AWS RDS stands for Amazon Relational Database Service. It's a fully managed relational database service provided by Amazon Web Services (AWS) that simplifies the setup, operation, and scaling of relational databases in the cloud.
AWS RDS supports multiple engines like MySQL, PostgreSQL, MariaDB, Oracle, Microsoft SQL Server, and Amazon Aurora. It handles routine database tasks such as provisioning, patching, backup, replication, high availability, recovery, and automated backups, allowing users to focus on application development rather than database management.
