With technology like cloud computing you basically have two options. There's the choice between private and public cloud. In order to gage which is right for your business it's imperative that you understand the difference between them both.
The chances are your company already operates on some form of private cloud. Private cloud computing will be something like an internal intranet or any way your business shares information internally behind your own firewall. So long as you're not physically storing your work in a fixed location like your desk top and sending it to another location you're working in a private cloud. A public cloud would mean you were storing or working on data that's kept beyond your own internal network. A typical example most people are familiar with here is Google docs. Google docs allows you share and collaborate on multiple documents in real time. You can even share these documents with people outside your organisation. This is a very simplistic example of public cloud computing. If you want to get all your data centers on the cloud you'll need to invest in a proper cloud hosting service. This would also involve a cloud storage service where by all your data is held, backed up and hosted via a virtual server through virtualization.
This means you've eliminated the need to host your own data center. As you'd no longer be having to pay to run and cool your servers in your data center you'd see huge savings. You're also only using the space you're actually using. You no longer have to pay for server space that's sat there just in case you might need it. If you do need more space you can access it instantly and the same applies if you're no longer using it so you're just paying for what you're using.
