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.

Exploring Azure Kubernetes Service and Azure Container Apps

Azure offers orchestration services to manage multiple containers. In the preceding chapter, Chapter 8, Building a Containerized App Using Docker and Azure Container Registry, we explored the use of Azure Container Registry to store and manage private container images. If we use a single container, we don’t need any orchestration solution – we can simply use Azure Container Instances or Azure App Service as a container to run isolated containers. For multiple containers, we can use Azure Kubernetes Service and Azure Container Apps. In the following figure, we will present the different Azure services for containers:

A Kubernetes cluster is a set of Docker hosts; the cluster deploys these hosts in a single virtual Docker host. A Kubernetes cluster allows you to deploy multiple containers in the cluster. This Deployment scales...
