AWS Global Infrastructure

AWS serves millions of customers worldwide using a massive global footprint.

Key Components:

  • Regions: Physical locations around the world where AWS clusters data centers. Each region is independent.
  • Availability Zones (AZs): One or more discrete data centers with redundant power, networking, and connectivity in an AWS Region.
  • Edge Locations: Endpoints for AWS which are used for caching content (CloudFront).

Choosing a Region:

When picking a region, consider:

  1. Compliance: Data residency requirements.
  2. Proximity: Reduce latency for users.
  3. Available Services: Not all services are in all regions.
  4. Pricing: Costs vary by region.
