Overview of this book

Microsoft Azure is currently one of the fastest growing public cloud service providers thanks to its sophisticated set of services for building fault-tolerant and scalable cloud-based applications. This second edition of Azure for Developers will take you on a journey through the various PaaS services available in Azure, including Azure App Service, Azure Functions, and Azure SQL Databases, showing you how to build a complete and reliable system with ease. Throughout the book, you’ll discover ways to enhance your skills when building cloud-based solutions leveraging different SQL/NoSQL databases, serverless and messaging components, containerized solutions, and even search engines such as Azure Cognitive Search. That’s not all!! The book also covers more advanced scenarios such as scalability best practices, serving static content with Azure CDN, and distributing loads with Azure Traffic Manager, Azure Application Gateway, and Azure Front Door. By the end of this Azure book, you’ll be able to build modern applications on the Azure cloud using the most popular and promising technologies to make your solutions reliable, stable, and efficient.

Partitioning, throughput, and consistency

Now we have learned something about Azure Cosmos DB – how it works and its most common features – we can focus a little bit on three important topics in this service, namely partitioning, throughput, and consistency. These factors are crucial when selecting a database engine to power your application. They directly tell you how it will be performing, how many requests it will be able to handle, and what guarantees apply when it comes to your data integrity.

Partitions in Azure Cosmos DB

Partitioning is directly connected with scaling in Azure Cosmos DB, as it allows for load-balancing incoming requests. In fact, there are two different types of partition in this service:

  • Physical: These are a combination of fixed storage and variable amounts of computing resources. This type of partition is fully managed by Cosmos DB – you cannot directly affect how your data is physically partitioned and how a service handles...
