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.

By accessing the Backend settings blade, you have access to all the parameters that are used for a connection. If they are incorrect, the backend pool will report Unhealthy as the endpoint status and return HTTP 502 as a result. It is important to understand the implications of the parameters used to avoid problems with connectivity.

In the previous sections, we created an instance of Azure Application Gateway using default settings. This can cause problems as, by default, the incoming host header will not be rewritten to match a backend. To change that, go to Backend settings, select your settings, and see the Host name section:
