Breaking the monolith

The document discusses different patterns for breaking apart a monolithic application into microservices. The Big Bang pattern breaks everything up at once, which is not recommended and can be difficult without experience. The Strangler pattern rewrites the system slowly at the edges over years until the old system is replaced. The Hybrid pattern is similar but retains some functionality in the original monolith while integrating new microservices, which is the recommended approach.
Breaking the monolith
- 5. Big Bang! Breaking apart every single piece of an existing monolith into microservices, such that there’s a single cutover from one to the other. The Big Bang pattern isn’t recommended for most enterprises as a means of migrating, and most definitely not for those who aren’t experienced with microservices already.
- 6. Strangler pattern Rewrite an existing system by gradually creating a new system at the edges of the existing one. The new system slowly grows over several years, until the old system is strangled into nonexistence.
- 7. Hybrid pattern Similar to the Strangler but you never fully strangle the original monolith. You retain some functionality within a monolith and integrate that with new microservices. RECOMMENDED
