This Guidance helps customers design a resilient batch process application using AWS services. The batch application is deployed across two AWS Regions for automated failover and failback from one Region to another and leverages Amazon Simple Storage Service (Amazon S3) Multi-Region Access Points (MRAPs). With this architecture, you can obtain insights from your applications that help you make decisions on when to failover batch applications from a primary to a standby Region. While single-Region architectures are sufficient to support most customer's resilience requirements, the multi-Region architecture in this Guidance is ideal for customers with more demanding needs for resiliency.
