To provide enhanced performance and scalability, Amazon RDS on VMware adds support for read replicas for MySQL and PostgreSQL databases. You can create read replicas of a source DB instance to serve high-volume application read traffic, thereby increasing aggregate read throughput. A read replica can also be promoted to become a standalone DB instance if the source DB instance fails.  

RDS on VMware read replicas are available to all RDS on VMware customers running PostgreSQL versions 10.9 and 10.10, and MySQL version 5.7. See the RDS on VMware User Guide for more details.
