Amazon RDS (Relational Database Service) is a collection of AWS managed services. Featuring several different popular relational database engines, including Aurora, Postgres, and MySQL, RDS is a popular choice for spinning up databases. One of the key features of RDS is that it is a cloud distributed product. This simplifies the setup of the databases and allows for easier scalability. There are a few features in particular that RDS is known for: 1. Read Replicas Read replicas create multiple “replica” copies of data. This allows high-volume applications to have enhanced performance for read-heavy operations. Read replica can be turned into standalone database instances, and elastically scale. 1. Multi-AZ AWS is well known for their availability zone architecture, which separates traffic from physical geographic regions. Multi-AZ settings allow for the creation of standby replicas in different regions to allow for enhanced performance. ## Amazon RDS Official Documentation https://aws.amazon.com/rds/ %% wiki footer: Please don't edit anything below this line %% ## This note in GitHub <span class="git-footer">[Edit In GitHub](https://github.dev/data-engineering-community/data-engineering-wiki/blob/main/Tools/Databases/Amazon%20RDS.md "git-hub-edit-note") | [Copy this note](https://raw.githubusercontent.com/data-engineering-community/data-engineering-wiki/main/Tools/Databases/Amazon%20RDS.md "git-hub-copy-note")</span> <span class="git-footer">Was this page helpful?
