What is Amazon RDS?

Amazon Relational Database Service (RDS) is a managed relational database service that provides you with six familiar database engines to choose from, including Amazon Aurora, PostgreSQL, MySQL, MariaDB, Oracle Database, and SQL Server. RDS makes it easy to set up, operate, and scale a relational database in the cloud by handling routine database tasks such as provisioning, patching, backup, recovery, and scaling.

Core Features of Amazon RDS

• Automated Backups: RDS automatically performs daily backups of your database (capturing both system snapshots and transaction logs) and stores them for a user-defined retention period. This enables you to restore your database to any point in time within that retention period.

• Database Snapshots: You can create or restore from user-initiated snapshots of your DB instance. These snapshots are kept until you explicitly delete them.

• Scalability: Amazon RDS allows you to scale your database's computing and storage resources with minimal downtime. Several scaling methods are available, including vertically increasing instance sizes and adding read replicas.

• Read Replicas: Enhance the performance of read-heavy database workloads by creating one or more read replicas of a source DB instance in the same or different geographical region.

• Multi-AZ Deployments for High Availability: Automatically provision and maintain a synchronous standby replica in a different Availability Zone. In the event of planned or unplanned outages, Amazon RDS automatically fails over to the standby so that database operations can resume quickly without administrative intervention.
