance using data center peering (this also allows you to define where you store your data/objects).

Geo-Replication: Replication through policies, with uninterrupted access to content.

Single Namespace: Providing a single means of access to stored objects regardless of where the objects are located.
 
Geographic placement supports creation of an object in a specific cloud storage instance.  At Mezeo, our replication policy allows for the specification of the locations of the replicants.  For example, the policy indicates "create the object in New York, LA, and Houston."  If an object is created in New York, it will be replicated to LA and Houston.  If it created in Houston, it will be replicated in New York and LA.

Some storage vendors support replication as a component of their disaster recovery recommendations.  If your selected storage vendor offers this option, then the storage solution could ensure there are at least two copies of every object in every instance of Mezeo's cloud storage.  Recovery in the case of disaster with this approach would be handled by the storage vendor's solution. 

By considering a combination of replication provided by storage vendors and replication provided by Mezeo, a service provider could offer a highly differentiated service.  Your customers would be assured of recovery in the case of any possible failure, from a single disk failure to a catastrophic data center loss.  Mezeo works with our service providers to determine the benefits of various replication options and the impact as you design your SLA level(s).

Policies are assigned in the onboarding/provisioning process and may be updated if requirements change.  There are also special situations for policy updates, such as if a particular data center has a catastrophic outage, the policies associated with replication to the Mezeo instance in that data center can be modified.

CloudStorageStrategy.com welcomes OpSource CEO Treb Ryan for an in-depth interview on cloud computing, from the perspective of the service provider.

NOTE: OpSource is a customer of Mezeo Software, the underwriter of this blog.

What are the opportunities you see in the cloud computing space, both for OpSource and your customers, and what impact has the downturn had on this?

It's interesting, but when people talk about cloud computing, they immediately go to the downturn and pricing - and cost being the big driver.  There's no question that cloud computing is cost effective, and it's accelerating adoption many times over, but what we're really seeing is something much more fundamental - a generation of users who are entering the workforce who've been using cloud computing all along; they've grown up on the Internet, and their interface to technology has always been through the Internet. 

As a result, this "Cloud Generation" has clear expectations of how technology should work:

1) it should be immediately available,
2) you do a search and get going,
3) it should be very flexible,
4) you should have ubiquitous access - anytime, anywhere,
5) sharing and collaboration - the expectation to collaborate and share anything they are working on.

This is not a generation which distinguishes between work data and home data - like my generation did. They've grown up with the concept of APIs and communities that grow around them; for instance, we see programmers who have grown up with Google and Facebook APIs, and now they expect that kind of thing in their work applications as well. So they're coming into the workforce and driving change in the workplace. They see technologies like client-server applications or hard-coded storage arrays pretty much the same way my generation saw green screens, mainframes, and mini-computers - as dated, inflexible, technology - hard to use, without nearly the power of cloud-based systems. So they have the day-to-day experience of the "consumer cloud" which they're now driving into business applications as well. 

To the Cloud Generation of programmers this means anything they can interact with on the Cloud they can program to through APIs. The idea of infrastructure being an item that can be addressed as part of the application, instead of something the application lays on top of, is a radical concept.  It has allowed not only for innovative applications, but also for true elastic computing making the Cloud environment even more flexible.



Great Cloud offerings have great communities around them. This is the aspect of Cloud computing that is so often missed - and even scoffed at - by the IT folks who think it's all about virtualization. One of the biggest gripes about Cloud computing is that support is done by the Community and not the vendor. While most will agree that far more proactive vendor support is necessary for Cloud computing, Community support is just as critical. For questions of configuration and usage tricks, the Community is a far better source of information than some call center employee with limited access. Often the Community devises more innovative solutions than the vendor ever could. And in addition to support, the Community can create third-party add-ins that make the Cloud even more useful.

The downturn has accelerated adoption from the top down as well.

We're seeing executives who have become enamored with this idea of the cloud - because of the ability to turn capital expenditures into operational expenses - and are pushing cloud computing into their organizations.  The CEO of one of our customers went so far as to tell his technical people - "now can you finally start using the cloud so I can get the board off my back?"

So, for different reasons, we have both top-down and grass-roots support for cloud-based applications, which makes this very interesting to say the least.

Which customer segments do you see leading the way in adoption?

Obviously, our traditional focus has been on ISVs and start-ups coming into Software-as-a-Service, business applications in the cloud, and we're seeing continued adoption of cloud infrastructure by those segments, but what has been interesting is that now that we offer the ability for any company to buy and use cloud infrastructure for any type of application, we're seeing a much broader spread of usage and adoption. Beyond the enterprise we also see widespread adoption by systems integrators, consultants, and VARs - upto 40% of our customer base - all without us targeting that segment at all.

How does OpSource differentiate its cloud offerings from other service providers?

We offer the best of the public cloud, combined with enterpise security and compliance, performance guarantees, and enterprise controls.

For instance, we offer:

• easy online sign-up & purchase with infrastructure provisioning in minutes
• pay by the hour and only for what you use, with no commitment (or purchase a monthly plan for a discount)
• a rich online community to share and collaborate with peers; get third party add-ins, images and configurations
• a web interface plus complete set of APIs

On the straight cloud, we provide a lot of the more robust, enterprise tools than you see from more consumer-based providers like Amazon, for example.

We focus on three different areas:

1) Security and Compliance: we provide a much more secure environment, because Opsource provides every customer with a Virtual Private Cloud within the public Cloud, allowing them to determine their own degree of public Internet connectivity. We also provide:

• Unique customizable security for firewalls
• VPN administration of all servers
• Unique username/password for each administrator
• Audit logs of all environmental changes
• SAS 70 audited
• 100% uptime SLA

2) Performance: we offer a multi-tier architecture with guaranteed latency in-between systems, sub-millisecond access time, industry standard technology, like VMware, instead of open-source, because that's where enterprise is comfortable.  Our 24/7 suppot also makes a diffence.

3) Control: today's cloud environment are single user environments, one user name and password, which is fine for individuals, but not so useful for the enterprise. We offer the ability to provision multiple users, do things like cross departmental billing, execute policy based control - which user can do what - and finally link all that back though an API to your existing management systems. So you can control how your users use the cloud same as you do your corporate datacenter.

So do you see any links into these large companies where they need to use ITIL for systems management?

Absolutely. OpSource has always focused on compliance as a major issue for our SaaS customers, eveything from SAS 70, PCI to European Safe Harbor, and even industry-specific ones like HIPAA, or government-specific certification, but in the cloud, we think about sophisticated  management techniques like federated authority and single sign-ons, and things like ITIL - while it's still in its infancy, it's shocking that most providers don't even have the ability to give their customers the critical capability to have more than one person manage the cloud for them - because they have a single user accounts. So while you can institute more sophisticated IT governance regimes like ITIL with the OpSource cloud, we give IT the capability to manage who does what, and track who did what, even if they aren't ready for something like ITIL.

So IT gets to do their own provisioning?   
  
Yes. So you want to know who provisioned what, how much it costs, and we give them that visibility instantly across their entire user community.  That way there are no surprises or charges they aren't aware of. It sort of reminds me of the controls I had to put in to alert me to my daughter's texting costs - so I'm aware of the charges before they get out of hand! I just blogged about this issue.

That's why you say that OpSource is what Amazon wants to be when it grows up... 

Absolutely.

And that's how you respond to cloud critics - the ones that say that the Cloud is not yet ready for the enterprise.

There are large parts of the cloud that are not yet ready for the enterprise. The cloud is still young, and it would be like asking that first 286 PC to run all of your corporate financials. However, a lot of these issues around enterprise adoption like security and compliance have been addressed, and are being taken care of, so as the cloud becomes more robust, we'll see increased adoption. We're seeing enterprise-level capabilities come to market that did not even exist six months ago.

We have just signed a partnership agreement under which OpSource will resell Gomez's Web performance management solution to our enterprise customers as well as use it to validate and monitor our own cloud performance service level agreements (SLAs). Through this partnership, we'll bring powerful performance monitoring to cloud computing, making it easier and more compelling than ever for enterprises to justify bringing their applications to the cloud.

Do you see infrastructure elements like storage growing now?

For true, full use of the cloud, we have to have the ability to access storage, go though the APIs to get to it, and give our customers a range of storage solutions, including cloud storage based on the specific application or need. We're giving our customers the widest range of choices.

What about agile programming? I heard you use agile methods to improve the customer experience.

Agile programming methods have helped us with not only development, but compliance and security as well. We talk to our customers to see how they are using our cloud offerings though our community, and we learn what's important to them.

We also test our offerings by having two programmers work on the same keyboard - literally  - one with the user story - so they can make sure that the customer is getting the exact functionality they need.

It's agile customer service.

Can you tell us a bit about your enthusiasm for composite applications (corporate mashups) and how they help your platform?

Of all the phenomenon in the cloud, we see the need for anytime-anywhere access and the idea that anything I can interact with I should also be able to program to.  So when Facebook enthusiasts start working in the enteprise, they bring their enthusiasm for integration as well.

So we see things in the cloud like direct access to the infrastructure as part of the application, which allows for all sorts of flexibility and robust usage.

We see real-time reporting applications of every kind you can imagine.  I myself am addicted to checking on everything that's coming out of our billing and customer systems tied into our Salesforce tabs.  So I'm always checking on the business in real-time via my iPhone.

I say this a lot, but integrating SaaS is a huge issue for today's enterprise. OpSource Connect can help SaaS companies -- of any size -- overcome integration hurdles and break out of the SaaS-only box. This speeds up adoption of SaaS in larger enterprise environments, opening the door for on-demand companies to cultivate business with large systems integrators. Plus, I'd say we're the only company providing Web operations from the ground up, addressing operational infrastructure, application management, and business operations. Today, integrations are expensive and one-to-one. For instance, while you can currently integrate your application with Google Maps as a composite application, OpSource Connect lets you integrate your app with many others, using just one platform. You can integrate your application with, for example, SAP, salesforce.com, Intuit QuickBooks, NetSuite, and a host of other SaaS and legacy applications. 

Everything is much more dynamic today, and programmers expect that. 

The announcement that Salesforce is integrating directly with cloud-storage Box.net is the tip of the iceberg when it comes to the future of the cloud:

Techcrunch explains what Box.net is thinking:

CEO Aaron Levie says that this is the first step in Box.net's plan to give businesses a secure way to share their files across multiple services on the web. He says that many of the cloud services geared toward the enterprise don't work well together -- oftentimes you'll have to reupload the same content to multiple sites to share or edit it. Box.net wants to help unify these services by serving as the central hub for your uploaded files, which you can then access from these other web-based services. Levie hints that we'll be seeing more integrations with other services in the near future.

What we are witnessing is the future of enterprise IT infrastructure. We have been talking about programmatic access through RESTful APIs for some time now.  This move by Saleforce is an evolutionary step in how enterprise IT will manage its IT infrastructure - it will be a cross-cloud platform, with applications and open access to the storage cloud of your choice.

Security is not an issue, and the future is about cross-cloud collaboration.

Phil Wainewright says that Box.net wants to be the "Switzerland of Data" - he's right and wrong.  Cloud Storage, provided by the various service providers are going to be the "switzerland of data storage."  Vendor lock-in is going by the wayside.

ReadWrite is spot on when they say that "you can start to see how platforms will evolve into service networks - where enterprise users may subscribe and get access to applications that they pay for on a per use basis."

The biggest threat then, is to traditional software vendors, and applications like Sharepoint.  We will see heated debates on this very topic in the days and weeks ahead.

We've discussed ITIL and Cloud Computing and the role of trust as a differentiator for service providers. Yes, we see the evidence that IT Hosting companies and managed service providers are closer to their customers and we see that their differentiation is their commitment to serving the customer.

But Amazon, Google, and Microsoft aren't going away. As they pressure customers to make the switch to the cloud, traditional service providers must find new ways to compete. Step one, of course, is providing alternatives - cloud services, like storage for example.  Step two is to highlight their customer commitment - the relationships they already have and defend this "advantage" by becoming even more responsive. 

So how do you build trust? According to Stephen Covey Jr. trust is built through behavior. His work has identified 13 behaviors which build trust:

1. Talk Straight
2. Demonstrate Respect
3. Create Transparency
4. Right Wrongs
5. Show Loyalty
6. Deliver Results
7. Get Better
8. Confront Reality
9. Clarify Expectations
10. Practice Accountability
11. Listen First
12. Keep Commitments
13. Extend Trust

But how do these behaviors translate to a cloud service delivery model? 

To answer this question, I dug up an old model for assessing service quality - SERVQUAL -  which was introduced to the world of service and retail back in 1988 (those were the days before ITIL).  SERVQUAL has its share of detractors, but even recent research reminds us that it is still a useful model.  In particular, I'm interested in how it can be used to help service providers improve and extend their intangible advantages over the more impersonal big shops.

Over the years, the SERVQUAL instrument has been a popular methodology used to measure consumers' perceptions of service quality. Its five generic dimensions or factors are still valid:

(1) Tangibles: physical facilities, equipment and appearance of personnel.
(2) Reliability: the ability to perform the promised service dependably and accurately.
(3) Responsiveness: willingness to help customers and provide prompt service.
(4) Assurance: includes competence, courtesy, credibility and security; the knowledge and courtesy of employees and their ability to inspire trust and confidence.
(5) Empathy: includes access, communication, understanding the customer; caring and
individualized attention that the firm provides to its customers.

None of these dimensions will change in the cloud, with the exception that some of these dimensions are now virtual and must be proven online (customer support, for example) or through superior automation of work processes.

Let's also analyze the SERVQUAL "gap model," as it was called, and see how it applies to service delivery in the cloud:

Let's look at the meaning of each "gap" - the possible breakdown areas in service delivery:

Gap 1: Customers' expectations versus management perceptions: caused by the lack of a marketing research orientation, inadequate upward communication and too many layers of management.

Gap 2: Management perceptions versus service specifications: caused by an inadequate commitment to service quality, a perception of unfeasibility, inadequate task standardization and an absence of goal setting.

Gap 3: Service specifications versus service delivery: caused by role ambiguity and conflict, poor employee-job fit and poor technology-job fit, inappropriate supervisory control systems, lack of perceived control and lack of teamwork.

Gap 4: Service delivery versus external communication: caused by inadequate horizontal communications and propensity to over-promise.

Gap 5: The discrepancy between customer expectations and their perceptions of the service delivered: caused by the influences exerted from the customer side and the shortfalls (gaps) on the part of the service provider. In this case, customer expectations are influenced by the extent of personal needs, word of mouth recommendation and past service experiences.

Gap 6: The discrepancy between customer expectations and employees' perceptions: caused by the differences in the understanding of customer expectations by front-line service providers.

Gap 7: The discrepancy between employee's perceptions and management perceptions: caused by the differences in the understanding of customer expectations between managers and service providers.

Three of these gaps are directly connected external customers: Gap 1, Gap 5 and Gap 6.  Service providers will find their optimal "trust-building" opportunities here.  Apply Covey's 13 behaviors to each one of these gaps to build on your commitment to your customers.

Amazon, Google, and Microsoft aren't building a high-touch responsive model for their cloud services. But you, the service-provider, already have a high-touch relationship. Your cloud-based SLAs must reflect this advantage. The security issue is just a small part of this reality.

Service providers who dedicate themselves to closing the gaps will succeed in this new world.

The quest for quality service didn't start yesterday. I highly recommend that service providers give Delivering quality service: balancing customer perceptions and expectations by Valarie A. Zeithaml, A. Parasuraman, Leonard L. Berry, a second look.

With all due respect to Cory Doctorow, he's wrong.

In his article Not every cloud has a silver lining (Guardian) he states:

There's something you won't see mentioned by too many advocates of cloud computing - the main attraction is making money from you.

And I suppose all the vendors of physical storage, the hard drives, etc., are interested in your spiritual well being!

Here's the heart of Doctorow's beef with cloud computing:

Rather than buying a hard-drive once and paying nothing - apart from the electricity bill - to run it, you can buy cloud storage and pay for those sectors every month. Rather than buying a high-powered CPU and computing on that, you can move your computing needs to the cloud and pay for every cycle you eat.

The point he misses is that cloud computing exists because it answers a real need.

We aren't prohibiting you from buying physical hard drives, I assure you. In fact, we think physical and cloud storage will work together, complementing each other. It's not one or the other.

Our focus is to provide specific services which deliver quantifiable value for both individual consumers and business users. As we mentioned earlier, the basic promise of cloud computing: instant access to your data anytime, anywhere, on any device, is already a reality. It's all about convenience, ease-of-use, cost, and of course, value-delivered. The cloud is a disruptive innovation.

Let's review the benefits of cloud computing:

For Businesses
In addition to cloud storage, the cloud brings game-changing pricing and service capabilities to disaster recovery, fault tolerance, geographic redundancy, and other solutions that have been prohibitively expensive to everyone except for the largest organizations in the world. Here are some specific drivers of business value:

Financial Benefits: The very nature of "pay per use" makes large upfront financial outlays a thing of the past. So your CFO won't bug you about capital expenditures.  You'll simply have to pay a monthly fee for renting the data center and the services you choose. And yes, that's a monthly operational cost.

Better use of Human Resources: Your IT people don't have to spend time doing repetitive tasks like provisioning and  setting passwords.  That will be done in an automated way by your service provider.

Agile Provisioning: "Time to value" is greatly accelerated using the cloud.  Softlayer, for example, allows lets you deploy on-demand computing instances running enterprise-grade and open source operating systems in as few as five minutes. Can your IT department do that today?

Scalability and Flexibility: The cloud provides customers with the capability to start small and grow with demand, in real-time. Cloud "burstability" allows for rapid scaling to meet demand caused by usage spikes.

Leaner and Greener Infrastructure: The cloud allows companies to outsource their IT infrastructure, and maximize utilization of the computing power of their service provider. This makes for a leaner and greener IT infrastructure for all.

Service Oriented Architecture:  Cloud Storage accessed via RESTful Web Services APIs provides new capabilities for developers.  For the first time, an abstracted, services rich storage layer is a true SOA implementation.

For Individuals
I already hear commercials on TV:

"Are you tired of lugging your laptop everywhere? Are you tired of transferring your files every time you switch devices? Are your running out of space for your endless downloads of videos, songs, and movies? Do you want to access your files anytime, anywhere, on any device? Try cloud computing, and your life will never be the same."

The flexibility cloud computing offers individuals is unparalleled. Again, it is the user-experience which will determine cloud use by the consumer.  And as we see more and more personal files (videos, music, photographs) explode, we'll see a bigger and bigger role for cloud computing.

A final statement. We do want to make money. Like everyone else in the market, we're going to have to deliver value to earn your trust and dollars. And if you find that you get more value from buying your own physical storage or owning and operating your own datacenter, go ahead.  We're betting we can show you a better way, a way that complements your local storage.
