RDS


RDS (Relational Database Service)

  • What it is: The standard managed SQL service. You choose the engine (MySQL, PostgreSQL, SQL Server, Oracle, or MariaDB), and AWS manages the hardware, backups, and patching. It is for standard applications.

  • Data Engineer Note: This is usually your "Source" system (OLTP). You will likely be writing pipelines to extract data from here.

  • Equivalents:

    • GCP: Cloud SQL

    • Azure: Azure SQL Database / Azure Database for MySQL
