How Amazon EC2 instance recommendations work in AWS Migration Hub
This feature recommends the most cost-effective Amazon Elastic Compute Cloud instance type that can satisfy your existing server specifications and utilization requirements while taking into account your selected instance preferences. The server specifications that are used to generate your recommendations are:
-
Number of processors
-
Number of logical cores
-
Total amount of RAM
-
Operating system family
-
Usage data including peak, average, and percentiles of CPU and RAM
Amazon EC2 instance recommendations returns the best Amazon EC2 instance type match based on server specification as well as the performance dimensions you provided. To match the performance dimensions, the service adjusts the server’s specification by multiplying the original CPU and RAM values by the usage percentage.
