Principles Of Microservices by Sam Newman

Microservices are small services with independent lifecycles that work together. There is an underlying tension in that definition – how independent can you be when you have to be part of a whole?

I’ve spent much of the last couple of years trying to understand how to find the right balance, and in this talk/tutorial I’ll be presenting the core seven principles that I think represent what makes microservices tick.

After a brief introduction of what microservices are and why they are important, we’ll spend the bulk of the time looking at the principles themselves:

  • Modelled Around Business Domain
  • Culture Of Automation
  • Hide Implementation Details
  • Decentralize All The Things!
  • Deploy Independently
  • Isolate Failure
  • Highly Observable

In terms of learning outcomes, I’d say that beginners will get a sense of what microservices are and what makes different, whereas more experienced practitioners will get an insight into practical advice into how to implement them.

Distributed systems have become more fine-grained in the past 10 years, shifting from code-heavy monolithic applications to smaller, self-contained microservices. But developing these systems brings its own set of headaches. With lots of examples and practical advice, this book takes a holistic view of the topics that system architects and administrators must consider when building, managing, and evolving microservice architectures.

Microservice technologies are moving quickly. Author Sam Newman provides you with a firm grounding in the concepts while diving into current solutions for modeling, integrating, testing, deploying, and monitoring your own autonomous services. You'll follow a fictional company throughout the book to learn how building a microservice architecture affects a single domain.
