AWS re:Invent 2017: Building Resilient, Multi-Region Serverless Applications (SRV313) – #AWS
Serverless computing already provides high availability and fault tolerance for your application by default. However, you can build serverless applications that are deployed across multiple regions in order to further increase your availability and fault tolerance. In this session, we show you how to architect a multi-region serverless application with Amazon API Gateway and AWS Lambda that can route end users to the appropriate region to achieve optimal latency or availability. Learn about the different options for running an active/active versus an active/passive multi-region setup, and the setup for failing over between regions.
