Docker has given a different perception to application development and their run time environment. Containerization of application is very much essential now a days. Think about you have two different application in production server at same time and those applications are developed in PHP 7.2 and PHP 5.6 respectively. Now you can imagine how much trouble it could be to manage two different PHP version.
If you were using Docker, you could simply spin up another container, set the PHP version to 5.6 and put it right next to your other container that has PHP version 7.2 on it, running on the same server with no problems whatsoever. That flexibility, portability and the option to more efficiently use your server resources are what make Docker so compelling to use.

The concurrent program application short name, the concurrent program short name, and the concurrent request parameters are all available to the MLS function to determine the list of languages that the request should be run in.Read More
