The AWS Cloud operates 43 Availability Zones within 16 geographic Regions around the world, with announced plans for eight more Availability Zones and three more Regions.
The AWS Cloud infrastructure is built around Regions and Availability Zones (“AZs”). A Region is a physical location in the world where we have multiple Availability Zones. Availability Zones consist of one or more discrete data centers, each with redundant power, networking and connectivity, housed in separate facilities. These Availability Zones offer you the ability to operate production applications and databases which are more highly available, fault tolerant and scalable than would be possible from a single data center. The AWS Cloud operates 43 Availability Zones within 16 geographic Regions around the world.

Unlike virtually every other technology infrastructure provider, each AWS Region has multiple Availability Zones and data centers. As we’ve learned from running the leading cloud infrastructure technology platform since 2006, customers who care about the availability and performance of their applications want to deploy these applications across multiple Availability Zones in the same region for fault tolerance and low latency. Availability Zones are connected to each other with fast, private fiber-optic networking, enabling you to easily architect applications that automatically fail-over between Availability Zones without interruption.
In addition to replicating applications and data across multiple data centers in the same Region using Availability Zones, you can also choose to increase redundancy and fault tolerance further by replicating data between geographic Regions. You can do so using both private, high speed networking and public internet connections to provide an additional layer of business continuity, or to provide low latency access across the globe.
You retain complete control and ownership over the region in which your data is physically located, making it easy to meet regional compliance and data residency requirements.
The AWS Cloud has announced plans to expand with eight new Availability Zones in three new geographic Regions: Ningxia in China, Paris in France and Stockholm in Sweden.
