The video tutorial explains the traditional method of deploying Java applications, which involved multiple complex steps like installing Java and a web server. It contrasts this with the simplicity offered by Spring Boot, which uses embedded servers to streamline the process. The tutorial demonstrates how to build and run a JAR file containing an embedded server, specifically Tomcat, and discusses the benefits of using JAR files over WAR files. It also introduces Spring Boot starters for different embedded servers like Jetty and Undertow.
