What are the key components of AWS Global Infrastructure?
AWS Regions – Geographically isolated locations hosting AWS services.
Availability Zones (AZs) – Multiple, isolated data centers within each region for redundancy.
Data Centers – Physical facilities housing AWS servers and storage.
Edge Locations / Points of Presence – Network endpoints for low-latency content delivery via Amazon CloudFront and Route 53.
What is an AWS Region and how is it structured?
AWS Regions are geographically distributed clusters of data centers.
Each region is identified by a code (e.g., us-east-1, eu-west-3).
Most AWS services are region-scoped, meaning resources are tied to a specific region.
What factors should you consider when choosing an AWS Region?
Consider the following factors:
Compliance with data governance and legal requirements:
Data never leaves a region without your explicit permission.
Proximity to customers:
Reduced latency for better performance.
Available services within a Region:
New services and features aren’t available in every Region.
Pricing:
Varies from region to region and is transparent on the AWS service pricing page.
What are AWS Availability Zones (AZs), and how are they structured within a region?
Each region has multiple Availability Zones (usually 3; min 3, max 6).
Example:
ap-southeast-2a
ap-southeast-2b
ap-southeast-2c
Each AZ is one or more discrete data centers with redundant power, networking, and connectivity.
AZs are physically separate from each other to remain isolated from disasters.
They are connected with high-bandwidth, ultra-low-latency networking.
What are AWS Points of Presence (Edge Locations), and what purpose do they serve?
Amazon has 400+ Points of Presence:
400+ Edge Locations
10+ Regional Edge Caches
Spread across 90+ cities in 40+ countries
Purpose: Deliver content to end users with lower latency by caching data closer to them.
What are AWS Points of Presence, and why are they important?
Amazon has 400+ Points of Presence (400+ Edge Locations & 10+ Regional Caches)
Present in 90+ cities across 40+ countries
Purpose: Deliver content to end users with lower latency
