Appendix A: Amazon EC2 Instance Size

Amazon Elastic Compute Cloud (Amazon EC2) provides a wide selection of instance types and sizes optimized to fit different use cases, giving you the flexibility to choose the appropriate instance type for your workload.

By default, the EFS-to-EFS backup solution uses the c5.xlarge Amazon EC2 instance type, but you can choose a different instance type depending on how you want the solution’s file system to consume burst credits. For example, a customer with on-going production reads to their source Amazon Elastic File System (Amazon EFS) file system might choose a smaller instance type for the solution to save burst credits for the production load.

To change the instance size, modify the following mapping in the AWS CloudFormation template:

c5.xlarge: {"Arch":"HVM64"} us-east-1: {"InstanceSize":"c5.xlarge"}

For example, to change the instance size to a c5.large, make the following change:

c5.large: {"Arch":"HVM64"} us-east-1: {"InstanceSize":"c5.large"}

We recommend that you use a compute-optimized instance type for optimized performance and cost efficiency. If you choose to use a different instance type, we recommend that you use a rigorous performance testing and optimization process to choose an instance type that optimizes the consumption of burst credits.
