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>

Backup and restore


Cosmos DB automatically takes backups of all your data and keeps it updated at regular time intervals. The automatic backup operations are done without affecting the performance or availability of your database operations.

Cosmos DB backups are stored separately, in another storage service, and those backups are globally replicated for high time availability and to avoid regional disasters.

The automatic backups are made for scenarios when you accidentally delete your Cosmos DB container and later require data recovery.

The automatic backups are taken every four hours and at least two copies of the latest backup are stored. If you have deleted your database and information, you can contact the Azure team within four to eight hours to get your data back!

The automatic backups are stored in the blog storage and are kept in the same region as your master data to provide high availability in the case of failure. Automatic backups are also replicated across the region, in order...
