RDS Quiz
An application currently uses AWS RDS MySQL as its data layer. Due to recent performance issues on the database, it has been decided to separate the querying part of the application by setting up a separate reporting layer. Which of the following additional steps could also potentially assist in improving the performance of the underlying database?
A. Make use of Multi-AZ to setup a secondary database in another Availability Zone.
B. Make use of Multi-AZ to setup a secondary database in another region.
Make use of Read Replicas to setup a secondary read-only database.
D. Make use of Read Replicas to setup a secondary read and write database.
C. Make use of Read Replicas to setup a secondary read-only database.
AWS Documentation mentions the following:
Amazon RDS Read Replicas provide enhanced performance and durability for database (DB) instances. This feature makes it easy to elastically scale out beyond the capacity constraints of a single DB instance for read-heavy database workloads. You can create one or more replicas of a given source DB Instance and serve high-volume application read traffic from multiple copies of your data, thereby increasing aggregate read throughput
