Sam Newman on moving from monolith systems to microservices - a podcast by OReilly Media

The O’Reilly Programming Podcast: Principles for the successful adoption of microservices.

In this episode of theO’Reilly Programming Podcast, I talk about microservices withSam Newman, presenter of the O’Reilly video courseThe Principles of Microservicesand the online training courseFrom Monolith to Microservices. He is also the author of the bookBuilding Microservices: Designing Fine-Grained Systems.

Discussion points:

• For organizations considering migrating from monolith systems to microservices, Neman suggests moving gradually, by starting with one or two services at the beginning, getting them deployed, and assessing the outcome.
• Newman identifies independent deployability as one of the key principles for doing microservices well. “If you create a system architecture with independent deployability, so many benefits flow from that,” he says.
• He recommends a “consumers first” focus for microservices, with designs based on how software will be implemented by customers.
• How microservices can enable cost-effective scaling
• In discussing modularity, Newman says “If you want to look at a system that gets modules right, look atErlang, which was built from the ground up to be a language and a runtime for building distributed systems.”
