Cloud is not a new technology and is quite simply a marketing buzz word.
Computing has been using the “cloud” concept since the very early days when one computer mainframe was the size of multiple rooms to today's portable laptops that can do banking and instant messaging online.
For example, when you checked your web email say 10 years ago. You were using the "cloud". There are email service hosting software residing in multiple servers all over the world serving your email needs.
Now the very same concept applies to security platform software. There are servers hosting your security software in multiple servers across the globe. So, is it good to use cloud for my security needs?
As always, we do not introduce additional system component unless there is a strong justification. If you travel away from home much and really need to be able to reach your system remotely, then we can start studying this possibility.
