Is cloud computing secure?

That's because we switching from a world where everything is fixed and understood, to one where our business systems are fluid, virtual systems that aren't tied to any one piece of hardware.

Baize recommends that businesses start moving to the cloud by implementing a private cloud first, as that way you've already changed your IT and are in a much better position to work with public cloud services.

While many concerns about cloud security revolve around governance issues, the answer to the problem of securing the cloud is one that's been around for some time. Securing data rather than applications and servers is an approach that's starting to find a place in modern data centre architectures, as we move from physical servers, to virtual networks and on to private clouds.

We've spent too long thinking about security as a network function, focusing on firewalls and on hardened servers, forgetting the thing that's the most valuable: our data.
