Spring Boot makes it easier to create Spring applications by auto-configuring the Spring Framework based on dependencies and automatically embedding an HTTP server like Tomcat, avoiding complex setup and configuration. It also provides developer tools, application monitoring endpoints, and the ability to create profiles for different environments and customize application properties.
