I gave this presentation at QConplus 2021. It illustrates how to design loosely coupled services using the problem of ordering burritos.
Here’s a burrito from one of my favorite restaurants:
Delivering large, complex software rapidly, frequently and reliably requires a loosely coupled organization. DevOps teams should rarely need to communicate and coordinate in order to get work done. Conway’s law states that an organization and the architecture that it develops mirror one another. Hence, a loosely coupled organization requires a loosely coupled architecture.
In this presentation, you will learn about design-time coupling in a microservice architecture and why it’s essential to minimize it. I describe how to design service APIs to reduce coupling. You will learn how to minimize design-time coupling by applying a version of the DRY principle. I describe how key microservices patterns potentially result in tight design time coupling and how to avoid it.
Here is an interview where I discussed this presentation.
You can find the video and transcript on the InfoQ website.
I provide consulting and training to help you use the microservice architecture effectively.
Microservices.io is brought to you by Chris Richardson. Experienced software architect, author of POJOs in Action, the creator of the original CloudFoundry.com, and the author of Microservices patterns.
Chris helps clients around the world adopt the microservice architecture through consulting engagements, and training workshops.
Chris teaches comprehensive workshops for architects and developers that will enable your organization use microservices effectively.
Avoid the pitfalls of adopting microservices and learn essential topics, such as service decomposition and design and how to refactor a monolith to microservices.
Learn moreChris offers numerous other resources for learning the microservice architecture.

Consider signing up for a two hour, highly focussed, consulting session.
My virtual bootcamp, distributed data patterns in a microservice architecture, is now open for enrollment!
It covers the key distributed data management patterns including Saga, API Composition, and CQRS.
It consists of video lectures, code labs, and a weekly ask-me-anything video conference repeated in multiple timezones.
The regular price is $395/person but use coupon MECNPWNR to sign up for $120 (valid until May 16th, 2023). There are deeper discounts for buying multiple seats.
Take a look at my Manning LiveProject that teaches you how to develop a service template and microservice chassis.
Engage Chris to create a microservices adoption roadmap and help you define your microservice architecture,
Use the Eventuate.io platform to tackle distributed data management challenges in your microservices architecture.
Eventuate is Chris's latest startup. It makes it easy to use the Saga pattern to manage transactions and the CQRS pattern to implement queries.
Engage Chris to conduct an architectural assessment.
