AWS Region
AWS Region
A geographical area with multiple AWS data centers (Availability Zone) for fault tolerance.
Availability Zone (AZ)
Availability Zone (AZ)
A physically separate data centre within a Region, keeping services independent and resilient to failures. Each AZ has independent power, cooling, and networking.
Why Use Multiple Regions?
Why Use Multiple Regions?
Disaster Recovery. Data Sovereignty: Meet legal and compliance requirements for storing data within specific countries. Low Latency: reduce response time.

Study Notes
AWS Global Infrastructure
- AWS provides a global network of physical locations, including Regions, Availability Zones (AZs), and Edge Locations, for high availability, low latency, and fault tolerance.
AWS Regions
- A Region is a geographical area with multiple AWS data centers.
- Each Region has multiple isolated Availability Zones.
- Regions are physically separated for geographical redundancy.
- They offer services (e.g., EC2, S3, RDS) tailored to specific compliance and data sovereignty needs.
- Examples:
us-east-1(North Virginia),eu-west-1(Ireland). - Multiple Regions support disaster recovery, business continuity, data sovereignty, and low latency by serving customers closer to their location.
AWS Availability Zones (AZs)
- An AZ is a physically isolated data center within a Region.
- Each AZ has independent power, cooling, and networking.
- Connected by low-latency, high-speed private networks.
- Designed to prevent failures from spreading.
- Example: A Region like
us-east-1might have AZsus-east-1a,us-east-1b, andus-east-1c. - Using multiple AZs increases high availability and fault tolerance by distributing workloads across independent data centers.
Edge Locations
- Edge Locations are global content delivery network (CDN) endpoints for services like Amazon CloudFront.
- They cache data closer to end users to lower latency.
- Used by CloudFront, AWS Global Accelerator, and Route 53.
- Edge Locations are critical for faster content delivery, low-latency experiences, and scalable performance for applications with a global audience.
AWS Wavelength Zones
- AWS Wavelength runs AWS services within 5G mobile networks.
- This minimizes latency for applications like video streaming, gaming, and IoT, making it suitable for millisecond-level latency applications near mobile users.
AWS Local Zones
- AWS Local Zones extend AWS infrastructure to locations near population centers.
- They enable ultra-low latency workloads for applications requiring proximity to users or on-premises infrastructure.
- Suitable for latency-sensitive apps (e.g., video editing, real-time gaming, financial trading) and hybrid deployments.
Achieving High Availability with AWS
- High Availability ensures applications remain operational during failures.
- Use multiple AZs to distribute resources and avoid single points of failure. Load balancers are crucial for this purpose.
- Use multiple Regions to back up data and provide business continuity during regional outages. Cross-Region replication is often used here.
