- 10. Great but ….. We still haven’t touch on Application patching/upgrading
- 11. Infrastructure as a code
- 12. Company that is using Kubernetes
- 15. Kubernetes official cluster dashboard (which can opt-out)
- 16. Declarative specification on how container should be run
- 17. In Kubernetes, everything is DECLARATIVE https://www.slideshare.net/SatnamSingh67/2015-0605- cluster-management-with-kubernetes
- 18. https://container-solutions.com/kubernetes- deployment-strategies/ Even Deployment(patch/upgrade) strategy are declarative Slow ramped vs Blue-Green
- 19. Persistence Storage and Hyper-converge cluster
