Hello and welcome back to our #100DaysOfAWS series! In this second blog, we'll be exploring the AWS Global Infrastructure, a cornerstone of the AWS ecosystem. Before we begin working with AWS, we need to understand the AWS Global Infrastructure. AWS is a Cloud Computing platform which is available globally. The AWS Global infrastructure is built around Regions and Availability Zones. It is the most secure, extensive, and reliable cloud platform, offering over 200 fully featured services from data centers globally.
The following are the components that make up the AWS infrastructure:
Regions -
- A Region is a physical location in the world that provides multiple, physically separated, and isolated Availability Zones
- A region is a collection of data centers which are completely isolated from other regions.
- A region consists of more than two availability zones connected to each other through links.
- Example of AWS regions - us-east-1, eu-west-3…
Availability Zones -
- Availability Zones consist of one or more discrete data centers, each with redundant power, networking, connectivity, and are housed in separate facilities.
- Each region has many availability zones (usually 3, min is 2, max is 6).
- Availability Zones are separate from each other so that they are isolated from disasters. Each Availability Zone is designed as an independent failure zone.
- Availability Zones are connected with high-bandwidth, ultra-low latency networking to form a Region.
Point of Presence -
- AWS has 216 Points of Presence (205 Edge Locations & 11 Regional Caches) in 84 cities across 42 countries
Edge Locations -
- Edge locations are Content Delivery Network (CDN) endpoints for CloudFront.
- There are many more edge locations than regions. Currently there are over 200 edge locations.
- Edge locations are mainly located in most of the major cities to distribute the content to end users with reduced latency. For example, some user accesses your website from Singapore; then this request would be redirected to the edge location closest to Singapore where cached data can be read.

That's a wrap for this blog post in our #100DaysOfDevOps series!
I hope you found this exploration of AWS Global Infrastructure informative and that it enhances your understanding of the foundation on which AWS operates.
