Fast Deployment:

Another advantage of using Docker containers is that it helps in reducing deployment time. Usually setting up hardware and infrastructure for running apps takes time. However, by using Docker a developer can easily and quickly deploy an app without the need of setting up new hardware and infrastructure which might take lots of time.

So, if you are a developer then make sure that you use Docker containers it will make your work easier and you would be able to do your work more proficiently and quickly.

Agility:

Using containers, you can easily make the development process of an app agile/responsive. The containers are highly portable and offer many other advantages to their users which make the development process quicker/agile and responsive. Besides this, you can also use them with services/platforms like Amazon Web Services, Azure, Google Compute Platform, etc. So, make sure you use containers to make the development process of an app agile and responsive.

Security:

Another great benefit of using containers is that they are highly secure. Docker makes sure that each app that is running in a container is completely separate/isolated from other apps. No container can look inside other containers and the processes that are running inside it. Thus, it is right to say Docker containers are very secure and reliable in comparison to virtual machines.
