Sam Newman: Monolith to Microservices

Today on the InfoQ Podcast, Wes Reisz talks with one of the thought leaders in Microservices, CI/CD, and Cloud -- Sam Newman. The podcast covers many of the topics, techniques, and patterns that Sam writes about in his latest book, Monolith to Microservices: Evolutionary Patterns to Transform Your Monolith. Topics covered in the podcast include understanding the problem you’re trying to solve, organizational/people changes when it comes to microservice architectures, database strategies for decomposing monolithic datastores, and why we’re seeing projects reverting from microservices to monoliths.

Why listen to this podcast:

- Fundamentally, microservices are distributed systems. Distributed systems have baggage (complexity) that comes along with them. The best way to deal with this complexity is not to address it. Try to solve the problem in other ways before choosing to take an organization to microservices.

- A common issue that large enterprises run into that might be a strong indicator for implementing microservices occurs when lots of developers are working on a given problem and they’re getting in each other’s way.

- A useful structure to follow with microservices is to make sure each service is owned by exactly one team. One team can own more than one service but having clear ownership of who owns a service helps in some of the operational challenges with microservices.

- A release train should be a stop in the journey towards continuous delivery. It’s not the destination. If you find that you can only release in a release train, you are likely building a distributed monolith.

- There are challenges of operating microservices when the end customer has to operate and manage it. These challenges are part of why we’re seeing projects move from microservices to process monoliths.
