Resilience in AWS AppSync - AWS AppSync

Resilience in AWS AppSync

The AWS global infrastructure is built around AWS Regions and Availability Zones. AWS Regions provide multiple physically separated and isolated Availability Zones, which are connected with low-latency, high-throughput, and highly redundant networking. With Availability Zones, you can design and operate applications and databases that automatically fail over between zones without interruption. Availability Zones are more highly available, fault tolerant, and scalable than traditional single or multiple data center infrastructures.

For more information about AWS Regions and Availability Zones, see AWS Global Infrastructure.

In addition to the AWS global infrastructure, AWS AppSync allows most resources to be defined using AWS CloudFormation templates; for an example of using AWS CloudFormation templates to declare AWS AppSync resources, see Practical use cases for AWS AppSync Pipeline Resolvers on the AWS blog and the AWS CloudFormation User Guide.
