Global Network of Regions and Edge Locations
The AWS Cloud spans 55 Availability Zones within 18 geographic Regions and 1 Local Region around the world, with announced plans for 12 more Availability Zones and four more Regions in Bahrain, Hong Kong SAR, Sweden, and a second AWS GovCloud Region in the US.
AWS Regions and Availability Zones
The AWS Cloud infrastructure is built around Regions and Availability Zones (AZs). AWS Regions provide multiple, physically separated and isolated Availability Zones which are connected with low latency, high throughput, and highly redundant networking. These Availability Zones offer AWS customers an easier and more effective way to design and operate applications and databases, making them more highly available, fault tolerant, and scalable than traditional single datacenter infrastructures or multi-datacenter infrastructures. For customers who specifically need to replicate their data or applications over greater geographic distances, there are AWS Local Regions. An AWS Local Region is a single datacenter designed to complement an existing AWS Region. Like all AWS Regions, AWS Local Regions are completely isolated from other AWS Regions. The AWS Cloud spans 55 Availability Zones within 18 geographic Regions and one Local Region around the world.
High Availability Through Multiple Availability Zones
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.
Improving Continuity With Replication Between Regions
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.
Meeting Compliance and Data Residency Requirements
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 12 new Availability Zones in four new geographic Regions: Bahrain, Hong Kong SAR, Sweden, and a second AWS GovCloud Region in the US.
