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.

Autoscaling, scaling up, scaling out

The cloud is all about scaling—it is one of the most important advantages of such a setup over an on-premises setup. The ability to rapidly adapt to new demands when it comes to incoming traffic, and the flexibility a cloud offers, enable you to create more stable services that are less prone to unexpected load spikes and insufficient hardware performance. In this chapter, we will focus a little bit on diving deeper into the scaling topic, to build a deep understanding of how different services behave in Azure, and how you can ensure that the scaling feature is automated and requires as little attention as possible.


You can define the autoscaling feature of many services as follows:

Autoscaling is a feature that allows a service, a machine, or an application to automatically scale up or out based on predefined parameters, such as central processing unit (CPU) utilization, memory used, or...
