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.

Scaling Azure Functions

When using PaaS services, you can configure how your application will behave when CPU utilization hits the maximum allowed value, or the number of requests exceeds the threshold. However, Azure offers services in other models—one of the most interesting is serverless architecture, which abstracts control even more in favor of easier configuration, minimum maintenance, and the ability to focus on delivering a business value.

In this section, you will see the differences between Azure App Service and Azure Functions when it comes to scaling, both from a technical and conceptual point of view.

Scaling serverless applications

When you are using serverless services (such as Azure Functions, Azure Cosmos DB, or Azure Event Grid), you have limited options when it comes to configuring the feature. Here are some examples:

  • In Azure Functions, you rely on the pricing model (consumption...
