# Docker Engine: from one to hundreds nodes.
## An introduction to the new Docker Engine "Swarm mode".
The recent DockerCon in Seattle has been really amazing.
Among the many announcements made by the Docker team, for sure the most incredible one has been the presentation of the new Docker Engine "Swarm mode" that will be shipped in Docker 1.12.
This feature has really shocked the container orchestration solutions community pushing Docker Swarm from a follower technology to be a potential leader of the competition.
In this talk we will dive into the features of the new Docker Engine "Swarm mode" comparing it to the previous implementation of Docker Swarm.
We will also talk about tools and tips to test the "Swarm Mode" at scale.
