Speed matters, and developers are challenged to reduce latency in their applications at every turn. In traditional synchronous programming patterns, users are asked to monitor the spinning wheel as the application moves from one task to the next until a response can be returned. However, developers can reclaim these precious milliseconds by learning to think asynchronously.

Asynchronous patterns challenge developers to evaluate what tasks require the client to wait versus what can be done after the fact. When developing serverless applications on AWS this process is made easier by the asynchronous and polling patterns that are native to AWS Lambda.

In this session I will demonstrate taking an existing translation application that is synchronous and modifying it to use asynchronous patterns. This will be accomplished using Amazon DynamoDB Streams and Amazon EventBridge.
