Slides from my presentation at Azure Saturday on 26.5.2018 in Munich. There’s a plethora of Container-related services available in Azure: Azure Container Instance, Azure Container Service, managed Kubernetes and managed container registry to name a few. It can be hard to get your head around all of them, especially if you come from Microsoft background as I did. I will cover the most useful container and container orchestration related services in this talk, explain their differences and help you figure out which scenarios they fit best.

5. AGENDA
• Container & Orchestration 101
• Containers in Azure
• Tooling
• Roadmap

7. HISTORY
• Brendan Burns joined Microsoft in 2016
• Gabe Monroy joined Microsoft in 2017 (Deis acquisition)
• Major focus on supporting open source in the cloud

8. WHAT IS A CONTAINER?
Containers = operating system virtualization
OS
Kernel
Applications
Container Container Container
Hardware
Virtual machines = hardware virtualization
Hardware
OS
Application
VM VM VM

9. WHY CONTAINERS?
• Fast
o VM startup usually takes a few minutes
o Containers start in seconds
• Small
o Union filesystem makes individual container images small
o Small containers mean high hardware utilization
• Immutable and portable
o Dependencies are guaranteed to be present wherever the container runs
o No more “works on my machine” fights between dev and ops

10. CONTAINER ORCHESTRATION
• Creating a single container or even composing an application with 4 or 5
containers is easy
• When you get to production, your container workloads can have 10’s or
hundreds of container images, scaling to thousands of running containers
• Orchestrator takes your containers and deploys them within a cluster of
virtual machines, then monitor their health as they run, load balancing
them as required.
• Historically orchestrators have been a pretty big pain to set up

11. CONTAINER ORCHESTRATOR FEATURES

12. Embrace containers
as ubiquitous
Support containers
across the compute
portfolio
Democratize
container technology

14. CONTAINERS IN AZURE
• Azure Container Instance
o Create a container from an Azure image without worrying about virtual machines underneath
• Azure Container Registry
o Store your Docker images in a private registry as a service
• Azure Container Service
o Create DC/OS, Swarm or Kubernetes cluster in Azure

15. AZURE CONTAINER INSTANCES (ACI)
$ az container create --resource-group myResourceGroup --name
mycontainer --image microsoft/aci-helloworld --cpu 1 --memory 1 --ip-
address public --ports 80
"ipAddress": {
"ip": "52.168.86.133",
"ports": [...]
},
"location": "westeurope",
"name": "mycontainer",
