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 2 – creating an AKS cluster using the Azure portal

To create a new AKS cluster with the Azure portal, follow these steps:

  1. Sign in to the Azure portal. Select Create a resource, then Containers | Kubernetes Service.
  2. On the Basics tab, which is shown in the following figure, we will add the following settings:

Figure 10.8 – Create Kubernetes cluster – the Basics tab

To create a Kubernetes cluster, we must set up the following basic information for our AKS cluster:

  • Project details: Select the Azure subscription. We can also create or select a resource group.
  • Cluster details: We can choose a cluster preset configuration to customize the Kubernetes cluster. The options are Standard, Dev/Test, Cost-optimized, Batch processing, and Hardened access. We will select Standard. Fill in the Kubernetes cluster name field and choose a region. In the specified region, our master node will be created. Based on the...
