description Amazon RDS Overview

Amazon Relational Database Service (RDS) simplifies the setup, operation, and scaling of traditional relational databases (like PostgreSQL, MySQL, and SQL Server). It handles tedious tasks such as patching, backups, and failover automatically, allowing developers to focus purely on schema and application logic. It is the default choice when ACID compliance and complex JOIN operations are mission-critical.

help Amazon RDS FAQ

Which database engines can Amazon RDS run?

Amazon RDS supports engines such as PostgreSQL, MySQL, MariaDB, Oracle Database, Microsoft SQL Server, and Amazon Aurora. The appeal is that AWS handles many operational chores around backups, patching, and failover.

When would someone choose Amazon RDS instead of DynamoDB?

RDS is for relational workloads that need SQL, joins, transactions, and familiar engines like PostgreSQL or MySQL. DynamoDB is a NoSQL service built for key-value and document-style access patterns at very high scale.

What does Multi-AZ mean in Amazon RDS?

Multi-AZ deployments keep a standby database instance in another Availability Zone for failover. It is mainly a high-availability feature, not a read-scaling feature like read replicas.

Does Amazon RDS remove the need for database administration?

It removes a lot of infrastructure work, including automated backups and managed patching, but it does not design schemas or tune bad queries for you. Teams still need to watch indexes, storage growth, connection limits, and engine-specific settings.
