AWS Security Concepts
Region
AWS has data centers in different areas of the world.
Amazon regions:
- Asia Pacific (Tokyo) ap-northeast-1
- Asia Pacific (Singapore) ap-southeast-1
- Asia Pacific (Sydney) ap-southeast-2,
- EU (Frankfurt) eu-central-1
- EU (Ireland) eu-west-1
- South America (Sao Paulo) sa-east-1
- US East (N. Virginia) us-east-1
- US West (N. California) us-west-1
- US West (Oregon) us-west-2
This is how it can be configured:
Availability Zones
An availability zone is a distinct location within a region engineered to be isolated from failures in other availability zones. Think about it as location: by placing resources in different availability zones you can protect the application from the failure of a single location. Each region provides low-latency network connectivity with other zones within the same region. Example of availability zones within a region: us-west-2b.
The list of zones and their codes is available here:
An auto-scaling group can span multiple availability zones.
Availability zone operations:
Availability zones play an essential role in how subnets are used in a VPC.
Amazon Resource Name (ARN)

AWS Service
As part of a service configuration, the user may be in the situation to pass an IAM role to the service.
Services:
AWS Types
