The cloud storage provider Nirvanix's demise, a little over a month ago, was a non-event despite initial panic. Why? No data loss.
When the news started to leak that Nirvanix was getting ready to shut its doors, the industry went into full panic mode. There were predictions of more failures and a lot of "See, I told you so" comments from cloud naysayers. But 28 days later, I was at Amazon re:Invent, and nobody really cared.
What happened? Why has Nirvanix so quickly become only a road bump on the seemingly unstoppable cloud raceway?
First and probably most importantly, no one I can find has lost data. Despite the gloom-and-doom predictions, it seems as if everyone got their data out. I still think there is legitimate concern over what happens to the copies of data still on Nirvanix hardware, but the fact that there have been no reported incidents of data loss is amazing.
Why did this happen? Simple, the industry as a whole responded quickly. It was essentially a disaster without a natural element such as a storm, fire, or flood. Some vendors responded because they smelled a business opportunity. Others responded because they had clients using the Nirvanix cloud, and they had some level of obligation to move those clients off it. And maybe a few companies responded because it was the right thing to do. But essentially, we had a disaster, the industry responded (for various reasons), and no one got stuck with data in a cloud that had been shut down.
We spoke to several gateway companies -- which provided on-premises-to-cloud-storage translation appliances -- that were able to move data out of the Nirvanix cloud. For clients whose data sets were too big to copy back to the on-premises appliance and to another cloud, these gateway companies worked with other providers to tap directly into the Nirvanix datacenter and pull the data out. Most interestingly, these companies report that no client has given up on cloud storage. All of them simply moved to other providers. In other words, the Nirvanix users remain sold on the cloud promise, and they want to continue using the cloud as a component of their solution.
Clearly, there are lessons to be learned from the Nirvanix shutdown. We don't want to have to go into full scramble mode the next time there is a cloud failure. One of the positives from this event is that we now know that cloud storage is not some mythical creation that's immune to failure. It is a business and a datacenter, and it has weaknesses from which organizations need to protect themselves.
Interest in cloud mirroring (either via an application or the gateway) is on the rise and provides the ultimate protection from a cloud failure. That is an expensive option, though. A more cost-effective option would be for cloud providers to consider tape as a backup. Imagine if Nirvanix had a copy of all its data on tape -- it could have just shipped everyone their data. With LTO's LTFS capability, we wouldn't even have had to worry about what backup application they used.
But in the end, protecting yourself from a cloud failure is your responsibility as the IT professional. If you have applications that are entirely cloud based, the ability to pull that data into your datacenter might be the most cost-effective choice. Again, you can even use tape to keep costs down. If you are using cloud storage as a backend to on-premises applications, making an extra copy of data before it goes to a single cloud provider is a smart move.
Cloud compute and cloud storage come away from the Nirvanix shutdown essentially unscathed. IT professionals come away a little wiser, with a few more lessons under their belts. And cloud naysayers have to find another reason to complain.
Buying power and influence are rapidly shifting to service providers. Where does that leave enterprise IT? Not at the cutting edge, that's for sure: Only 19% are increasing both the number and capability of servers, budgets are level or down for 60%, and just 12% are using new microtechnology.

Google in the Enterprise SurveyThere's no doubt Google has made headway into businesses: Just 28 percent discourage or ban use of its productivity products, and 69 percent cite Google Apps' good or excellent mobility. But progress could still stall: 59 percent of nonusers distrust the security of Google's cloud. Its data privacy is an open question, and 37 percent worry about integration.
InformationWeek Tech Digest, Nov. 10, 2014Just 30% of respondents to our new survey say their companies are very or extremely effective at identifying critical data and analyzing it to make decisions, down from 42% in 2013. What gives?
