    Hello samuel,

    Thanks for the feedback.

    Based on the requirements in the question, you need to ensure the database must be scalable and highly available. If you would only use Read Replicas, this won’t satisfy the requirement “high availability”.

    The option “Migrate the local database to an RDS Multi-AZ deployments configuration with Read Replicas” is the most suitable answer in the scenario because it is highly available (Multi-AZ) and can serve high volume read traffic (Read Replica – scalable).

    Amazon RDS Multi-AZ deployments provide enhanced availability and durability for database instances, making them a natural fit for production database workloads.

    Read Replicas make it easy to elastically scale out beyond the capacity constraints of a single DB instance for read-heavy database workloads.
