It is a scalable solution. In F5 BIG-IP i5800, if you have assigned a single CPU and memory for a virtual instance and if it increases, you can just add a CPU and memory to the existing vCMP. What you have to do is spin one more virtual instance with the two CPUs and double the memory, like eight GB memory, for example. You can't just increase the existing VirtualBox. You have to create another VirtualBox parallel, download the configurations, and import it. My company provides one banking application to around ten customers. My company has around seven virtual instances and seven applications, each application having around 70 customers running on one F5 BIG-IP i5800. My company has created seven VirtualBox.
