Chris Richardson is a developer and architect. Java Champion.

Chris Richardson is a developer and architect. He is a Java Champion, a JavaOne rock star and the author of POJOs in Action, which describes how to build enterprise Java applications with frameworks such as Spring and Hibernate. Chris was also the founder of the original, an early Java PaaS for Amazon EC2. Today, he is a recognized thought leader in microservices and speaks regularly at international conferences. Chris is the creator of, a pattern language for microservices, and is writing the book Microservice Patterns, which is available at Manning. He provides microservices consulting and training to organizations that are adopting the microservice architecture and is working on his third startup Eventuate, an application platform for developing transactional microservices.

Workshop: Developing Microservices – Enable the rapid and safe delivery of software through functional decomposition

Enterprises need to deliver better software faster. It’s no longer sufficient to release quarterly or even monthly. Instead, organizations must use methods, such as DevOps, to frequently deploy changes into production, perhaps as often as multiple times per day. One obstacle, however, to DevOps-style development is that organizations are often mired in monolithic hell. Key business applications are large, complex, unwieldy monoliths, and so it’s impossible to rapidly and safely deploy changes.

The solution is to adopt the microservice architecture, which is an architectural style that has the testability and deployability necessary for DevOps. In this workshop, you will, through a combination of lectures and discussions, learn how to use the microservice architecture to develop your applications. We will describe how to solve some of the key obstacles you will face including distributed data management. You will learn about strategies for refactoring a monolith to a microservice architecture.

Course Outline:

Overview of the microservice architecture

  • The microservice architecture as an architectural style
  • Benefits and drawbacks of microservices
  • The microservice pattern language
  • Decomposition

Overview of decomposition

  • Decompose by business capabilities
  • Decompose by bounded context
  • Service design guidelines

Managing distributed data in a microservice architecture data consistency

  • Overview
  • Maintaining consistency using sagas
  • Using event sourcing
  • Querying using the API composition and CQRS patterns
  • Using the CQRS pattern

Testing strategies

  • Introduction to the testing pyramid
  • Writing consumer-driven contract tests
  • Developing component tests
  • Developing end to end tests


  • Incrementally refactoring a monolith into microservices
  • Strategy #1: stop digging
  • Strategy #2: split front-end & backend
  • Strategy #3: extract services
