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.

Understanding Azure hosting options

In this section, we will present the Azure hosting options that we need to consider before migrating to the cloud.

The lift and shift model is based on the principle of moving your existing applications or services to Azure VMs, with operating systems and network configurations similar to their current on-premises configuration when deploying in a cloud platform. A successful lift and shift migration leverages the benefits of cloud infrastructure and manageability, while minimizing both migration costs and the time required to complete the migration.

The following figure presents the different options to consider before migrating an application:

When migrating .NET applications, or even new applications, to Microsoft Azure, consideration must be given to the choice of compute, database, networking and security, governance, and authentication...
