AWS Global Infrastructure

The infrastructure of AWS contains regions, availability zones, data centers, edge locations, or points of presence.

AWS Regions

AWS Regions

How to choose an AWS region?

If you want to launch a new application, then you should consider the below parameters to choose a region:

  • Compliance with data governance and legal requirements: Data never leaves a region without your explicit permission.
  • Proximity to customers: Reduced latency.
  • Available services within a Region: New services and new features aren’t available in every region.
  • Pricing: Pricing varies from region to region and is transparent on the service pricing page.

 AWS Availability Zones

Each region has many availability zones (usually 3, min is 2, max is 6). Example:  ap-southeast-2a, ap-southeast-2b, ap-southeast-2c etc. Each availability zone (AZ) is one or more discrete data centers with redundant power, networking, and connectivity. They’re separate from each other so that they’re isolated from disasters. They’re connected with high bandwidth, ultra-low latency networking.

AWS Points of Presence (Edge Locations)

Amazon has 216 Points of Presence (205 Edge Locations & 11 Regional Caches) in 84 cities across 42 countries. Content is delivered to end-users with lower latency.

Ket Takeaway

AWS is actively offering 200 services around various geographical locations across the world. AWS local zones are connected to the parent region via Amazon’s redundant to manage regions and connected locations for convenient services to the end-users. If you are looking for a helping hand to leverage AWS global network to deploy your app to multiple AWS regions at a single click, then we can be your one-stop solution.
