Introduction
When we think about AWS resources, questions naturally arise: Where are these resources located? How do they interact? How are they stored, and where can we deploy our services? Let’s explore the structure of AWS and see how everything is organized.
Data Centers: The Foundation
AWS data centers are secure facilities where physical servers and networking equipment reside. Each data center is equipped with redundant power, networking, and cooling, ensuring optimal performance and uptime. These data centers are the building blocks of AWS infrastructure, hosting the servers and storage that power AWS services.
Availability Zones (AZs): Ensuring Resilience
An Availability Zone (AZ) is a collection of data centers within a specific Region, separated by significant distances to reduce the likelihood of simultaneous outages. Each AZ is isolated yet connected to other AZs in the Region through low-latency links. This setup allows you to replicate workloads across AZs, enhancing fault tolerance and availability. We call them AZs because of high availability. There are currently 108 availability zones all around the world.
Regions: Global Coverage
AWS Regions are geographically separate areas that contain multiple AZs. Each Region operates independently, which allows AWS customers to choose where their applications and data are hosted based on factors like latency, compliance, and resilience needs. With Regions across North America, Europe, Asia-Pacific, and more, AWS offers global reach for customers around the world. There are currently 34 launched regions.
Edge Locations: Low-Latency Content Delivery
Edge locations are smaller, globally distributed data centers that AWS uses for caching content and reducing latency through Amazon CloudFront. When users request data, they are often directed to the nearest edge location, ensuring faster content delivery. This is especially useful for services like video streaming, websites, and gaming. There are more than 600 POPs all around the globe.

Local Zones: Extending AWS Closer to Users
Local Zones bring AWS services closer to specific metro areas, offering low-latency access for applications that require it, such as gaming, media production, and machine learning. They allow customers to run latency-sensitive applications closer to their end users while still benefiting from AWS’s extensive services. There are currently 41 local zones.

AWS Wavelength: Ultra- Low Latency for 5G Applications
AWS Wavelength is designed to bring AWS compute and storage services closer to users on mobile devices by embedding AWS infrastructure within telecommunications providers’ 5G networks. This setup enables ultra-low latency for applications like gaming, augmented reality (AR), virtual reality (VR), and IoT.
AWS Outposts: Bringing AWS to Your Data Center
AWS Outposts is a fully managed service that extends AWS infrastructure, services, and tools to your on-premises data center or co-location space. It provides a truly hybrid cloud experience by enabling companies to run AWS services locally while seamlessly integrating with the rest of their AWS environment.
Conclusion
AWS’s global infrastructure is designed for reliability, performance, and scalability, offering a range of options to optimize workload placement. Whether it’s Regions for global coverage, AZs for resilience, or Edge Locations for low latency, AWS enables customers to deploy applications wherever they need them.
