Instance type right-sizing - Application Migration Service

Instance type right-sizing

The Instance type right-sizing feature allows Application Migration Service to launch a Test or Cutover instance type that best matches the hardware configuration of the source server.

If you select the Basic option, Application Migration Service will launch a Test or Cutover AWS instance type that best matches the OS, CPU, and RAM of your source server.

Application Migration Service will launch a new instance type after every change of configuration on the source server (ex. added/removed disks, added/removed RAM)

Important

The AWS instance type selected by Application Migration Service when this feature is enabled will overwrite the instance type defined in your EC2 launch template.

Note

Hardware changes and the resulting AWS instance type change may take up to 90 minutes to be processed by Application Migration Service.

If you select the None option, Application Migration Service will launch the AWS instance type as configured in your EC2 launch template. You should select this option if you want to determine the instance type that will be launched in AWS for all your Test or Cutover servers.

The right-sizing instance type selected by Application Migration Service will show on the Server details tab.
