Your MySQL 5.7 and PostgreSQL 11 databases will probably be routinely enrolled into Amazon RDS Prolonged Help

As we speak, we’re saying that your MySQL 5.7 and PostgreSQL 11 database situations working on Amazon Aurora and Amazon Relational Database Service (Amazon RDS) will probably be routinely enrolled into Amazon RDS Prolonged Help beginning on February 29, 2024.

It will assist keep away from unplanned downtime and compatibility points that may come up with routinely upgrading to a brand new main model. This supplies you with extra management over whenever you need to improve the main model of your database.

Till group finish of life (EoL), the MySQL and PostgreSQL open supply communities handle widespread vulnerabilities and exposures (CVE) identification, patch era, and bug fixes for the respective engines. The communities launch a brand new minor model each quarter containing these safety patches and bug fixes till the database main model reaches group finish of life. After the group finish of life date, CVE patches or bug fixes are now not accessible and the group considers these engines unsupported. For instance, MySQL 5.7 and PostgreSQL 11 are now not supported by the communities as of October and November 2023 respectively. We’re grateful to the communities for his or her continued help of those main variations and a clear course of and timeline for transitioning to the latest main model.

With RDS Prolonged Help, Amazon Aurora and RDS takes on engineering the vital CVE patches and bug fixes for as much as three years past a significant model’s group EoL. For these 3 years, Amazon Aurora and RDS will work to determine CVEs and bugs within the engine, generate patches and launch them to you as rapidly as doable. Beneath RDS Prolonged Help, we’ll proceed to supply help, such that the open supply group’s finish of help for an engine’s main model doesn’t depart your purposes uncovered to vital safety vulnerabilities or unresolved bugs.

You would possibly marvel why we’re charging for RDS Prolonged Help slightly than offering it as a part of the RDS service. It’s as a result of the engineering work for sustaining safety and performance of group EoL engines requires AWS to speculate developer sources for vital CVE patches and bug fixes.

Nonetheless, we heard a lot of suggestions from prospects that these automated upgrades might trigger their purposes to expertise breaking modifications and different unpredictable conduct between main variations of group DB engines.

PostgreSQL 15 on Aurora PostgreSQL helps the Aurora I/O Optimized configuration, Aurora Serverless v2, Babelfish for Aurora PostgreSQL, pgvector extension, Trusted Language Extensions for PostgreSQL (TLE), and AWS Graviton3-based situations in addition to group enhancements. Upgrading to RDS for PostgreSQL 15 supplies options comparable to Multi-AZ DB cluster deployments, RDS Optimized Reads, HypoPG extension, pgvector extension, TLEs for PostgreSQL, and AWS Graviton3-based situations.
