Availability

Managed with Availability Zones and Regions.

Considerations

• Compliance - legal requirements on where you run your service.
• Latency - how close are your servers to your users.
• Pricing - prices varies from region to region
• Service Availability - not all services are available in all regions

Services

Depending on the service are deployed at either

• Availability Zone level
• Region level
• Global level

Region-scoped services generally have high durability and availability provided by AWS.

AZ-scoped services require the user to provide this durability and availability.
