Multi-region Systems

What is this?

Multi-region systems run active or standby workloads in more than one AWS Region for latency, compliance, or disaster recovery.

Why should you care?

AwsVerse serves EU customers from eu-west-1 and India from ap-south-1 with Route 53 latency routing.

See it live — copy this example

Run in AWS CloudShell / local AWS CLI v2, or follow the matching steps in the AWS Console (Free Tier).

aws route53profiles associate-resource-to-profile \
  --profile-id rp-abc123 \
  --resource-arn arn:aws:route53:us-east-1::hostedzone/Z123 \
  --name awsverse-global-dns

What happened?

Associates hosted zone with Route 53 profile for multi-account DNS management.
Pair with latency-based records to nearest healthy region.

Practice next

Deploy read-only stack in second region.
Replicate S3 with CRR; Aurora global DB for RPO.
Route 53 latency records to both ALBs.
Run game day failing over primary region.
Compare active-active DynamoDB global tables.

Remember

Multi-region for DR and latency. Replicate data with defined RPO. Route 53 steers users to nearest.

AwsVerse EU expansion

GDPR requires EU data residency.

Outcome: eu-west-1 stack serves EU users; data never leaves region.
