Our node application can be deployed on a hosting platform like Microsoft Azure, AWS or Heroku. Before the deployment, it needs to be encapsulated using Docker. 

Docker and Deployment Operations is out of the scope of Automation Testing course therefore is it not covered here, however, the knowledge of Docker and Deployment Operations is directly applicable to Jenkins, since the entire operation of creating a Docker container and deploying it on a platform can be performed through a command line window, hence we can do it through Jenkins, by simply chaining the relevant deployment commands.
