title: Where and how to deploy a Java Spring Boot application for free?
body: <p>I want to know where and how can I deploy a Java web application made with Spring Boot or an app built with servlets or JSP.</p>
  <p>Consider me a beginner in this topic. If you have suggestions about what I should learn first in order to accomplish this then please share, also if you have any links to particularly helpful blogs or videos that will do too.</p>
  <p>Thank you all in advance.</p>
