Developer need not to worry about the underlying infrastructure, all he/she has to look into is the services running on them and the stack they write. You do not have to worry about where your code is running. Which leads to faster rollouts, faster releases, faster deployments. Even rollbacks have become piece of cake with having docker on your infrastructure. If there is any change in your service all you have to do is change the YAML (yet another markup language) file and you will have a completely new service in minutes.  Docker was build for scalabilty and high availability. It is very easy to load balance your services in docker, scale up and scale down as per your requirements.  The most basic application that is demoed by docker, is the following cat and dog polling polygot application. Each part of this application will be written and maintained by a different team. Add it will just get collaborated by docker. The above are the compone...
