Hi,

Let's see why Docker is so popular for deploying application in various environments.

**Why is Docker so dam popular among developers and businesses?**

That's a good question, and there tons of reasons of using Docker in enterprise environment. Docker is being used by developers for running their application in development and testing environment. With the popularity of Docker, it's easier for companies to move their tech stacks to it. Companies can use their servers effectively and deploy many applications on the same server, yet each application in separate secured environment.

If we see the work of server administrator then we will find that the administrator finds its very difficult to solve the issue of library dependency of each application being deployed on the server. Administrator can use Docker to package application in container along with their specific dependency and then run many applications on the same server. Docker makes life of Administrator much easier.

For business its much easier to run applications with different configuration on the available server resource which helps better utilization of their investment on servers. If new technology comes business manager ask their tech team to create new Docker environment and test it on the existing hardware without actually ordering new servers.

How does Docker differ from the other options of running containers?

There are just so many differences between Docker and other options of running containers, but Docker is most useful among them. Docker is dam popular among developers, administrators and business due to its features. Docker comes with all the tools necessary to deploy today?s applications without any security issues.

Docker is different from most other container management alternatives because it lets you run a container with specific flags (like --user, --group, --port, --container) and then it runs it in a completely isolated VM. That makes it perfect for deploying microservice apps within your own organizations without losing any security mechanism. You can run many Docker container on your sever till server resources are exhausted. So, you can better utilize servers in your enterprise.

You can actually run services inside containers!

The Docker container makes it easier to customize the image that runs some service. You have to simply write in a Dockerfile and include all the dependencies of your project, then ship it for running on the production or test sever.

You can setup your bare-metal computer with no virtualization services and then use Docker service to run many containerized application on it.

Also, Docker allows you to spin up containers for testing purposes and then roll them back to a running state when you're ready. This allows for testing purposes not possible with other methods of containers.

Docker is faster

Docker is faster and you can run your application fast using Docker container service.

Why is Docker faster?

Docker is faster because containers can run in a completely isolated virtual machine as opposed to the one virtual machine per physical server. The ability to do that allows you to run multiple servers on the same machine, and that speeds up a lot of things.
