12 Factor App in 12 Minutes
Your cloud app report card
Matt Momont, Software Developer

Why 12 Factors
• Strange things happen in the “The Cloud”
– Think: Network explosions, data center
explosions, server explosions
• The cloud requires a new way of developing
apps
• These 12 factors will help you build your next
cloud app safely.
12factor.net
28. GE Digital
1. Codebase
Level I. Email src zip with different name
Level II. Frequent commits to source control
App lives in one repo
Level III. App is broken into system
Each piece is an app in its
own repo
29. GE Digital
2. Dependencies
I. Manually download jars to /lib
II. Use package manager (mvn, npm)
Expect tools to be provided (curl)
III. Use artifact manager (Artifactory)
Bundle dependencies and tools
New
30. GE Digital
3. Config
I. Hardcode URLs, passwords in code
Use code like: if(Mode.PROD)
II. Use config files
Multiple config files for different
environments
III. Use config service (Spring Cloud Config,
Zookeeper)
31. GE Digital
4. Backing Services
I. Vendor specific connection libraries
Hardcode connection strings
II. Connection parameters live in config files
III. Resources are found dynamically
Update backing services independently
32. GE Digital
5. Build, Release, Run
I. Devs build and deploy code from local
Production is pushed manually
II. Use build/release tools (Jenkins, Travis CI)
Cleanly separate build and deploy steps
III. Have one click release pipeline
Each release is versioned and saved for
rollback
No human intervention
33. GE Digital
6. Processes
I. Sticky session
Write app data to local filesystem
II. Does not rely on data stored locally
III. Stateless
Store session data in datastore (redis)
Cache intermediate transaction steps
34. GE Digital
7. Port Binding
I. Deploy to app container
II. Standalone, but listens to specific ports
III. Web server is part of app (node, netty)
App exports HTTP as a service
35. GE Digital
8. Concurrency
I. Blocking tasks that must run sequentially
II. Non-blocking IO server (node, netty)
III. Scale horizontally
Small, independent microservices
Scale out, not up.
36. GE Digital
9. Disposability
I. Needs a dev to coordinate reboot
II. Fast startups
III. Crashes gracefully
Sub 1 second restarts
Stores state to quickly recover
Your servers are cattle,
not pets.

37. GE Digital
10. Dev/Prod Parity
I. Devs have no insight to prod
Dev is different from prod
II. Substitute lightweight replacements
(In-memory H2, SQLite)
III. Environments are identical
SQLite ≠ Postgres
38. GE Digital
11. Logs
I. System.out.print()
II. Write to log files on web server
III. Treat logs like a stream (ELK)
39. GE Digital
12. Admin Processes
I. Edit database entries manually
II. Store migration scripts in repo
III. Use framework’s tooling

AMQP, MQTT
• RabbitMQ is available as a service on most CF
based hosted PaaS
• RabbitMQ supports:
– AMQP
– MQTT Adapter available

Summary
• Devices/Machines talk different protocols
• Two ways to connect machines to Cloud
Foundry
– Cloud Foundry services
– TCP router
68. GE Digital
Predix.io: You’ve got the power
• You get your own authorization server(s)
– Manage identities (SCIM)
– Manage OAuth clients
– Federate with external IdPs
• Configure any service from the marketplace
as an OAuth resource server
• Configure any app you deploy as an OAuth
client
69. GE Digital
OAuth Limitations
• Dynamic & fine-grained access control
– Access Control Service
• Revocation
– RFC 7009
• Impersonation (i.e. act-as, on-behalf-of)
– ???
