It's hard to believe, but some companies are still hesitating when it comes to cloud computing. They've dipped their toes in the water, but so far they're staying fairly focused on on-premise solutions – even for straightforward cloud use cases such as Disaster Recovery or Backup.

Here's a message for those companies – Get over it.

In case you haven't noticed, data needs aren't just growing – they're exploding. Numbers from IDC predicted that in 2020, there will be more than 10 zettabytes of enterprise-created data. That's 10 million petabytes.

Buying new servers and storage gear every other week isn't sustainable, and no one thinks that the growth of data is just going to stop.

To really see the ROI expanding cloud computing can bring, look at it from a holistic point of view. First, while your OPEX spending will increase, that will be offset by the fact that you'll be able to cut down on hardware purchases and hardware refreshes.

But that also doesn't account for the other returns the cloud can bring. You also need to factor in the benefits like faster speed to market, improved productivity of IT operations AND of your staff , and richer management information.

Once you've done the math – and found a cloud provider that can deliver the dedicated resources your applications demand – it's time to take the toe out of the water and dive in.
