The results are in - containers are hot hot HOT! Everyone's talking about containers, and you've got a pretty good idea of how they work - but here's your opportunity to take that knowledge to the next level and actually get your hands dirty. In this session we'll cover the basics: when and where to use containers, the benefits and limitations, and even get some hands-on experience with the Docker command line.

Brief History of Containers maybe drop for time

• the problem with software deployments
• a couple of traditional examples
• the answer in Solaris Zones - nobody really noticed
• LXC - Google etc started quietly using them
• virtualization picked up speed

How Do Containers Work

• difference between containers and Docker
• advantages to using Docker
  • Docker Hub / Enterprise / Registry
  • mention Rocket and Joyent also
• how storage works
  • how REX-Ray works
• how networking works

Demo Time

• show Docker CLI
  • show REX-Ray CLI
• spin up a container server in AWS, then bring up [postgresql with storage attached]
  • comparison, bring up [postgresql with storage attached] as a VM, time both
  • have the container checked into a public repo, invite people to do the same on their laptops
