Microservices have become the industry standard for building new applications and most modern operations tooling is designed for service-oriented architectures. While refactoring a large monolithic application into smaller services is desirable, it’s not always feasible or practical. Braze’s core platform, a monolithic Ruby application, handles so many features that it would take months or even years to do this safely. So how do you operate a monolith in a microservices world? In this session, I’ll share how the team at Braze developed a microservices approach to our monolith that lets us better utilize modern tools, increase developer velocity, and improve reliability.
