Book Description
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.
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.
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, and highly responsive applications.
What you will learn
- Build highly responsive and mission-critical applications
- Understand how distributed databases are important for global scale and low latency
- Understand how to write globally distributed applications the right way
- Implement comprehensive SLAs for throughput, latency, consistency, and availability
- Implement multiple data models and popular APIs for accessing and querying data
- Implement best practices covering data security in order to detect, prevent and respond to database breaches
Who this book is for
This book is intended to anyone who wants to get well versed with Microsoft's new NoSQL database called Azure Cosmos DB. Get the database into work with the practical examples mentioned.

Preface
Azure Cosmos DB is Microsoft's managed database solution for individuals and enterprise with the industry standard service-level agreement. Azure Cosmos DB provides multi-model database support that can scale across more than 30 regions across the world. Azure Cosmos DB provides a turn key distribution that enables the database admins to scale and replicate their database with a few clicks.
This book covers the major concepts and features of Azure Cosmos DB. This book also covers the development of web applications using Cosmos DB and their integration using the software development kit provided by Azure Cosmos DB.
Who this book is for
This book is intended for anyone who wants to get well versed with Microsoft's new NoSQL database called Azure Cosmos DB. You should have prior experience of dealing with any SQL or NoSQL databases.
What this book covers
Chapter 1, Introducing Microsoft Azure Cloud and Cosmos DB, aims to provide an introduction to the Microsoft Azure platform. The reader will get to know the various interfaces and modules provided by the Microsoft Azure cloud. Another part of this chapter provides an introduction to Cosmos DB, which is the main topic of the book.
Chapter 2, Cosmos DB Global Turnkey Distribution, covers one of the key features of Cosmos DB, which is its global turn key distribution system. You can replicate your database more than 30 regions scattered across the globe using a very simple interface.
Chapter 3, Cosmos DB Multi-model Databases, provides the four (five after publishing state of this book) database models that you can pick from. This chapter covers these database models in detail.
Chapter 4, Querying Cosmos DB, covers the different types of queries required for multi-model databases. This chapter segregates these queries in the CRUD (Create, Read, Update, and Delete) way to explain it better.
Chapter 5, Integrating Cosmos DB with Node.js, covers all integration with one of the popular backend runtime engines, Node.js. We have covered how to connect to the database models of Cosmos DB with Node.js.
Chapter 6, Building High-Performance Link Shortening and Tracking System Using Cosmos DB, covers the development of a simple and high-performance link shortening and tracking system that's very similar to bit.ly using Cosmos DB and Node.js. The reader will learn and relate how they can build a complex system like this using a Cosmos DB-managed database solution.
Chapter 7, Building Highly Available and Real-Time Email Tracking System Using Cosmos DB, covers the development of a system that handles the email tracking that is open rates of the email by millions of users and stores them in the database for further analytics.
Chapter 8, Cosmos DB Deployment and Management, covers all of the deployment of your custom application and Cosmos DB database to the production environment.

Introducing Microsoft Azure Cloud and Cosmos DB
The public cloud provides services such as virtual private servers and databases hosted as a service to the general public on a subscription basis. Some platforms, such as Amazon, charge an hourly subscription or offer pay-as-you use (Lambda) services, while others charge a fixed amount for a month, such as DigitalOcean, and so on. The Windows Azure public cloud platform is one of the important pillars of Microsoft's Cloud OS vision
