**Develop, Ship and Run Any Application, Anywhere**
[**Docker**](https://www.docker.io) is a platform for developers and
sysadmins to develop, ship, and run applications. Docker consists of:
sysadmins to develop, ship, and run applications. Docker lets you quickly assemble applications from components and eliminates the friction that can come when shipping code. Docker lets you get your code tested and deployed into production as fast as possible.
Docker consists of:
* The Docker Engine - our lightweight and powerful open source container
virtualization technology combined with a work flow to help you build
and containerize your applications.
* [Docker.io](https://index.docker.io) - our SAAS service that helps you
share and manage your applications stacks.

## Why Docker?
- **Faster delivery of your applications**
* We want to help your environment work better. Docker containers,
and the work flow that comes with them, helps your developers,
sysadmins, QA folks, and release engineers work together to get code
into production and doing something useful. We've created a standard
container format that allows developers to care about their applications
inside containers and sysadmins and operators to care about running the
container. This creates a separation of duties that makes managing and
deploying code much easier and much more streamlined.

deployment of code.
* We make it easy to build new containers, enable rapid iteration of
your applications and increase the visibility of changes. This
your applications, and increase the visibility of changes. This
helps everyone in your organization understand how an application works
and how it is built.
* Docker containers are lightweight and fast! Containers have
sub-second launch times! With containers you can reduce the cycle
time in development, testing and deployment.
sub-second launch times, reducing the cycle
time of development, testing, and deployment.
- **Deploy and scale more easily**
* Docker containers run (almost!) everywhere. You can deploy your
containers on desktops, physical servers, virtual machines, into
data centers and to public and private clouds.
* As Docker runs on so many platforms it makes it easy to move your
data centers, and up to public and private clouds.
* Since Docker runs on so many platforms, it's easy to move your
appications around. You can easily move an application from a
testing environment into the cloud and back whenever you need.
* The lightweight containers Docker creates also making scaling and
down really fast and easy. If you need more containers you can
quickly launch them and then shut them down when you don't need them
anymore.
* Docker's lightweight containers Docker also make scaling up and
down fast and easy. You can quickly launch more containers when needed and then shut them down easily when they're no longer needed.
- **Get higher density and run more workloads**
* Docker containers don't need a hypervisor so you can pack more of

licenses.
- **Faster deployment makes for easier management**
* As Docker speeds up your work flow it makes it easier to make lots
of little changes instead of huge, big bang updates. Smaller
changes mean smaller risks and mean more uptime!
