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.

This is a very common PaaS component that is widely used among many Azure users, both for very simple websites and complex systems requiring high performance and reliability. To make sure that your web app is always on or to check if it is under pressure, you must implement scaling rules. When it comes to this service, you have two options—either using manual scaling (and implementing an alert so that you know when such an action should happen) or an autoscale feature, which makes things much easier in terms of maintenance. In this section, we will cover and compare both.
