When thinking about Cloud Security, think of virtual machines in a data center as resources. And if you also think of security as an application, just like any other application, then security is a resource that you can scale up or down. Virtual machines allow us to do things in the small, such as targeting a virtual machine to look for specific areas of security concern.
