Azure Kubernetes Service (AKS) cluster architecture and operations

Overview

Module 1: Learn how to choose between Azure CNI and kubenet, two networking plugin options for an Azure Kubernetes Service cluster.
By the end of this module, you'll be able to:
- "Understand what a Kubernetes network plugin is"
- "Understand the pros, cons, and limitations of kubenet"
- "Know how to deploy an AKS cluster with kubenet"
- "Understand the pros, cons, and limitations of Azure CNI"
- "Know how to deploy an AKS cluster with Azure CNI"
Module 2: In this module, we take a detailed look at the process of designing an Azure Kubernetes Service network using the Azure Container Network Interface (CNI) plug-in.
By the end of this module, you're able to:
- List the key Kubernetes resource types that require network access.
- Assess an application's needs and how that could affect network design.
- Understand the steps to size an Azure Kubernetes Service cluster for a workload.
- Design a network for an Azure Kubernetes Service cluster using Azure CNI
Module 3: Apply the latest version upgrades and patches to your Azure Kubernetes Service clusters.
By the end of this module, you'll be able to:
- Understand what Kubernetes versions are supported by Azure Kubernetes Services (AKS).
- Upgrade your existing Azure Kubernetes Services (AKS) clusters components to the latest supported Kubernetes version.
- Understand how to adopt a Blue/Green deployment to upgrade your Azure Kubernetes Services clusters in a production environment.
Module 4: In this module, we'll discuss how to use Azure Policy for Kubernetes to enforce rules and detect non-compliance in AKS clusters.
By the end of this module, you'll be able to:
- Deploy the Azure Policy and Azure Monitor add-on for Azure Kubernetes Service
- Use Azure Policy to enforce rules and manage compliance state of your Azure Kubernetes Service cluster
- Monitor cluster compliance status using Azure Policy
- Run queries to see runtime operation of policies in AKS clusters
