AWS Regions and Availability Zones & Edge Locations

AWS Regions and Availability Zones

What are Regions  & AZ?

It is a physical location around the world where aws has cluster data centers. 

AWS call each group of logical data centers an Availability Zone. 

Each AWS Region consists of a minimum of three, isolated, and physically separate AZs within a geographic area. Unlike other cloud providers, who often define a region as a single data center, the multiple AZ design of every AWS Region offers advantages for customers. 

Each AZ has independent power, cooling, and physical security and is connected via redundant, ultra-low-latency networks. AWS customers focused on high availability can design their applications to run in multiple AZs to achieve even greater fault-tolerance. AWS infrastructure Regions meet the highest levels of security, compliance, and data protection.

AWS provides a more extensive global footprint than any other cloud provider, and to support its global footprint and ensure customers are served across the world, AWS opens new Regions rapidly. AWS maintains multiple geographic Regions, including Regions in North America, South America, Europe, China, Asia Pacific, South Africa, and the Middle East. 

Edge Locations

Edge locations are AWS data centers designed to deliver services with the lowest latency possible.

What is AWS edge locations vs availability zones?

Both the Edge Locations (EL) and Availability Zones (AZ) are AWS Data Centers, but EL are primarily used for caching of the data to provide better user experience with low latency, the AZ are used for hosting servers, websites, applications, softwares, Big Data processing, analytics and a wide variety of use cases
