AWS Global Infrastructure

Amazon Web Services (AWS) has a global infrastructure that allows customers to access its services from multiple locations around the world. The AWS global infrastructure is made up of:

  • Regions: Each region is a separate geographic area, and it contains multiple availability zones (AZs). Each region is completely independent and isolated from other regions, and it has its own power, cooling, and physical security.
  • Availability Zones (AZs): Each AZ is one or more discrete data centers, with redundant power, networking, and cooling.
  • Edge locations: These are locations that are used for caching content for CloudFront, Amazon CloudFront, and Amazon Route 53.

AWS currently operates in more than 190 countries and territories. As of September 2021, there are 69 availability zones across 24 geographical regions globally. These are located in the US, Canada, South America, Europe, Africa, Asia, and Australia.

AWS customers can choose to run their applications and data in any region, and they can replicate their data across multiple regions for added redundancy and disaster recovery. This infrastructure allows customers to run their applications and services closer to their end-users, which can help to improve performance and reduce latency.

AWS also offers a number of services that allow customers to easily connect their on-premises infrastructure to the AWS cloud, such as AWS Direct Connect, VPN and AWS Outpost, which is AWS infrastructure on-premises.
