Welcome to this live hands-on AWS lab, where we will be working with the Relational Database Service (RDS).

<!-- NOTE: This lab may take 10-15 minutes to provision. -->

This lab will provide you with hands-on experience with:

  • Enabling Multi-AZ and backups
  • Creating a read replica
  • Promoting a read replica
  • Updating the RDS endpoint in Route 53

Multi-AZ and read replicas serve different purposes with RDS. Multi-AZ is strictly for failover, as the standby instances cannot be read from by an application. Read replicas are used for improved performance and migrations. With read replicas, you can write to the primary database and read from the read replica. Because a read replica can be promoted to be the primary database, it makes for a great tool in disaster recovery and migrations.

Good luck, and enjoy the hands-on lab!
