This has many advantages, but sometime… Is there a point if I'm doing a traditional enterprisey system? We can now observe that our fat jar is organized a bit differently from our previous war file: Without the plugin, the lib folder would not exist, and all the content of BOOT-INF/classes would be located in the root of the package.

This ensures that the relevant embedded container dependencies aren’t included in the WAR file.

I use Tomcat with a single application deployed as a war file for a few projects. With Spring Boot, this approach is inverted as the app server is directly in your JAR. However, a technology trend might bring it back in favor. Create the dockerfile. Clustering and load balancing are always handled the same way. So, it is not elective.

This plugin ships with lots of convenient features, such as: When we're working on a web application, we can leverage another very interesting feature of the Spring Boot Maven plugin: the ability to automatically deploy our web application in an embedded application server.

Spring Boot comes with two powerful plugins: They both essentially have feature parity and provide the ability to run Spring Boot apps from the command line as well as bundle up runnable JARs. Useing "containerless" tends to be easier because you can just have X instances running their own tomcat with a loadbalancer of your choice routing traffic. I see the benefit of bootstrapping for simple small projects (if you only have one small app, why bother with the maintenance overhead of the container server, etc). However, one compelling argument about Fat JARs is that since the booting technology is in charge of app management from the start, it can handle load classes in any way it wants. Imagine if any of those systems need to scale independently... spin up more batch processing consumers, or a couple extra rest servers or processes.

The more we move towards production, the more the conversation shifts towards stability and security. The canonical reference for building a production grade API with Spring. In this scenario, if there are 3 apps, you could put all of them on their own hardware, or all 3 on one box.
