A Developer's Guide to Cloud Apps Using Microsoft Azure

By: Hamida Rebai Trabelsi

Overview of this book

Companies face several challenges during cloud adoption, with developers and architects needing to migrate legacy applications and build cloud-oriented applications using Azure-based technologies in different environments. A Developer’s Guide to Cloud Apps Using Microsoft Azure helps you learn how to migrate old apps to Azure using the Cloud Adoption Framework and presents use cases, as well as build market-ready secure and reliable applications. The book begins by introducing you to the benefits of moving legacy apps to the cloud and modernizing existing ones using a set of new technologies and approaches. You’ll then learn how to use technologies and patterns to build cloud-oriented applications. This app development book takes you on a journey through three major services in Azure, namely Azure Container Registry, Azure Container Instances, and Azure Kubernetes Service, which will help you build and deploy an application based on microservices. Finally, you’ll be able to implement continuous integration and deployment in Azure to fully automate the software delivery process, including the build and release processes. By the end of this book, you’ll be able to perform application migration assessment and planning, select the right Azure services, and create and implement a new cloud-oriented application using Azure containers and orchestrators.

Exercise 1 – creating an AKS cluster using the Azure CLI

In this section, we will create a new AKS cluster using the Azure CLI.

You can open PowerShell and connect to your Azure account using your credentials. If you use the az login command line, you will be redirected to the web interface of Azure to log in to your account. Once you have logged in, you will get JSON output that includes all the information related to your subscription:

You can use the web interface of Azure Cloud Shell by going to https://shell.azure.com/.

Follow these steps to create a new AKS cluster:

  1. Create a new resource group.

We will start by creating a new resource group that will include our AKS cluster with the different resources that will be created with the cluster. We will use the az group create command, as shown:

az group create --name healthcareRG --location eastus
