- AWS Regions are geographically isolated clusters of data centers.
- Named using a consistent format (e.g.,
us-east-1,eu-west-3).
- Most AWS services are region-scoped, operating only within the chosen Region.
Choosing an AWS Region
Key factors to consider:
- Compliance & Data Residency – Data stays within the Region unless explicitly moved, helping meet legal and regulatory requirements.
- Proximity to Users – Reduces latency and improves application performance.
- Service Availability – Some services are available only in specific Regions; new features often launch in select Regions first.
