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.

Summary

In this chapter, we learned about the development process for Docker-based applications, and the fundamentals and terminologies of Docker and ACR. We learned about ACI and discussed how it differs from ACR. We understood the container design principles and how we can manage states and data in Docker applications. We also built and managed containers with tasks.

We learned that a Dockerfile is a text file that includes the different instructions presented as a command to build images automatically, and we explored the different elements of a Dockerfile for use after deployment. Finally, we deployed Docker containers using different environments, first with an Azure VM on Windows and Linux and second on ACR.

If you have multiple containers, is it easy to manage them? Do we need another tool to orchestrate them? This is the topic of the next chapter. We will learn about container orchestration when building microservices and multi-container applications, ensuring that we...
