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?
Click on the arrows to vote for the correct answer
A. B. C. D.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.

Amazon RDS Proxy is a fully managed database proxy that sits between the application and the database. It provides efficient pooling and reusing of database connections, which reduces the load on the database instance's memory and compute resources. Amazon RDS Proxy automatically scales up or down based on application demands, making it suitable for applications that require a large number of connections. It can also improve application availability by automatically handling failovers and connection retries.
Amazon RDS Read Replica is a database replica that provides read scalability by replicating data from the primary database instance to a secondary instance. While it can reduce the read load on the primary database instance, it does not help with reducing the connection load on the database instance.
Amazon RDS Multi-AZ is a feature that provides high availability by replicating the database instance to a standby instance in a different availability zone. It can also perform automated failover in case of a primary instance outage. While it provides high availability, it does not help with reducing the connection load on the database instance.
Amazon RDS Snapshots is a backup feature that takes a point-in-time backup of the database instance. It can be used to restore the database instance in case of data loss or corruption. It does not help with reducing the connection load on the database instance.
Therefore, Amazon RDS Proxy is the best-suited service to meet the requirement of reducing the load on the Amazon RDS database and improving application performance in this scenario.
