Troubleshooting MySQL connectivity

Is using RDS Proxy recommended while connecting to RDS?

Amazon RDS Proxy is a fully-managed, highly-available database proxy for Amazon Relational Database Service (RDS). It makes applications more scalable, secure, and resilient to database failures. Amazon RDS Proxy sits between your application and relational database to efficiently manage connections to the database and improve scalability of the application.

When setting up a private network link to MySQL, Amazon RDS Proxy can help with:

  • Connection pooling — RDS Proxy helps manage database connections by pooling them and reusing them across multiple application connections. This reduces the overhead of establishing new connections for each database request and improves performance.
  • Scalability — it automatically scales connection capacity based on demand, allowing applications to handle a high number of concurrent database connections without overwhelming the database instance. It also helps distribute the workload across multiple database instances, enabling horizontal scalability.
  • Connection multiplexing — RDS Proxy multiplexes multiple database connections over a single secure connection. This reduces the number of connections to the database, conserving system resources and reducing the chance of hitting connection limits.
  • Security — it integrates with AWS Identity and Access Management (IAM), allowing fine-grained control over who can access the proxy and underlying database. It also supports Amazon virtual private cloud (VPC) endpoints, enhancing security through private connectivity.
