wikipedia:Amazon Relational Database Service (or Amazon RDS) is a distributed relational database service by Amazon Web Services (AWS), also included in the AWS Free Tier option.

You can create different types of DBs using AWS web page or AWS CLI.

Regarding possible cost while learning AWS RDS, just be aware that you will be able to stop AWS RDS instances from AWS Management Console or AWS CLI for 7 days period at a time, but after those 7 days, it will be automatically started by AWS.[1] [2]

Timeline[edit]

Amazon RDS was first released on 22 October 2009, supporting MySQL databases.[3][4][5] This was followed by support for Oracle Database in June 2011,[6][7] Microsoft SQL Server in May 2012,[8] PostgreSQL in November 2013,[9] and MariaDB (a fork of MySQL) in October 2015,[10] and an additional 80 features during 2017.[11]

In November 2014 AWS announced Amazon Aurora, a MySQL-compatible database offering enhanced high availability and performance,[12] and in October 2017 a PostgreSQL-compatible database offering[13][11] was launched.[14]

In March 2019 AWS announced support of PostgreSQL 11 in RDS,[15] five months after official release.
