• Faster than MySQL... Postgres
• Failover faster
• CRR: entire database is copied (not select tables)
• Load / Offload data directly from / to S3: efficient use of resources

• Support for Cross Region Replication as other RDS database

• Has Writer Endpoint and Reader Endpoint

• When the CPU usage increase, will add more DB to replicas, those DB will be registered into Reader Endpoint

• Once you use Custom Endpoint, then Reader endpoint is not used
• You can define other type of instance (db.r5.2xlarge...)
• You can combine multi cusotm endpoints

• Client has multi endpoints for DB Connection
• ONce one fail, it will do faster failover to another one

• Global Aurora is a new recommended way to do CRR
