Cloud computing is often pitched as the ultimate in IT. Infinitely malleable, it's whatever package of flexibility, economy and let-someone-else-deal-with-the-hard-parts ease the proponent wants it to be. Events in recent months, however, have ripped deeply into the credibility of visions of cloud nirvana, reinforcing the value of in-house IT capability.
Not least is the failure of Nirvanix, a well-funded provider of enterprise storage in the cloud. Suppliers fall in every industry, but Nirvanix storage departed in a way that left customers deeply disappointed -- not just about one company, but about the prospects for cloud services overall.
Nirvanix appeared to be doing well, and then it faced sudden financial meltdown. With little warning, it told clients they had just two weeks to retrieve their data and make other arrangements. Two weeks would be a hellacious timeline for the most agile Web shop. But for enterprise IT shops running databases, applications and analytics that their businesses depend on day to day and minute to minute, that's insanely little warning.
Even optimistically assuming that a suitable alternate infrastructure or service was immediately available, two weeks isn't much time to get data out of Nirvanix storage, onto an alternate infrastructure, qualified for production use, and then up and running. That's especially true during a high-stress period when every other customer is rushing to do the same thing.
This kind of failure mode, in which everyone freaks out all at once, affects other shared services, such as those for Disaster Recovery as a Service. Recovering from a single-business failure like a data center fire is a great use for cloud computing. But if a storm, an earthquake or another disaster affects a wider area, everyone nearby will be forced to evacuate, fail over or restore simultaneously. The shared, amortized cost model that makes cloud look magically cheap is less appealing when everyone bangs on that shared infrastructure at the same time. There probably won't be enough resources to go around -- at least not with the great performance and responsiveness one can see when those shared resources aren't running at frantic, historic high-water levels.
Moving back on-premises after Nirvanix storage failure
Nirvanix's failure as a well-funded provider is noteworthy because we're deep into the so-called Cloud Age. But it's actually just the latest in a series of failed storage service offerings going back a decade. See also Cirtas and StorageNetworks, among others. "Go with big, proven, stable providers" is trusted advice against the vagaries of startups. But Iron Mountain and EMC also shuttered storage-in-the-cloud services in recent years. Where exactly is an enterprise supposed to go for safe, solid ground?
Home. Back to providing -- or at least managing -- those services in-house. Or to a multisource strategy.
It turns out you can. Later in the year, we learned that national security agencies are siphoning off large swaths of all telephone records and data communications. One program, "MUSCULAR," apparently taps all Google inter-data center traffic. That shocked even Google. The once-theoretical risks around data privacy and security have become urgent concerns.
Now, cloud computing isn't going away. Even with proven privacy and availability exposures, the economics and opportunities remain compelling for many uses. The extreme "everything will be cloud!" mania, however, is dead. Most enterprises won't stand for it. It would be negligent to do so. They'll use cloud resources but in measured, cautious, hybrid ways. That makes the ability to provide flexibility, efficiency and elastic scalability in-house -- in other words, modern infrastructure -- central to the enterprise IT mission.
