A Developer's Guide to Building Resilient Cloud Applications with Azure

By: Hamida Rebai Trabelsi

Overview of this book

To deliver software at a faster rate and reduced costs, companies with stable legacy systems and growing data volumes are trying to modernize their applications and accelerate innovation, but this is no easy matter. A Developer’s Guide to Building Resilient Cloud Applications with Azure helps you overcome these application modernization challenges to build secure and reliable cloud-based applications on Azure and connect them to databases with the help of easy-to-follow examples. The book begins with a basic definition of serverless and event-driven architecture and Database-as-a-Service, before moving on to an exploration of the different services in Azure, namely Azure API Management using the gateway pattern, event-driven architecture, Event Grid, Azure Event Hubs, Azure message queues, FaaS using Azure Functions, and the database-oriented cloud. Throughout the chapters, you’ll learn about creating, importing, and managing APIs and Service Fabric in Azure, and discover how to ensure continuous integration and deployment in Azure to fully automate the software delivery process, that is, the build and release process. By the end of this book, you’ll be able to build and deploy cloud-oriented applications using APIs, serverless, Service Fabric, Azure Functions, and Event Grid technologies.

Exploring the Cosmos DB SQL API

Azure Cosmos DB supports multiple APIs models, which makes it possible for you to select the ideal API for your application. In this section, we will specifically drill down into this SQL API. The Cosmos DB SQL API is the default Azure Cosmos DB API. You can store data using JSON documents to represent your data. Even though we are using the SQL API, we will still get to take advantage of all of the core features of Cosmos DB that are universal across all APIs.

The Core API for Cosmos DB is recommended when you’re building new solutions. This API uses SQL as a query language, along with JavaScript as its programming language. Both of these languages are pretty universal and popular, making it more likely that you already have experience with both.

Talking about the SQL query language specifically, you can write queries against Cosmos DB using the same SQL syntax you would use with products such as Microsoft SQL Server. Even though you are...
