Cloud Storage: Why it’s all about the ecosystem

Thursday, July 15th, 2010

What makes today’s “storage as a service” providers more likely to succeed than those of 10 years ago? On the surface, much can be said about technology improvements and nearly ubiquitous bandwidth availability as catalysts for customer acceptance and adoption.  Layer on top of that proven economies of scale and a pay-as-you-go model from Amazon and other providers and you no longer have a promise but rather a very real and very attractive cost model for many businesses.

Why ASPs had it tough

While technology and cost savings are making a difference, an often neglected differentiator between the xSPs of yesteryear and the XaaS ecosystems of today may be the actual presence of an ecosystem versus a monolithic provider. Consider that an application service provider (ASP) who decides to bring a end-to-end solution to market needs

  • Economic and scalable infrastructure
  • Application expertise, and
  • A way to bridge the solution to the enterprise

A rather ambitious undertaking, I’d say. Tradeoffs in any of the above areas may reduce the business value or compromise the end solution.

Let’s look at a more concrete example relevant to storage. Say I have developed unique technology that reduces my data sizes by up to an order of magnitude. If I wanted to roll this technology into a data backup solution following the ASP model, I would (1) build the backup application software, (2) build the data reduction technology that connects to storage and (3) build out the storage infrastructure to house the data. Rather than attempting to tackle all three steps myself, I could turn to the existing ecosystem to leverage others’ core strengths and expertise in order to optimize the overall solution.

Enter the ecosystem

Working within the ecosystem, my technology could leverage best of breed cloud storage, replete with availability and cost efficiency options from a number of mature storage providers. But what if I could also leverage existing backup software so that IT administrators weren’t forced to rip and replace, not to mention learn new solutions?  And what if I could deliver my solution as software that bridges a customer’s existing technology to their choice of multiple best-of-breed cloud providers? For starters, I benefit from a significantly faster time to market, the ability to retain focus on enhancing my core value proposition, and access to a larger addressable market due to ease of integration. Users benefit from a broad array of choices, no lock-in, lower costs and user-friendly integration. Sure, competitors could join the ecosystem but that only further benefits end-users by enabling additional choices.

Sound interesting? You bet.  The intelligent storage cloud is all about combining the best of the best, whether it is the expertise of service providers, solution providers or enablement providers.  The power of an ecosystem is that it is much greater than than the sum of its parts.

What do you think is the key differentiator between the storage clouds of today and the early storage service providers?

Why You Never Need to Worry about Cloud Storage Lock-in

Thursday, July 8th, 2010

You’ve probably heard the news from a variety of sources: EMC has shut down their EMC Atmos Online service. In case you missed it, you can read EMC’s official statement or read reaction to it here, here, here, here, here or here. To be clear, Atmos online has not vanished; rather, it no longer supports “production” usage of the online cloud storage service. For many existing users, this does not pose a major problem since the Atmos production service is still available from a robust Atmos partner ecosystem including AT&T, Hosted Solutions and PEER1, creating an easy migration path. Nonetheless, the shutdown has prompted many in the media, analyst and user community to question what happens when a cloud storage provider shuts down without a clean migration path.

With CloudArray, the answer is simple: you migrate your data to one of the many providers CloudArray supports. Because CloudArray masks the provider specific APIs and allows applications to connect to cloud storage via standard protocols, such as iSCSI or any file system layered on top, moving data between providers is simple. With the option of full local copies, you can always have a copy of your data on-premise as well. If your primary data resides in the cloud, why not have a copy locally? As an added benefit, CloudArray allows you to store data on multiple providers simultaneously. Multiple secure copies of data mean improved data availability.

While the shutdown of EMC Atmos online may send a cautionary message to some, you can rest assured products such as CloudArray have been specifically designed to protect users from cloud storage lock-in and the associated risks. We knew cloud provider lock-in was a concern when we started TwinStrata. Even our name, TwinStrata (which means dual clouds), was chosen to acknowledge the requirement for more than one provider.

So if you’re thinking of deploying cloud storage, download CloudArray and breathe easy…

Storage Cloud-o-Nomics

Thursday, November 5th, 2009

You may have read a recent blog entry by a leading industry analyst addressing cloud storage ROI: 20TB of public cloud storage as a service at Amazon’s S3 rate of $0.15/GB per month totals $3,000 per month, or a whopping $36,000 per year. Some do-it-yourselfers responded they can build 4 storage arrays for this one-year price. But can acquiring a glut of storage capacity give your business offsite data protection? Can it instill confidence that your business will be able to survive a complete loss of your primary site data?

We recently used Clarity AP to conduct a total cost of ownership (TCO) analysis of cloud storage as an offsite replicated tier of storage accessible via our cloud gateway, CloudArray. For the analysis, we assume a company with a single site for data storage and linear capacity growth over 3 years. We calculated the 3 year TCO of an in-house implemented offsite tier of replicated storage versus replicated storage to the cloud. We plotted the capacity crossover point up to which cloud storage holds a cost advantage.

While we invite everyone to look at the full report, here’s a brief summary:

Cloud storage may make sense for capacities up to 60TB for replicated data. At these capacities, cloud storage benefits from a pay as you go model that does not suffer the underutilization experienced in storage arrays. As a remote site data protection solution, cloud storage substantially reduces the need for offsite infrastructure and management.

The chart below illustrates the crossover point:

3-yr TCO for offsite replicated storage

3-yr TCO for offsite replicated storage

For the initial TB of capacity, costs for an in-house solution over a 3 year period are $233,492, compared to $79,794 for cloud storage. For 20 TB, there is a $100,000 savings when data is replicated to a cloud provider.

The report lists results, configurations and cost assumptions. The analysis purposely neglects to factor local site floor/power/cooling since some may argue these are sunk costs. It also does not address application/compute failover which is a separate analysis.

Conclusion

Based on the results of this analysis, cloud storage can be very compelling for companies replicating up to 60 TB to a public cloud. For a mid-sized company or departments within a larger organization, this represents a substantial capacity range across which cloud storage presents a strong ROI. Watch for this range to expand even higher over the course of the next 3 years with more favorable cloud pricing and tiers of service.
