Availability Zones (AZs) are isolated sets of resources within a region, each with redundant power, networking, and connectivity, housed in separate facilities. Each Availability Zone is isolated, but the Availability Zones in a Region are connected through low-latency links. AWS provides you with the flexibility to place instances and store data across multiple Availability Zones within each AWS Region for high resiliency. |
