Understanding Basics of Docker Containers

Docker is an open platform for developers and sysadmins to build, ship and run distributed applications. Consisting of Docker Engine, a portable, lightweight runtime and packaging tool and Docker Hub, a cloud service for sharing applications and automating workflows, Docker enables apps to be quickly assembled from components and eliminates the friction among the development, QA and production environments. As a result, IT can ship faster and run the same app, unchanged, on laptops, data center VMs and any cloud.

What can I use Docker for?
 
Faster delivery of your applications

Docker allows your developers to develop on local containers that contain your applications and services. It can then integrate into a continuous integration and deployment workflow. 

Deploying and scaling more easily

Docker’s container-based platform allows for highly portable workloads. Docker containers can run on a developer’s local host, on physical or virtual machines in a data center, or in the Cloud. Docker’s portability and lightweight nature also make dynamically managing workloads easy. You can use Docker to quickly scale up or tear down applications and services. Docker’s speed means that scaling can be near real time.

Achieving higher density and running more workloads

Docker is lightweight and fast. It provides a viable, cost-effective alternative to hypervisor-based virtual machines. This is especially useful in high density environments: for example, building your own Cloud or Platform-as-a-Service. But it is also useful for small and medium deployments where you want to get more out of the resources you have.
