The Developer team is planning to deploy a new application that will use the Amazon RDS database. This application will be initiating a large number of connections with the database & these connections will be opened at a very high rate. The Database Lead is concerned about the load on DB instance memory & compute resources while using this application. You have been assigned a task to select a service that will reduce the load on the database & improve application performance with RDS.
Which service is best suited to meet this requirement?

Answer options:

A.Amazon RDS Proxy
B.Amazon RDS Read Replica
C.Amazon RDS Multi-AZ
D.Amazon RDS Snapshots

Correct Answer: A
Amazon RDS Proxy is a fully managed proxy service for Amazon RDS. It allows applications to pool & share connections established with the RDS database. This can help reduce the load on RDS databases, especially for applications that initiate a large number of connections with RDS databases.
Option B is incorrect as Amazon RDS Read Replica allows reading from multiple RDS DB instances. This will not be useful for applications initiating a large number of connections with the Amazon RDS database.
Option C is incorrect as Amazon RDS Multi-AZ provides high availability for Amazon RDS database & failover to standby DB instance in case of failure to primary DB instance. This will not help improve application performance while accessing RDS databases.
Option D is incorrect as Amazon RDS Snapshots is an invalid option for this case. Snapshots can be used to create DB instances in case of disaster.
