Azure Kubernetes Service (AKS) is a managed container orchestration service. With Kubernetes continuing to grow in popularity, many developers and IT engineers are curious to get started. Roy will demonstrate hosted microservices applications and the Istio service mesh. Along with how to manage your cluster with the Kubernetes Dashboard, Prometheus, Grafana and Azure Monitor. You will see a practical overview how all these pieces fit together. www.roykim.ca Twitter: @RoyKimYYZ Github: https://github.com/RoyKimYYZ

4. Presentation Objectives
By: Roy Kim roykim.ca
 See many applications run in one AKS cluster
 How to manage the applications with various tools
 Come away with a better understanding how apps,
Kubernetes objects and Azure resources work together.

5. What is Azure Kubernetes Service?
By: roy@roykim.ca
 A managed container orchestration service
 Service discovery
 Load balancing, availability
 Auto-scale
 Pod/container deployment and resource allocation
 Health monitoring and more
 Supports microservices based applications
 Focus on the application workloads, not the underlying infrastructure.
 Provides a declarative approach to deployments, backed by a robust set of
APIs for management operations.
 Build your applications with your preferred programming language, OS,
libraries, or messaging bus.
