Instead of talking about what apps we run on a given host operating system, we now ask what containers we run on the cluster.

14. In other words, the cluster (not the host) is now the primary object.

15. For developers, this means…
All the freedoms of running in containers (I own the entire FS)
Parity between dev and prod is increased
“Hard problems” like dependency management are now easy
But my dev environment is now more complex
The conceptual overhead for understanding ops is higher
And persistence is hard

16. Our Challenge
How do we increase the effectiveness of a developer in the container-first world of tools like Docker and Kubernetes?

17. Demos: Tools for Container-first Development

18. Let’s start by just running a single container in Azure.

19. Azure Container Instances
Run individual containers inside of Azure. It’s serverless, but not Function-as-a-Service.

20. Demo: ACI
Running a Tiny JS App

21. Now let’s use Kubernetes

22. Azure Container Services
Get yourself a powerful preconfigured Kubernetes cluster running inside of Azure.

28. Kubernetes Helm
Helm is the package manager for Kubernetes. It simplifies the process of installing and managing applications on a Kubernetes cluster.

33. Demo: Kube-Lego

34. Using ACI with Kubernetes
There is a Kubernetes bridge to ACI that lets us run Kubernetes pods as ACI resources.
This means (a) we don’t consume node resources, and (b) these resources can be billed per second.
