Docker is the world’s famous software container platform. Developers use Docker to eliminate “works on my machine” problems when collaborating on code with co-workers. Operators use Docker to run and manage apps side-by-side in isolated containers to get better compute density. Enterprises use Docker to build agile software delivery pipelines to ship new features faster, more securely and with confidence for both Linux and Windows Server apps.
What is a Container?
Using containers, everything required to make a piece of software run is packaged into isolated containers. Unlike VMs, containers do not bundle a full operating system - only libraries and settings required to make the software work are needed. This makes for efficient, lightweight, self-contained systems and guarantees that software will always run the same, regardless of where it’s deployed.

Docker For Developers
Docker automates the repetitive tasks of setting up and configuring development environments so that developers can focus on what matters: building great software. Developers using Docker don’t have to install and configure complex databases nor worry about switching between incompatible language toolchain versions. When an app is dockerized, that complexity is pushed into containers that are easily built, shared and run. Onboarding a co-worker to a new codebase no longer means hours spent installing software and explaining setup procedures. Code that ships with Dockerfiles is simpler to work on: Dependencies are pulled as neatly packaged Docker images and anyone with Docker and an editor installed can build and debug the app in minutes.
Docker for Ops
Docker streamlines software delivery. Develop and deploy bug fixes and new features without roadblocks. Scale applications in real time. Docker is the secret weapon of developers and IT ops teams everywhere, allowing them to build, ship, test, and deploy apps automatically, securely, and portably with no surprises. No more wikis, READMEs, long runbook documents and post-it notes with stale information. Teams using Docker know that their images work the same in development, staging, and production. New features and fixes get to customers quickly without hassle, surprises, or downtime.
For the Enterprise
Docker is at the heart of the modern app platform, bridging developer and IT, Linux and Windows. Docker works in the cloud just as well as on-premise; and supports both traditional and microservices architectures. Use Docker to build, network, secure and schedule containers and manage them from development to production. Docker sets enterprises on the path to digital transformation by enabling all apps to be agile, cloud-ready and secure at optimal costs.
