- 9. What and Why of BOSH
- 10. Coordinating a few things is OK
- 11. Coordinating lots of things is hard
- 12. What do we need to be able to do this?
- 13. Bundled releases - identifiabilityWhat do we need to be able to do this?
- 14. Bundled releases - identifiability Integration - reproducibility What do we need to be able to do this?
- 15. Bundled releases - identifiability Integration - reproducibility Deployment framework - consistency What do we need to be able to do this?
- 18. Great for building out servers (but not a software packaging tool) Great for packing up software to deploy anywhere Great for keeping infrastructure in a good state (but designed for servers, not services)
- 19. BOSH can do it all!
- 20. “BOSH is an open source tool for release engineering, deployment, lifecycle management, and monitoring of distributed systems.”

- 33. What and Why Kubernetes
- 35. I have 1000s of containers!!
- 36. What is Kubernetes (K8s) • Kubernetes, is an open-source platform for managing, automating deployment, scaling, and operating containerized applications across a cluster of worker nodes. 36 Capabilities: • Deploy your applications quickly and predictably • Scale your applications on the fly • Seamlessly roll out new features • Optimize use of your hardware by using only the resources you need Role: • K8s sits in the Container as a Service (CaaS) or Container orchestration layer

- 38. What and Why of Kubo
- 42. + = KuBo
- 44. What problem does KuBo solve? Uniform way to instantiate, deploy, and manage highly available Kubernetes clusters. On any cloud.
- 45. What and Why of PKS
- 46. 1)Manifests
- 47. 1)Manifests Open Source Cloud Foundry is about 6000 lines of YAML...
- 48. 1)Manifests Open Source Cloud Foundry is about 6000 lines of YAML... ...and writing YAML is not fun
- 49. 2) Tenancy
- 50. 2) Tenancy Everybody wants their own Kubernetes...
- 51. 2) Tenancy This is difficult.
