Back in 2015, as part of a DevOps presenation, I put together a slide showing the container landscape. For fun I've created an updated version showing the environment today. This slide set incluces both landscapes along with the orginal talk track that went with the 2015 landscape.

Slide 2 of 22
• Internal Use - Confidential
At this point [December 2015] the container landscape is an ever-changing field populated by small and
large players. This space is dominated by open source offerings.
Container engines: As the center of gravity for environment are the container engines themselves made
up by the 800-pound gorilla, Docker as well as Rocket which was created by CoreOS in response to what
CoreOS felt was a lack of security in the Docker container. This summer the Open Container Initiative
was kicked off to bring the two sides together and create a common spec.
MicroOS’s: Sitting beneath the containers are the micro OS’s, basically the size of 25 pictures on your
cell phone (100 MB) or 1/20th the size of a typical OS. What makes these so small is that they have
been stripped down to the bare necessities eg no fax software included. These began with CoreOS and
now there are offerings from Red Hat (atomic), Microsoft (nano), VMware (photon) and Rancher etc
(others include Intel’s ClearOS and Ubuntu’s Snappy)
Container Orchestration: Just like having VM or server sprawl, you have container sprawl and need to
be able to manage them. The offering that sits at the center is Google’s Kubernetes built on their own
container management platform and which can combined with the other orchestration offerings. The
others include, Rancher, Docker Swarm, CoreOS, Mesosphere (based off of the Apache Mesos project)
and Flocker a container data volume manager
Clouds with Docker Support: Most clouds are now building docker support from OpenStack to Joyent’s
trident, Google’s container engine, ECE and Microsoft Azure

At the same time the center of gravity shifted relatively quickly from Docker to Kubernetes
