Graviton2 is the second generation of Amazon Web Service's designed processors offering attractive price-performance characteristics. Amazon Relational Database Service (RDS) provides a variety of options for using Graviton2 in RDS. For existing RDS databases, there are also options available for migrating from an x86-based database instance class to a Graviton2 instance class. This lab explores two options first-hand:

1. Restoring a new Graviton2 database instance from a snapshot
2. Modifying an existing x86 database instance to a Graviton2 database instance

As you will see, no porting or code changes are required when migrating from x86 to Graviton2 instances on Amazon RDS. Amazon's Database Migration Service (DMS) can also be a useful tool for the migration use case in this lab but is not in scope for this lab. DMS is covered in other labs.
