Aurora Global Database

Aurora Global Database — Low-Latency Global Replication

Aurora Global Database replicates your database across up to 5 AWS regions with typical replication lag under 1 second. It enables globally distributed applications to read from local regions and write to a primary region.

Architecture

Primary Region (us-east-1):
  Aurora Cluster with 1 Primary + up to 15 Read Replicas
  ALL WRITES go here
  Replication lag: 0ms

Secondary Region 1 (eu-west-1):
  Aurora Cluster with up to 15 Read Replicas
  READS ONLY from here (from local apps)
  Replication lag: typically < 1 second

Secondary Region 2 (ap-southeast-1):
  Same as above

All secondary clusters replicate from primary
via dedicated AWS network infrastructure
(not through the public internet)

Cross-Region Reads

# Application configuration:
# Write endpoint: aurora-global.cluster-xxx.us-east-1.rds.amazonaws.com
# Read endpoint (EU users): aurora-global.cluster-xxx.eu-west-1.rds.amazonaws.com

# Route 53 geolocation routing:
# EU users --> EU read endpoint (< 10ms)
# US users --> US primary (reads) or read replica
# APAC users --> APAC read endpoint

Managed Failover — Disaster Recovery

If the primary region fails, any secondary region can be promoted to primary in under 1 minute with minimal data loss (typically under 1 second of transactions).
