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 4 – deploying an AKS cluster using an ARM template

An ARM template is a JSON file that defines the different elements related to the infrastructure and configuration for a project.

The template uses a declarative syntax to describe a deployment without writing on a command line to create the deployment of a cluster.

To deploy a new cluster, we can follow this link, which includes a template for creating a new cluster in AKS: https://github.com/Azure/azure-quickstart-templates/tree/master/quickstarts/microsoft.kubernetes/aks.

When we click on Deploy to Azure, we will be redirected to a new page where we can create a new AKS cluster. We can also edit the template or the parameters, or visualize our cluster and the different dependencies:

We will add the different information needed; it is similar to the classic process of creating a new AKS resource. However, we need...
