Hello my lovely readers,
Hope you all are doing great! 🌟 Today marks the beginning of our 75-day AWS Solution Architect certification program, and we’re kicking off with a deep dive into the AWS Global Infrastructure. 🎉 As we follow the roadmap discussed in my previous blog, let’s explore this fundamental topic with some exciting details.
What is AWS Global Infrastructure? 🌐
AWS (Amazon Web Services) Global Infrastructure refers to the robust physical and network components that support AWS’s cloud services. This infrastructure is designed to ensure high availability, low latency, scalability, and reliability for users worldwide. Here’s a breakdown of its key elements:
1. Regions 🌎
AWS Regions are separate geographic areas housing AWS data centers. Each Region is isolated from the others to maximize fault tolerance and stability. By deploying applications closer to their end users, Regions help reduce latency and ensure data sovereignty. As of 2024, AWS boasts 33 Regions globally, with this number continually increasing.
2. Availability Zones (AZs) 🏢
An Availability Zone is a distinct location within a Region, built to be isolated from failures in other AZs. Each AZ consists of one or more data centers with independent power, cooling, and networking. This design enables applications to be highly available, fault-tolerant, and scalable by distributing resources across multiple AZs. The AWS Cloud currently spans 105 Availability Zones, with more on the horizon.
3. Edge Locations 📍
Edge Locations are data centers AWS uses to cache content and provide other services closer to users. Part of AWS’s Content Delivery Network (CDN), Amazon CloudFront, these locations reduce latency by caching copies of content near where requests are made.
