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.

Evaluating migration considerations

Understand your application environment so that you can select an application that will have the most impact and benefit and be an ideal candidate for the migration of other applications. Assess your entire application portfolio and migrate only the selected candidate first.

Data security and confidentiality are essential elements; it is very important to ensure compliance with internal policies and legal or regulatory requirements. In the analysis and planning phase, a key step is to know the different types of data used in the service to be migrated, in order to establish a data encryption model and the isolation of user accounts from each other by ensuring well-controlled cross-account access. Risk management leads to decision-making on appropriate security measures for each type of data and also an assurance of data compliance.

In order to avoid surprises and overcome all the challenges when migrating applications and their data, take your...
