Learning Azure Cosmos DB

By: Shahid Shaikh

Overview of this book

<p>Microsoft has introduced a new globally distributed database, called Azure Cosmos DB. It is a superset of Microsoft's existing NoSQL Document DB service. Azure Cosmos DB enables you to scale throughput and storage elastically and independently across any number of Azure's geographic regions.</p> <p>This book is a must-have for anyone who wants to get introduced to the world of Cosmos DB. This book will focus on building globally-distributed applications without the hassle of complex, multiple datacenter configurations. This book will shed light on how Cosmos DB offers multimodal NoSQL database capabilities in the cloud at a scale that is one product with different database engines, such as key-value, document, graph, and wide column store. We will cover detailed practical examples on how to create a CRUD application using Cosmos DB with a frontend framework of your choice. This book will empower developers to choose their favorite database engines to perform integration, along with other systems that utilize the most popular languages, such as Node.js. This book will take you through the tips and trick, of Cosmos DB deployment, management, and the security offered by Azure Cosmos DB in order to detect, prevent, and respond to database breaches.</p> <p>By the end of this book, you will not only be aware of the best capabilities of relational and non-relational databases, but you will also be able to build scalable, globally distributed,<br />and highly responsive applications.</p>

Performing CRUD operations in MongoDB


MongoDB is one of the popular NoSQL databases. You need to create a MongoDB database and collection and you can do basic CRUD using the Azure Terminal in the browser, or get a connection string and connect it to your node app.

  1. Open your Azure portal and create a new MongoDB instance; refer to the following screenshot for reference:

  1. Once it is created, you can add a new collection to it. Refer to the following screenshot for reference:
  1. Now you need to retrieve a connection string. Go to the Settings | Connection String option and copy the connection string.

Note

Keep it somewhere secure and do not share it.

Now you can connect your Node.js application to this MongoDB instance using the connection string.

We are going to cover Node.js in Chapter 5, Integrating Node.js with Cosmos DB.

You can, however, do the CRUD on the Azure browser terminal itself.

  1. Click on the New document button on top of the bar and add the following JSON to create a document:
{ 
    "id":...
