This lesson focuses on the services found within a virtual data center:
All hosts in the virtual data center can access the services depending on the configuration of the virtual machines. When configuring, it is important to understand the difference between virtual machines and physical machines. Physical machines are a large data center with all servers loaded in one place and need to be re-booted after changes, whereas virtual machines are easier to change quickly without reboots, you can also over allocate your memory without causing performance issues.
