Global Infrastructure
- The hierarchy (largest to smallest)
- Regions — separate geographic areas, each fully independent.
- Availability Zones — one or more discrete data centers within a Region.
- Edge Locations — hundreds of CDN and DNS points of presence worldwide.
- The extensions
- AWS Local Zones — Region capability placed in a metro area for single-digit-millisecond latency.
- AWS Wavelength — compute inside 5G carrier networks.
- AWS Outposts — AWS hardware in your own data center.
- Why it matters
- Deploy globally in minutes with no capital expenditure.
- Achieve High Availability within a Region (multi-AZ) and disaster recovery across Regions.
- Meet data sovereignty rules by choosing where data lives.
- Cost note
- Prices differ by Region. Data transfer between Regions costs more than within a Region; data transfer in is generally free.
