Public and private clouds are not interchangeable but can co-exist

The move to the cloud is inevitable – that much we know. All the experts agree, even if their figures vary somewhat. The question is – is it possible to move to the cloud too fast?

Gartner says that nearly half of large enterprises will have hybrid cloud deployments by the end of 2017. And in its 2015 Global Cloud Index, Cisco projects that by 2019, 83 per cent of all data centre traffic will come from the cloud and 4 out of 5 data centre workloads will be processed in the cloud.

But what those figures don’t tell you is that there is absolutely no point in rushing to be among that 83 per cent if you don’t plan properly. And that means choosing the right cloud as well as the right provider – or providers.

Why does the right cloud matter? Because while hosted private clouds – if chosen carefully – can be more-or-less analogous to on-premises solutions, public clouds most definitely are not. If you try to move what we’d call ‘traditional’ or legacy applications that haven’t been re-platformed on to a public cloud, you may find yourself paying out a significant sum of money to be rescued.

That’s not to say that you shouldn’t opt for public cloud, but you should do so only when it’s the right thing for that specific application or task. In the meantime, a private cloud can still provide an efficient solution and save you money if chosen wisely. And you can use both blended together.
