The monolithic solution has the following benefits:

• Simple to develop: Monolithic applications are very simple to develop because current development tools and IDEs support the development of monolithic applications
• Simple to test: As we have already discussed, monolithic applications have all of their modules in a single artifact, so you can easily carry out end-to-end testing by simply running the application either manually or with Selenium
• Simple to deploy: A monolithic application is a single artifact, so you can easily deploy it to the server as a WAR file
• Simple to scale: You can easily achieve scaling by copying the single artifact of the application to multiple running machines and setting up a load balancer behind the monolithic application

As you can see, monolithic applications have numerous benefits. They also have several disadvantages, which we will discuss shortly, but let's first have a look at the situations in which monolithic applications are useful.
