What is Docker?
Docker is a set of platform-as-a-service (PaaS) products that use OS-level virtualization to deliver software in packages called containers. Docker containers are analogous to physical containers that you use to store, package, and transport goods. But instead of these goods, they’re containers for software applications.
Docker configuration files are portable so other developers can clone the same development environment to work on the same piece of software without any issues like “this program doesn’t work on my system”.
How Is Docker Different From A Virtual Machine?
In the growing world of technologies, Docker and Virtual Machines (VMs) have emerged as go-to solutions for application development and deployment in IT industries. Both VMs and docker containers help you to clone the development environment, which helps you to manage dependencies and configurations better over your primary Operating System. But there are some differences you should be aware of that will help you choose a VM or a Docker container depending on the application.
