The next time someone tells you that in the near future, absolutely everything will migrate to the cloud, offer a one-word response: Unix.
Cloud computing isn't a topic that managers are neutral about. However, that doesn't mean that the decisions we make about cloud rollouts are logical.
Flash is an obvious solution for high-speed storage, but what proportion of network storage is typically devoted to it? The answer might be less than you think.
'Hyperscale' cloud providers (the big guns like AWS and Azure) have assumed a dominant position in the cloud market. But scale brings its own set of problems, as any obese person can attest.
Hybrid cloud -- a mixture of on-premises gear and commercial cloud services -- is a common approach in scenarios where pure cloud isn't acceptable for whatever business reason. But what happens when you want to throw more than one cloud service into the mix?
It's conventional to talk about numbered tiers when discussing storage technology: Tier 1 is the best-performing but also the most expensive. If you're trying to choose the most suitable storage for a particular platform, however, it may be helpful to stop using the numbers.
Management invariably wants IT to be faster and cheaper and more reliable. Delivering that trifecta is almost impossible, but it's worth bearing in mind that improving raw performance doesn't always have to be the goal. You may need speed, but you probably don't need speed everywhere.
