Virtual machines An architect has to determine whether the virtualization environment is able to handle the below mentioned enterprise’s VM needs.
• Security maintenance: An advantage of using VMs is the abstraction at the physical hardware level that translates to individual operating systems. These individual operating systems limit the attack surface to the hypervisor and has the ability to filter the activity of the guest.
• Load handling: Virtual machines make perfect sense when an enterprise has a powerful host server that can handle the load of multiple VMs.
• Automation support: A full-fledged VM platform, such as vSphere, includes a variety of automation features for deployments and proactively manages compute, memory and storage resources.
• Ensuring portability: A single version of an application, in most cases, should be able to run on a different platform without any modification.
