Matching Physical Resources to the Virtualized World of the Cloud

When migrating to the cloud from a nonvirtualized data center, an assessment will need to be performed that will ensure that the virtualized servers have access and are scaled properly to meet their anticipated requirements. This will require performing an inventory of what the hardware requirements are for each operating system and application and scaling the VM instance in the cloud to meet those requirements. In this section, you will be introduced to the required process to evaluate and scale the cloud compute resources properly.

What Are Available and Proposed Hardware Resources?

Cloud service providers will offer a wide range of VM configurations that are designed for different requirements such as general compute, graphics processing, and heavy I/O needs such as a database application; there are also options for CPU and memory-centric configurations. These are generally referred to as instances and are offered prepackaged...
