The RDS Aurora MySQL/PostgreSQL capabilities of AWS extend the High Availability (HA) capabilities of RDS read replicas and Multi-AZ. In this presentation I discuss the different capabilities and HA configurations with RDS Aurora including:
- RDS Aurora Cluster single instance
- RDS Aurora Cluster multiple instances (writer + 1 or more readers)
- RDS Aurora Cluster multi-master
- RDS Aurora Global Cluster
- RDS Aurora Cluster options for multi-regions
Each option has its relative merits and limitations. Each will depend on your business requirements, global needs and budget.
