When creating a RDS instance, the user is asked if they would like to use a Multi-AZ RDS instance. Multi-AZ RDS instances are optional and have a cost associated with them. In the event of planned database maintenance or unplanned service disruption, Amazon RDS automatically fails over to the up-to-date standby, allowing database operations to resume without administrative intervention. Multi-AZ deployments aim to provide enhanced availability and data durability for MySQL, MariaDB, Oracle, PostgreSQL and SQL Server instances and are targeted for production environments. Multi-AZ database instance can be developed at creation time or modified to run as a Multi-AZ deployment later. Amazon RDS Multi-Availability Zone (AZ) allows users to automatically provision and maintain a synchronous physical or logical "standby" replica, depending on database engine, in a different Availability Zone (independent infrastructure in a physically separate location).
In May 2010 Amazon announced Multi-Availability Zone deployment support.
Amazon RDS offers different features to support different use cases. New database instances can be launched from the AWS Management Console or using the Amazon RDS APIs. In March 2019 AWS announced support of PostgreSQL 11 in RDS, five months after official release. In November 2014 AWS announced Amazon Aurora, a MySQL-compatible database offering enhanced high availability and performance, and in October 2017 a PostgreSQL-compatible database offering was launched. This was followed by support for Oracle Database in June 2011, Microsoft SQL Server in May 2012, PostgreSQL in November 2013, and MariaDB (a fork of MySQL) in October 2015, and an additional 80 features during 2017. Timeline Īmazon RDS was first released on 22 October 2009, supporting MySQL databases. AWS does not offer an SSH connection to the underlying virtual machine as part of the managed service. Scaling storage and compute resources can be performed by a single API call to the AWS control plane on-demand. Administration processes like patching the database software, backing up databases and enabling point-in-time recovery are managed automatically. It is a web service running "in the cloud" designed to simplify the setup, operation, and scaling of a relational database for use in applications.

You can host it on Aurora which will enhance the benefits of having a serverless backend because AWS manages Aurora and it will scale automatically.Īurora does not have a free quota and therefore you will have to pay for its usage.
