A global application needs a relational database readable with low latency in three Regions, able to promote a secondary Region to full read-write within about a minute for regional DR. Which option fits?
A.RDS read replicas in each Region
RDS replicas have higher lag and slower, more manual promotion for regional DR.
B.Aurora Global Database
Correct. Aurora Global Database is designed for this exact pattern.
C.DynamoDB global tables
DynamoDB is NoSQL — the workload requires relational.
D.Redshift multi-region cluster
Redshift is an analytics warehouse, not an OLTP multi-Region store.
Why this answer
Aurora Global Database provides storage-level replication to secondary Regions (typically sub-second lag) and managed cross-Region promotion for DR — purpose-built for multi-Region relational low-latency reads plus fast failover.
