In this chapter, we discussed VMs, a software computer composed by a file structure that specifies the configuration (.vmx) and the virtual disk used to store data (.vmdk) and core components, such as virtual and hardware resources, an OS, and Virtual Machine Tools. A VM can be deployed using different methods depending on the features requested. The use of a content library can simplify the deployment process, and it allows you to easily subscribe to a central content library from your remote sites to have unified access to the installation ISO files and OVF templates.

Snapshots can be used to capture the state of a VM at a specific point in time so that we can quickly revert to a working version if necessary. A typical use case of snapshots is the patching process...
