- 4. Gotta Have It! PROS Increase velocity of change/responsiveness Get Operations out of the loop Buzzword compliance – aka Shiny!!!
- 5. PROS Increase velocity of change/responsiveness
- 6. PROS – Ops Gets Out of Loop Less work for Operations Developers feel more in control
- 7. Gotta Have It! CONS Increase velocity of change Shared responsibility Not always easy

- 18. Rake
- 19. Packaging But it's sooooo hard save yourself first.....
- 21. Building a Gem
- 22. Right Tool Packages Something that does not change often Don't need to roll back quickly Don't need more than 1 version at a time You cache external repos or limit to just yours
- 23. Right Tool Gems Fast roll back – gem cache Easy setup of gem server Need more than 1 version at a time Bundler for dependencies Bundle exec for peace of mind
- 24. Configuration Management Puppet everything from bare metal/base image Seperate data from manifests with an ENC Max troubleshooting time is 20 minutes Amazon free ”chaos monkey” service
- 25. Puppet – Start with a sane base
- 26. ENC – Use Groups! http://docs.puppetlabs.com/guides/installing_dashboard.html
- 27. ENC – Node Entries Inherit
- 28. ENC – Scripting Additions
- 29. ENC - Output
- 30. Manifests Contain ENC Variables
- 31. Templates Contain ENC Variables
- 32. Puppet - Tips Execs hurt – try to avoid them Recursive directories – use vcsrepo instead Write your own types – just restart in between Run mongrel or passenger Use behind a load balancer for fun Use reporting, but take the DB off of your master Write your own facts and save lots of time
- 33. Puppet - Scaling
- 34. Mcollective – Do It NOW!! Orchestration framework Crazy Parallel Write more ruby code... Clients and Agents
- 35. Mcollective – Crazy Parallel 6380 nrpe checks across 370 hosts in 3.8 seconds
- 36. Use Facts and Classes to Filter
- 37. Mcollective – Custom Agent
- 38. Mcollective – Custom Client
- 39. Mcollective - Tips Remeber you have a machine gun pointed at your foot Wrap command in IO.popen and log everything Log to syslog Use ApacheMQ For EC2 tune your keep alives (registerinterval) Remember you have a machine gun pointed at your foot
- 41. Sinatra Web app in 5 minutes Much more minimal than rails Written in Ruby so I can interface with Mcollective easily http://www.sinatrarb.com/
- 42. Sinatra – Addons sinatra-respond_to - useful as API Pony – send email from Sinatra Twitter Bootstrap – make things pretty
- 44. Public Example
- 45. Really Simple
- 46. Sinatra - Tips Run a few behind Nginx Use helpers whenever possible Log every push Use it to integrate all your data
- 48. Dashboard Functionality Push software Audit software Real-time monitoring check Performance data integration Log data integration Troubleshooting tools for developers Utilities for non-technical staff Open trouble tickets Cost information (in progress) Userful links to other data sources
