Since Docker got its start 18 months ago, the Docker Engine has been the core of the project, providing a container approach for application virtualization. The Docker Engine is now being joined by the Docker Machine for increased container deployment portability, Docker Swarm for clustering and Docker Compose for application assembly services.
“We’re moving from a model where an organization runs a few Docker containers on a few hosts to running a large number of containers across many hosts,” Docker CEO Ben Golub explained to eWEEK. “As we move to the model of multi-Docker container distributed applications, it’s necessary to have a rich set of services on the open-source side around orchestration, and there need to be opportunities for Docker Inc. to sell commercial management software.”
One of the new open-source efforts is the Docker Machine service, which, according to Golub, ensures that the host component of the Docker Engine can be easily deployed and run on any server.
