What is the difference between "RDS Read Replicas" and "Multi-AZ" deployments?
Correct! Well done.
Incorrect.
The correct answer is B) Multi-AZ provides a synchronous standby for failover/high availability (not used for reads normally), while Read Replicas are asynchronously replicated copies that can serve read traffic to offload the primary, and can be promoted to standalone databases
Correct Answer
Multi-AZ provides a synchronous standby for failover/high availability (not used for reads normally), while Read Replicas are asynchronously replicated copies that can serve read traffic to offload the primary, and can be promoted to standalone databases
Multi-AZ focuses on availability via synchronous replication to a standby (not normally readable), while Read Replicas use asynchronous replication and can actively serve read queries to help scale read-heavy workloads.
