AWS has a lot of different instance types and it can be difficult to decide which instance type would be the best for a particular use-case. In this article, we will compare three popular instance types: C6g, M6g and R6g, across various dimensions such as their specs, their performance as well the cost.

Introduction

AWS Relational Database Service (RDS) is a managed database service that was launched almost 10 years ago. Over the last 10 years, application patterns have evolved which has led to various challenges when it comes to interacting with the database:

• Applications, especially serverless applications, have a large number of open DB connections. RDS only allows a limited number of open connections.
• Custom failure handling code can become hard to manage and error-prone. Handling database failovers is one such example of handling failures.

AWS RDS proxy is a fully-managed database proxy for Amazon RDS. RDS proxy works by pooling and sharing DB connections and thus makes applications more scalable as well as resilient to database failures. They key benefits of using RDS proxy are:

• Connection pooling and sharing: Improves application performance by reducing the number of open database connections
• RDS proxy helps improve application availability during failure scenarios such as a database failover.
• RDS Proxy gives you the choice to use IAM authentication for connecting to the database, thus removing the need for database credentials in the application code.

RDS proxy is currently available for Aurora MySQL, Aurora PostgreSQL, RDS MySQL and RDS PostgreSQL.
