Microservice Architecture
Supported by KongA pattern language and visual notation for messaging systems: Enterprise integration patterns by @ghohpe and @bobby_woolf
One of the defining characteristics of the microservice architecture is that services are loosely coupled. Services should ideally be self-contained but some form of inter-service communication is inevitable. You should, however, be very careful about using synchronous calls (e.g. REST or gRPC) between services If you mimic the inter-module communication patterns in your monolithic you are likely to have a very brittle system due to the runtime coupling. To reduce runtime coupling, you should strive to use asynchronous messaging wherever possible.
My favorite book on asynchronous messaging is Enterprise Integration Patterns by Gregor Hohpe and Bobby Woolf. I bought it back in 2003, so I guess it’s a classic.
It’s a pattern language and visual notation for messaging systems.
I find it useful to describe an application’s architecture in terms of patterns such as Message Channel rather than immediately leaping into the technical details of today’s fashionable message broker. Later you can map that abstract architecture to an actual implementation. For example, take a look at the diagrams in my posts about orchestration-based and choreography-based sagas, such as the follow:
This is a must read book if you are building applications that use asynchronous messaging. You can learn more about the book and the pattern language on the book’s website.
About Microservices.io
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.
MICROSERVICES 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.

Virtual bootcamp: Distributed data patterns in a microservice architecture
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.
