Josh Long is a very knowledgeable person to hear talk about Spring. He has published a few books on Spring and is a committer on several Spring projects. Having watch recordings with Josh before I thought it would be good to check out his presentation entitled, “Building “Bootiful” Microservices with Spring Boot.” He has a good sense of humor and even his title is trying to give us a grin.
Microservices vs Monolithic
Josh begins by starting out this presentation detailing the Microservices vs Monolithic conversation that has been going on for many years. He shows us an email from 1992 from Ken Thompson discussing this very issue in regards to Linux. Josh points out some of the issues we see when we have a monolithic architecture. We add on another layer and we increase the complexity of the project. As I have been a developer for fifteen years I have seen some large codebases that will confuse the most adept programmer. Another issue is the code “on-ramp” or learning curve can be quite steep and we can be unsure where to start our work for a modification.
Elegant approach to use Microservices
One of the benefits of using the Microservices approach is to have single focused loosely coupled tools that can scale better. One example Josh cites is Netflix, that uses Spring Boot extensively. He also described how Netflix has collaborated on Spring Boot to improve many aspects of it. He also suggest we can take our monolithic applications and “tease out” microservice applications. Josh talks about how Ticketmaster has leveraged this Microservice design to give them what Rod Barlow a senior technologist calls, “Boardroom agility or the process of quickly reacting to the marketplace.” This design approach has come to be a competitive advantage.
