Training Services

Taught by Chris Richardson, an experienced software architect, author and serial entrepreneur.

Chris works with clients around the world helping them adopt the microservice architecture.

Chris also writes code regularly.


Virtual bootcamps:

Designing microservices: responsibilities, APIs and collaborations

When applying the microservice architecture pattern, the most important design decisions that you must make do not involve technology choices, such as Kubernetes vs. Serverless or REST vs. gRPC. Instead, what’s critical to your success is correctly identifying services, defining their responsibilities, APIs and collaborations. That’s because if you design your services badly, you risk creating a fragile, distributed monolith where every service is a potential point of failure, and services regularly change in lock step.

Through a combination of lectures, discussions, and kata exercises, Chris will walk you through distilling your application’s requirements into a collection of loosely coupled, appropriately-sized services.


Technology leaders, architects and experienced developers who want to learn how to design a microservice architecture. The architecture and design exercises are on paper and are independent of any particular technology stack.


This workshop is delivered as a mixture of online and offline activities:

  • online (e.g. Zoom) lectures, discussions, and kata reviews
  • offline kata exercises
