AWS Relational Database Service (RDS) Proxy are a way to access your RDS databases via a managed service rather than a direct connection to RDS.

• Improves the database efficiency by reducing the burden of managing large number of open connections. Thus reducing the amount of CPU and RAM requirements.
• RDS proxy is serverless
• Autoscaling
• provides high availability through multi-AZ configuration
• Reduces the time of failover by up to 66%
• RDS Proxy is supported by:
  • MySQL
  • PostgreSQL
  • MariaDB
  • MS SQL Server
  • Aurora
• No code change is required on you applications.
• It enforces the use of IAM authentication for database access
• It requires the credentials to be stored in AWS Secrets Manager
• RDS Proxy is not publicly accessible and only good within your VPC
