AWS Global Infrastructure

Global Infrastructure (amazon.com)

AWS Global infrastructure consists of Regions, Availability zone, Local Zones, Wavelength Zone, and Outposts.

  • Regions: AWS region is a cluster of 3 or more availability zones. each region provides the highest level of security. At present, there are 30 Launched regions across the world that are interconnected. Global Infrastructure Regions & AZs (amazon.com)

  • Availability Zone: Availability zones consist of 1 or more data centers. Each datacenter is connected with a redundant power supply and network connectivity. When businesses are looking for highly available infrastructure, they can deploy it into multiple availability zones. AWS Resource Access Manager (amazon.com)

  • Edge Location:

  • A site that CloudFront uses to cache copies of your content for faster delivery to users at any location. Mainly edge location is used to host the web content (Static or Dynamic) it may be in the form of Cache or the uploaded one by a user. Edge locations are also a type of datacenter, But they are optimized to cache content for improved static content delivery.

  • AWS Local Zone: AWS Local Zones place compute, storage, database, and other AWS services closer to its end-users. We can use highly-demanding applications that require single-digit millisecond latencies for your end-users such as media & entertainment content creation, real-time gaming, reservoir simulations, electronic design automation, and machine learning.

  • Regional Edge Location - Located between Origin server and edge location. when data is requested at the Edge Location that is no longer available, the Edge Location can retrieve the cached data from the Regional Edge Cache instead of the Origin servers, which would have a higher latency.

AWS Wavelength: AWS Wavelength enables developers to build applications that deliver single-digit millisecond latencies to mobile devices and end-users. AWS developers can deploy their applications to Wavelength Zones, AWS infrastructure deployments that embed AWS compute and storage services within the telecommunications providers’ datacenters at the edge of the 5G networks, and seamlessly access the breadth of AWS services.

AWS Outposts: AWS Outposts is a family of fully managed solutions delivering AWS infrastructure and services to virtually any on-premises or edge location for a truly consistent hybrid experience. Outposts solutions allow you to extend and run native AWS services on premises.

Selecting a Region: Selecting a Region for service, data, application


1. Legal Requirements & Government Policy

2. Geo Proximity to users. Latency

3. Service Available with in a Region

4. Cost

As we have seen different infrastructures, we can use services from other regions if it is not available in your local region. to use Services from another region we need to consider business compliance.
