3. WHAT IS HEROKU
4. WHAT IS HEROKU a Platform as a Service
5. WHAT IS HEROKU a Platform as a Service developer productivity
7. 4000 heroku apps
8. 4000 heroku apps 500+ releases a day
9. 4000 heroku apps 500+ releases a day 200+ deploys a day
10. 4000 heroku apps 500+ releases a day 200+ deploys a day 105 public github repos
11. 4000 heroku apps 500+ releases a day 200+ deploys a day 105 public github repos 85 people

14. WHAT IS HEROKU a Platform as a Service developer productivity a cloud unix
15. UNIX
16. UNIX small sharp tools

20. Heroku as UNIX for developers
21. Do 1 thing do it well Heroku as UNIX for developers
22. Do 1 thing do it well Straightforward Setup Heroku as UNIX for developers
23. Do 1 thing do it well Straightforward Setup Lower barrier to entry Heroku as UNIX for developers
24. Do 1 thing do it well Straightforward Setup Lower barrier to entry
25. Small functional apps Do 1 thing do it well Straightforward Setup Lower barrier to entry
26. Small functional apps An example (KISSMetrics Data Loader): Do 1 thing do it well Straightforward Setup Lower barrier to entry
27. Small functional apps An example (KISSMetrics Data Loader): Open DB connection Do 1 thing do it well Straightforward Setup Lower barrier to entry
28. Small functional apps An example (KISSMetrics Data Loader): Open DB connection Run query Do 1 thing do it well Straightforward Setup Lower barrier to entry
29. Small functional apps An example (KISSMetrics Data Loader): Open DB connection Run query Post data Do 1 thing do it well Straightforward Setup Lower barrier to entry
30. Small functional apps An example (KISSMetrics Data Loader): Open DB connection Run query Post data Others: OAuth, Vault, API, Core, Canary, Add-ons, Success, etc. Do 1 thing do it well Straightforward Setup Lower barrier to entry
32. Run and forget
33. Run and forget Alert me when things break
34. Do 1 thing do it well Straightforward Setup Lower barrier to entry
35. git clone git://github.com/heroku/... heroku create -s cedar git push heroku master Do 1 thing do it well Straightforward Setup Lower barrier to entry
36. Heroku as UNIX for developers Do 1 thing do it well Straightforward Setup Lower barrier to entry
37. 4000 heroku apps 500+ releases a day 200+ deploys a day
38. Release Early Release Often
39. Defined Contract/API Release Early Release Often
40. Defined Contract/API Developer environments Release Early Release Often
41. Defined Contract/API Developer environments Environment parity Release Early Release Often
42. Defined Contract/API Developer environments Environment parity
43. Defined Contract/API Developer environments Environment parity
44. heroku create -s cedar mystaging-app git remote add staging git@github.com:heroku/... git push staging master git push production master Defined Contract/API Developer environments Environment parity
45. production = staging = dev minimized divergence enables continuous deployment Defined Contract/API Developer environments Environment parity
46. settings/ local_settings.py dev_settings.py staging_settings.py production_settings.py Defined Contract/API Developer environments Environment parity
47. settings/ local_settings.py dev_settings.py staging_settings.py production_settings.py Defined Contract/API Developer environments Environment parity
48. settings.py DATABASE = os.environ[‘DATABASE_URL’] Defined Contract/API Developer environments Environment parity SENTRY_DSN = os.environ[‘SENTRY_DSN’] REDIS = os.environ[‘REDIS_URL’]
49. 4000 heroku apps 500+ releases a day 200+ deploys a day 105 public github repos
50. More than a codebase
51. 4000 heroku apps 500+ releases a day 200+ deploys a day 105 public github repos 85 people 21 teams
52. 21 teams Web Apps - 2 people Runtime - 3 people API - 3 people Routing - 3 people Security - 3 People Developer Experience - 5 people Data - 9 people
53. 21 teams - almost as many tools

65. ownership productivity agility Team Design
66. ownership productivity agility You choose the tools to get the job done, you support the API for others, you own the features to make users happier, you ensure it works, you carry the pager
67. ownership productivity agility Broad focus around quality, quality comes from solid engineering, give time to engineers, less meetings more get shit done
68. ownership productivity agility Iterate fast and often, a failed attempt is a successful experiment, culture around seeing/doing over talking
69. ownership productivity agility “When can I see it”
70. ownership productivity agility Iterate fast and often, a failed attempt is a successful experiment, culture around seeing/doing over talking
71. Teams don’t communicate the same way
72. More than a codebase
73. Github issues is
74. Github issues is centralized
75. Github issues is centralized, is asynchronous,
76. Github issues is centralized, is asynchronous, hands off ownership
77. Github issues alone doesn’t fix communication Engineering culture of building and sharing
78. Github issues alone doesn’t fix communication Engineering culture of building and sharing
79. 4000 heroku apps 500+ releases a day 200+ deploys a day 105 public github repos 85 people 21 teams
80. Quality
81. Quality Quality Quality Hire for Quality
82. Quality Quality Quality Hire for Quality & Culture
83. Let them Work Quality Quality Quality
84. Quality doesn’t work with deadlines Quality Quality Quality
85. Quality
86. Quality Small teams: Ownership Productivity Agility
87. Release early, release often: Defined Contract/API Developer environments Environment parity Quality Small teams: Ownership Productivity Agility
88. Apps that: Do 1 thing do it well Straightforward Setup Lower barrier to entry Release early, release often: Defined Contract/API Developer environments Environment parity Quality Small teams: Ownership Productivity Agility
