Right-sizing virtual machines

Right-sizing a virtual machine means allocating the correct amount of CPU, memory, and storage resources that are required to support a virtual machine's workload. The optimal performance of the virtual machine and the efficient use of the underlying hardware are both obtained through right-sizing virtual machine resources.

In a physical server environment, it can be difficult and time-consuming to add resources:

1. Compatible parts will need to be identified
2. The parts will need to be ordered
3. You will likely need to wait weeks for the parts to arrive
4. Someone will need to be in the data center
5. The server will need to be shut down
6. The server will need to be removed from the rack and opened up
7. The parts need to be installed

Because of this, physical servers are often configured with more resources than are actually required to ensure that there are...
