Resilience in Amazon Storage Gateway

The Amazon global infrastructure is built around Amazon Web Services Regions and Availability Zones.

An Amazon Web Services Region is a physical location around the world where data centers are clustered. Each group of logical data centers is called an Availability Zone (AZ). Each Amazon Web Services 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 Amazon Web Services Region offers distinct advantages. Each AZ has independent power, cooling, and physical security and is connected via redundant, ultra-low-latency networks. If your deployment requires a focus on high availability, you can configure services and resources to in multiple AZs to achieve greater fault-tolerance.

Amazon Web Services Regions meet the highest levels of infrastructure security, compliance, and data protection. All traffic between AZs is encrypted. The network performance is sufficient to accomplish synchronous replication between AZs. AZs make partitioning services and resources for high availability easy. If your deployment is partitioned across AZs, your resources are better isolated and protected from issues such as power outages, lightning strikes, tornadoes, earthquakes, and more. AZs are physically separated by a meaningful distance from any other AZ, although all are within 100 km (60 miles) of each other.

In addition to the Amazon global infrastructure, Storage Gateway supports VMware vSphere High Availability (VMware HA) to help protect storage workloads against hardware, hypervisor, or network failures. For more information, see Using VMware vSphere High Availability with Storage Gateway.
