with Jérôme Petazzoni, Tinkerer Extraordinaire, Docker
Linux containers are different from Solaris Zones or BSD Jails: they use discrete kernel features like cgroups, namespaces, SELinux, and more. We will describe those mechanisms in depth, as well as demo how to put them together to produce a container. We will also highlight how different container runtimes compare to each other.

Docker is an open platform for developers and system administrators to build, ship and run distributed applications. With Docker, IT organizations shrink application delivery from months to minutes, frictionlessly move workloads between data centers and the cloud and can achieve up to 20X greater efficiency in their use of computing resources. Inspired by an active community and by transparent, open source innovation, Docker containers have been downloaded more than 700 million times and Docker is used by millions of developers across thousands of the world’s most innovative organizations, including eBay, Baidu, the BBC, Goldman Sachs, Groupon, ING, Yelp, and Spotify. Docker’s rapid adoption has catalyzed an active ecosystem, resulting in more than 180,000 “Dockerized” applications, over 40 Docker-related startups and integration partnerships with AWS, Cloud Foundry, Google, IBM, Microsoft, OpenStack, Rackspace, Red Hat and VMware.

The moment slides are replaced by the speaker, the line of thought/understanding is lost. The slides must be visible all the time. Great talk but bad camera placement.

Yes. One example is Kata. It’s uses virtualisation to run containers. It’s open source.

I don't mean to be disrespectful but this was 45 minutes of lame ass slides and jokes followed by 8 minutes of pure gold. I would have loved to have 53 minutes of that powerful demonstration. If anyone reads this and knows a place where this man demonstrates slowly and explains how to create the illusion of a container using Linux commands and all the other cgroup layers then please reply to this comment. Very impressive.

in my mind - yes. cgroups are still cgroups, namespaces are namespaces, copy-on-write is copy-on-write. Can't see anything major changing there? Could be wrong, if so I hope someone corrects me, but I think the main innovation since this video went into container orchestration and everything that came out of that

Not sure who really needs to know this stuff. If you're planning on creating the next Docker Corp maybe it's useful. If you merely want to use Docker.... I imagine pretty much none of this stuff is needed.
