Decompose Your Monolith - Strategies for Migrating to Microservices

In September 2019, I gave a talk at Oracle Code One about how to refactor a monolithic application to microservices.


A typical mission-critical enterprise application is a large, complex monolith developed by a large team. Software delivery is usually slow, and the team struggles to keep up with the demands of the business. Consequently, many enterprise applications are good candidates to be migrated to the microservice architecture. But how do you know whether it makes sense to migrate to microservices and how to get there?

This session describes when you should consider migrating to microservices. You will learn strategies for migrating a monolith application to a microservice architecture. The presentation explains how to implement new functionality as services, and you will also learn how to incrementally break apart a monolith, one service at a time.
