Cloud Region
A geographic area containing data centres where cloud providers offer services, affecting data residency, latency, and compliance.
In-Depth Explanation
A cloud region is a geographic location where a cloud provider operates data centres. Region selection affects application performance, data sovereignty compliance, and disaster recovery.
Australian cloud regions:
- AWS: Sydney (ap-southeast-2), Melbourne (ap-southeast-4)
- Azure: Australia East (NSW), Australia Central (Canberra), Australia Southeast (Victoria)
- Google Cloud: Sydney (australia-southeast1), Melbourne (australia-southeast2)
- Oracle Cloud: Sydney, Melbourne
Selection factors:
- Latency: Proximity to users (5-20ms local vs 150-250ms overseas)
- Data sovereignty: Australian regulations may require local storage
- Service availability: Not all services available in all regions
- Pricing: Australian regions cost 10-20% more than US
- Disaster recovery: Secondary region for business continuity
- Compliance: Industry-specific data residency requirements
Multi-region strategies:
- Active-active: Application in multiple regions simultaneously
- Active-passive: Primary region with standby secondary
- Data replication: Cross-region copies for disaster recovery
- Edge caching: CDN content at global edge locations
For most Australian businesses, the Sydney region is the primary choice. Melbourne provides additional geographic redundancy for disaster recovery.
Business Context
Choosing the correct cloud region ensures compliance with data sovereignty, minimises latency for Australian users, and enables robust disaster recovery.
