Global Network

Performance is a key driver of the design of the AWS global infrastructure. AWS has the largest global infrastructure footprint of any cloud provider, and this footprint is expanding continuously to help customers deliver better end-user experiences, rapidly expand operations to virtually any region or country, and to meet their data locality and sovereignty requirements. If a business wishes to serve its customers in Europe, the customer should be able to choose from a broad selection of regions or data centers in Europe such as Paris, London, Frankfurt or Dublin to deliver the best possible customer experience.

Global Infrastructure

Every data center, AZ, and AWS Region is interconnected via a purpose-built, highly available, and low-latency private global network infrastructure. The network is built on a global, fully redundant, parallel 100 GbE metro fiber network that is linked via trans-oceanic cables across the Atlantic, Pacific, and Indian Oceans, as well as the Mediterranean, Red Sea, and South China Seas.

High Performance

Availability Zones (AZs) give customers the ability to operate production applications and databases that are more highly available, fault tolerant, and scalable than would be possible from a single data center. AWS maintains 77 AZs around the world and we continue to add at a fast pace. Each AZ can be multiple data centers, and at full scale can be hundreds of thousands of servers. They are fully isolated partitions of the AWS Global Infrastructure. With their own power infrastructure, the AZs are physically separated by a meaningful distance, many kilometers, from any other AZ.

Flexible, global footprint

All Availability Zones (AZs) are interconnected with high-bandwidth, low-latency networking, over fully redundant, dedicated metro fiber providing high-throughput, low-latency networking between AZs. AZs are also powerful tools for helping build highly available applications. AZs make partitioning applications about as easy as it can be. If an application is partitioned across AZs, companies are better isolated and protected from issues such as lightning strikes, tornados, earthquakes and more.
