Docker (source code for core Docker project) is an infrastructure management platform for running and deploying software. The Docker platform is evolving so an exact definition is currently a moving target, but the core idea behind Docker is that operating system-level containers are used as an abstraction layer on top of regular servers for deployment and application operations.
Docker can package up applications along with their necessary operating system dependencies for easier deployment across environments. In the long run it has the potential to be the abstraction layer that easily manages containers running on top of any type of server, regardless of whether that server is on Amazon Web Services, Google Compute Engine, Linode, Rackspace or elsewhere.
