![]() ![]() AWS maintains multiple geographic Regions, including Regions in North America, South America, Europe, China, Asia Pacific, South Africa, and the Middle East.Īn Availability Zone (AZ) is one or more discrete data centers with redundant power, networking, and connectivity in an AWS Region. AWS infrastructure Regions meet the highest levels of security, compliance, and data protection.ĪWS 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 customers focused on high availability can design their applications to run in multiple AZs to achieve even greater fault-tolerance. Each AZ has independent power, cooling, and physical security and is connected via redundant, ultra-low-latency networks. 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 AWS Region consists of multiple, isolated, and physically separate AZs within a geographic area. We call each group of logical data centers an Availability Zone. AWS has the concept of a Region, which is a physical location around the world where we cluster data centers. ![]()
