- 6. Scheduling & Orchestration Docker Swarm Kubernetes Mesos / Marathon ECS Nomad
- 7. Hypothesis Fast create / destroy + clever schedulers = autoscaling revolution!
- 8. Hypothesis VMs are too slow for on-demand autoscaling
- 9. Hypothesis Microscaling - scale within capacity
- 15. Hypothesis Services with different demand characteristics
- 19. Fantasy or reality? Average utilization: 12%
- 20. Fantasy or reality? Google & Netflix achieve over 50%
