Overview

This is a step by step practical guide for implementing end-to-end microservice docker based architecture using Kubernetes on top of Azure Kubernetes Service [AKS]. The practical guide will takes you through the steps of creating a Kubernetes cluster, deploying a SQL server database & microservices-based application, load balancing and securing inbound traffic, scaling option in AKS and how can you monitor your cluster in production environment.

At the end of this practical guide you will understand AKS inside out, and will be able to design and implement production ready Kubernetes clusters.

The K8s cluster will be hosted on AKS and integrated with azure container register for hosting the container images. AKS RBAC and Azure Active directory will be used to authenticate and authorize access to the AKS cluster and Azure monitor will be used to monitor the cluster.

We are using https://icodeforu.com website for hosting on this cluster

Target Audience

• Developers and architects looking to learn azure kubernetes services
• Beginners who would like to explore the world of cloud native concepts
• Beginners looking to learn administrating kubernetes clusters

Prerequisites

We assume anyone who wants to understand Kubernetes should have an

• Understating of how the Docker works,
• How the Docker images are created, and how they work as a standalone unit.
• To reach to an advanced configuration in Kubernetes one should understand basic networking and how the protocol communication works.
• Familiar with cloud computing and IT concepts
• Familiar with containers is an advantage
