This document discusses using Concourse and Spring Cloud Contract for microservices delivery. It introduces microservices architecture challenges around build pipelines, testing, and environment provisioning. Consumer-driven contract testing is presented as a way to define contracts between services. The rest of the document demonstrates a Concourse pipeline for continuous delivery of a sample greeting microservices application using Spring Cloud Contracts.
