This example demonstrates the basic building blocks for implementing event streaming by leveraging cloud-native services. As depicted in the diagram at the top of the pattern, a producer publishes events to the stream (AWS Kinesis) and stream processors (AWS Lambda) consume and process the events. The following is a fragment of an AWS CloudFormation resource from a Serverless Framework serverless.yml file. In Chapter 6, Deployment, we will discuss how this fits into a continuous integration and deployment pipeline. This demonstrates that provisioning a cloud-native event stream, such as AWS Kinesis, is completely declarative and boilerplate and thus has a very low barrier to entry.
