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.

Monolithic versus microservices

In this section, we will discuss the difference between monolithic architecture and microservices architecture.

Before talking about microservices and their different benefits, we need to understand the difference between monolithic architecture and microservices architecture.

Monolithic architecture

There are two dominant styles of software architecture among software developers and architects today. In monolith architecture, components are coupled to each other and distributed as a single package. But with this architecture, we have several advantages to consider. Development is really simple because all the code is in one place, so it’s easy to find things. The deployment is also simple because when you come to deploy it to production, well, there’s just one application to update, and the communication between the components takes place in the same process. It is, therefore, very easy to plan communication between components...
