9. Cloud Computing

10. Containers + Cloud Computing

11. = Internet Sized Computer

12. How to use an Internet Sized Computer

13. Internet Sized Computers Suck

14. • Big chunks of your computer might disappear for no

    reason • Your data might disappear • Your processes sometimes might not be able to communicate with each other

15. • Some bits of your computer might be on the

    other side of the world • Some people might be man-in-the-middling bits of your computer

16. How to run a process

17. $ echo hello world

18. fork-exec

19. $ docker run ubuntu echo hello world

20. POST /containers/create HTTP/1.1 { "Image": “ubuntu", "Cmd": ["echo", "hello", “world"]

    }

21. $ docker -H anotherhost.oscorp.com \ run ubuntu echo hello world

22. docker client | swarm / \ node1 node2 | |

    docker engine docker engine

23. $ docker -H myswarm.oscorp.com \ run ubuntu echo hello world

24. Docker in the Cloud • IBM Bluemix Containers • Joyent

    SmartDataCenter

25. What can you do with it?

26. Find things that assume computers are slow to start and

    can’t be thrown away

27. $ docker run myapp ./test.sh

28. $ ls tests/**/*_test.py | \ parallel docker run myapp ./test.sh

29. $ ls *.mp4 | parallel “cat {} | docker run

    jrottenberg/ffmpeg ... > out/{}”

30. >>> import dockerrun >>> client = dockerrun.from_env() >>> client.run("ubuntu", "echo

    hello world") 'hello world\n'

31. >>> client.run(“myapp", "tasks/reticulate-splines", wait=False) Infinite task queues

32. How to run an application • Tooling is still in

    its infancy • Look into Compose, Kubernetes, Mesos

33. The future • Networking and storage • Scaling down

34. What if it’s only a second to spin a machine

    up or down? We can start to have machine per web request, or machine per social interaction (IM, tweet or hug). – Timothy Fitz, 2009 http://timothyfitz.com/2009/02/14/cloud-elasticity/
