Amazon RDS
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:
- 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.
- 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.
