Microservice Architecture
Supported by KongWhat are microservices?
Microservices - also known as the microservice architecture - is an architectural style that structures an application as a collection of services that are
- Highly maintainable and testable
- Loosely coupled
- Independently deployable
- Organized around business capabilities
- Owned by a small team
The pattern language is your guide
The microservice architecture is not a silver bullet. It has several drawbacks. Moreover, when using this architecture there are numerous issues that you must address.
The microservice architecture pattern language is a collection of patterns for applying the microservice architecture. It has two goals:
- The pattern language enables you to decide whether microservices are a good fit for your application.
- The pattern language enables you to use the microservice architecture successfully.
A good starting point is the Monolithic Architecture pattern, which is the traditional architectural style that is still a good choice for many applications. It does, however, have numerous limitations and issues and so a better choice for large/complex applications is the Microservice architecture pattern.
Avoid the potholes
Thinking of migrating to the microservice architecture? If so, you should look at this presentation about the potholes in the road from monolithic hell and read this series of blog posts about anti-patterns and how to avoid them.
Assess your architecture
If you have built an application with the microservice architecture then take a look at the Microservices Assessment Platform. The platform assesses what you have built and identifies what needs to be improved. It reduce architectural and organizational risk and maximizes the benefits of the microservice architecture.

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 classes and workshops.
New 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 YRXRIEAS to sign up for $295 (valid until April 30th, 2021). There are deeper discounts for buying multiple seats.
LEARN about microservices
Chris offers numerous resources for learning the microservice architecture.
Training classes
Chris teaches comprehensive workshops, training classes and bootcamps for executives, architects and developers to help 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.
Delivered in-person and remotely.

Consulting services
Engage Chris to create a microservices adoption roadmap and help you define your microservice architecture,
The Eventuate platform
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.
