AWS Global infrastructure – Arkit

AWS (Amazon Web Services) is a cloud computing service provider that has a vast and extensive global infrastructure. AWS’s global infrastructure is composed of a network of data centers, edge locations, and points of presence (PoPs) located across various regions around the world. AWS’s global infrastructure provides a reliable, scalable, and highly available platform to run cloud-based applications and services.

Let’s dive into the details of AWS’s global infrastructure:

AWS Global infrastructure


AWS divides its global infrastructure into geographic regions, each consisting of multiple availability zones. As of September 2021, AWS has 25 regions globally, with 8 more planned for launch in the coming years. Each region has multiple data centers that are physically separated from each other but are connected through high-speed networking to provide low latency, high availability, and disaster recovery capabilities.

Each region is identified by a unique name, such as “us-east-1” or “ap-southeast-1,” and is completely independent of other regions. This means that data and resources created in one region are not automatically replicated in another region. However, AWS provides services like AWS Global Accelerator and Route 53 Global DNS that allow customers to distribute traffic across regions.

Availability Zones:

An availability zone (AZ) is a data center or cluster of data centers within a region. Each availability zone is a fully isolated unit with its power, networking, and connectivity. The isolation of AZs provides high availability and fault tolerance to AWS customers. In case of a failure or outage in one availability zone, other availability zones in the region can still operate normally.

Each region has a minimum of two availability zones, with some having as many as six. AWS customers can deploy their applications and services across multiple availability zones to achieve redundancy and fault tolerance.

Edge Locations:

AWS edge locations are data centers located in various parts of the world that serve as a content delivery network (CDN) for AWS services. Edge locations are not regions or availability zones but are distributed globally to provide low latency and high performance to AWS customers.

Edge locations are used to cache and deliver static and dynamic content, such as images, videos, and web pages, to end-users. AWS services like Amazon CloudFront, AWS Global Accelerator, and Amazon Route 53 DNS use edge locations to deliver content globally.

Points of Presence (PoPs):

AWS points of presence (PoPs) are network locations where AWS connects with other networks and internet service providers (ISPs) to improve the performance of AWS services. PoPs are similar to edge locations, but they do not store any data or content.

PoPs are strategically located in various cities and countries around the world, providing high-speed connectivity and low-latency routing for AWS customers. AWS services like Amazon Direct Connect and Amazon CloudFront use PoPs to improve the performance and reliability of their services.

In summary, AWS’s global infrastructure is composed of a vast network of data centers, availability zones, edge locations, and PoPs distributed globally. AWS’s global infrastructure provides customers with high availability, scalability, and low latency, making it an ideal platform for running cloud-based applications and services.
