What is Amazon RDS for MySQL?¶
Amazon RDS (Relational Database Service) for MySQL is a managed database service that simplifies the setup, operation, and scaling of MySQL databases in the cloud. Users benefit from automated backup, failover, and scaling features, allowing businesses to focus on application development instead of database management. RDS takes care of routine database tasks like provisioning, patching, backup, and recovery.
Understanding Extended Support¶
Extended Support offers an extended timeline for running a major version of MySQL beyond the standard support end date. With this extension, RDS provides critical security updates and bug fixes, ensuring your system remains secure while transitioning to a newer version. The typical duration of Extended Support is up to three years, allowing businesses ample time to manage upgrades without immediate pressure.
