In today’s modern world, virtualization is often used to help mitigate cost as well as to provide flexibility in scaling for performance workloads. It’s very easy to scale a virtual machine with a few mouse clicks and a brief outage while it reboots. If you are running VMWare on-premises, this is a few minute outage. If you are running in the cloud, you can simply resize the virtual machine to a higher compute tier and upon reboot, poof, you have more compute.
