Slides given at Agile 2015 to support talk with Josh Long Walks through basic ideas of Cloud Foundry BOSH, Cloud Foundry Elastic Runtime and Spring Boot/Spring Cloud. Covered these slides in ~20 minutes, then did 50 minutes of Lattice demos and Spring live coding.

1. open source, patterns,
cloud native architecture

2. continuously deploying
microservices

3. the devops contract

5. that devops guy Java champion

6. changing the way the world builds software

7. Principles > Practices > Tools

8. cloud

9. There is something
happening here.

10. distributed systems deploying
distributed systems deploying
distributed systems

11. distributed systems operating
distributed systems operating
distributed systems

13. conclusion:
continuous delivery - why
microservices - what
devops - how

14. going faster and safer

15. continuously delivered
microservices are the natural
evolution for services that
need to operated at scale and
also be changed frequently

16. also, despite what you might
have heard, if you want to move
fast at scale, architecture matters

17. you must be this tall
• rapid provisioning
• basic monitoring
• rapid deployment
• devops culture

18. everything we share
today is open source

19. byoc:
bring your own culture

20. Operations
The ‘Not So Secret Any More’ Sauce

21. cloud native operations:
• api driven
• service centric
• change enabling

22. Learn BOSH
http://mariash.github.io/learn-bosh/
• Identifiability
• Reproducibility
• Consistency
• Agility

23. Why BOSH?
• multi-cloud
• clean separation of systems
• consistent rapid provisioning
• scale up/scale down
• built in health monitoring
• fault remediation
• canary deployments

24. BOSH Contract
•current_vm_id
•create_stemcell
•delete_stemcell
•create_vm
•delete_vm
•has_vm?
•reboot_vm
•set_vm_metadata
•configure_networks
•create_disk
•delete_disk
•attach_disk
•snapshot_disk
•delete_snapshot
•detach_disk
•get_disks

25. CLI
Director
message
bus
worker
VMs
IaaS
object storage
health
monitor

26. Learning BOSH

27. lots of other tools
you don’t have to use mine
understanding BOSH can will make whatever you do better

28. cloud native runtimes:
• distributed scheduling
• process/containers
• integrated pipelines
• fault remediation
• the new middleware

29. routers
Linux
LinuxLinux
Containers
message
bus
cloud controller
loggregators
controller
DB
etcd
hm9000
metrics firehose
a couple dozen services
UAA
login
What even is Elastic Runtime?
service
brokers
object
store
stagers

30. looks suspiciously like
Platform as a Service

31. •role based access
•on demand deploy
•coordinate across services
•routing requests
•read, write data
•add/remove resources
•emit and record events
•isolate resources/failures
•measure performance/health
•detect failures
•remediate failures
•work on day 2
Platform Contract/Capabilities

32. ad hoc automation is a problem
masquerading as a solution

33. A platform makes promises.
A contract allows the platform to
keep promises.

35. lots of other tools
you don’t have to use mine
understand Cloud Foundry Elastic Runtime

36. cloud native application:
• 12 factor contract
• composable
• discoverable
• fault tolerant

37. •I. Codebase
•II. Dependencies
•III. Config
•IV. Backing Services
•Build, release, run
•VI. Processes
•VII. Port binding
•VIII. Concurrency
•IX. Disposability
•X. Dev/prod parity
•XI. Logs
•XII. Admin processes

38. ‘boot’ makes microservices easy
‘cloud’ provides composable patterns

39. • configuration service
• service registry
• service discovery
• load balancing
• circuit breaker
• micro-proxy
• api gateways

40. If you are one of those people who like to read books…

41. lots of other tools
you don’t have to use mine
understand Spring Cloud/Spring Boot/NetflixOSS

42. Runtimes
Infrastructures
Applications
contract
contract
Cultures
Cloud Native

43. ask me about
cloud native
continuous integration

45. lots of other tools
you don’t have to use mine
but concourse.ci will blow your mind

46. Principles > Practices > Tools

48. changing the way the world builds software
We are uncovering better
ways of developing
software by doing it and
helping others do it.
