Microservice Architecture
Supported by KongWelcome to the first of what is hopefully a regular roundup of what’s new and relevant in the world of microservices. In the past week:
-
Russ Miles (@russmiles) announced µCon, the first conference about microservices. It takes place in London on November 27th-28th.
-
Martin Fowler (@martinfowler) published the final installments of his in-depth article about microservices.
-
Arnon Rotem-Gal-Oz compared microservices with SOA and argued that “microservices” is not a good term.
-
Gawain Hammond (@gawainhammond) wrote a blog post on microservices defending the term “microservices”.
-
@rrees wrote in interesting summary of a session on microservices at the Scale Summit.
-
Chris Richardson (@crichardson) published Thoughts about #microservices – less micro, more service? that suggested that there should be more emphasis on “service” and less on “micro”.
-
There was also the ongoing twitter discussion.
And then there was this:

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 RPPPOGHM to sign up for $95 (valid until March 26th, 2025). There are deeper discounts for buying multiple seats.
Learn how to create a service template and microservice chassis
Take a look at my Manning LiveProject that teaches you how to develop a service template and microservice chassis.
BUILD microservices
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.
