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 Container Registry

ACR is an Azure service that is used for creating private Docker registries.

It is similar to Docker Hub but offers a few unique benefits: ACR runs in Azure, is highly scalable, and provides enhanced throughput for Docker pulls that can span many nodes concurrently.

ACR facilitates version control for container images. Developers push container images to container registries, and administrators pull those images from registries. A container registry provides image versioning and helps you to manage tagged versions. ACR is a fundamental building block that enables the distribution of container images. Instead of uploading container images directly from your development environment to your server, continuous deployment tools are often instrumented to pull images from container registries and put them on servers. ACR has many features for security and high availability. First, access to container registries can be controlled using Azure Active...
