5. No More Servers
6. Big Computer
7. Containers
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/
