Amazon RDS (Relational Database Service) is a popular managed database service that has been used by companies to set up, operate, and scale databases for web and mobile applications. However, modern high-scale applications can have tens of thousands of clients, which can lead to maintenance issues and higher costs when paying per database instance. To solve this problem, AWS launched RDS Proxy, an intermediary between the application and database that pools and shares connections from application clients, improving database efficiency and application scalability. Datadog's Amazon RDS Proxy integration provides visibility into client connections and query throughput, allowing users to quickly troubleshoot connection errors, identify when to scale connections, and ensure optimal proxy performance and connection reusability. The integration also helps users monitor key metrics such as connection setup failures, database connection setup failures, target group availability, and pinned connections, enabling them to identify issues with authentication, security, and database instance availability, and optimize their RDS Proxy configuration for better performance and scalability. With Datadog's Amazon RDS Proxy integration, users can get started by monitoring key metrics from their proxies alongside other AWS infrastructure and services, troubleshoot database connection errors, understand when to scale connections, and ensure proxy performance and connection reusability, all from a single pane of glass.
