Nearly every week, news articles crop up shouting about someone's cloud data
or application temporarily -- or in some rare instances, permanently --
disappearing. Name a vendor and they've probably been in the news. "Ack!" and
"Not ready for prime time!" go the headlines. Cloud computing may be the future,
but it isn't ready for the enterprise.
Or is it?
[ Gartner details seven cloud computing risks. | Fuzzy on cloud computing?
Here's what it really means. |
For every big news story making the headlines about cloud data availability
issues, I bet there are thousands more incidents of data loss on noncloud
systems. Yes, I know that there are hundreds of thousands times more noncloud
systems (or whatever the ratio is), but think about how many people you know who
have lost everything on their computers because they didn't have a recent
backup. How many companies have you worked at that thought they were getting
good data backups -- but weren't? How many companies have lost data, then had a
hard time recovering it, only to mess up a second time with seemingly no lesson
learned?
We all know those companies. Heck, how many of people reading this article have
perfect backups of our own data? Be honest.
Because cloud vendors are charged with supporting large amounts of data and
multiple customers, by their very nature, they have to have their data
protection policies and procedures down to a science. If a server goes down,
they must have a hundred like it ready to take over in an instant. They require
redundant Internet access, power supplies, air-handling systems, and so on. They
need to have a handle on round-robin patching, fluid virtual machines,
performance metrics, event-log monitoring, alerting, and every other aspect of
systems management that most companies hope to optimize one day. It's imperative
that cloud vendors understand those topics from day one.
Your company may have some 24/7 applications, maybe even a few 24/7 datacenters,
but in the cloud vendor world, every aspect of their environment is 24/7. It
isn't the exception -- it's the only rule.
This doesn't mean cloud vendors are perfect. Obviously the popular headlines and
their legal contracts say they aren't. But I'll postulate that cloud data and
application reliability already beats the reliability experience of most
companies and people today.
