AWS: Relational Database Service – RDS

Relational Database Service also known as RDS is a collection of AWS services for managed relational databases.

We call the database as managed because AWS takes care of:

  • Scheduled automated backups

  • Simple Software Backups

  • Managed infrastructure for the database


If your database is hosted on EC2 then you have to figure out about database backups, data redundancy, and software patches.


But if your database is through RDS then AWS manages it all plus configuration is also easy. It also has ability to read replica.


RDS database options:

  • MySQL

  • MySQL server

  • PostgreSQL

  • MariaDB

  • Oracle DB

  • Amazon Aurora


RDS databases run on EC2 instances.


Advantages of RDS databases:

  • It makes easy to take snapshots.

  • It makes it easy to change the hardware and EC2 configuration as it backups the database.
