Azure App Service is a fully managed platform-as-a-service solution that enables developers to quickly build and release web applications, event-driven functions, RESTful APIs, and more. The service provides dynamic scaling without worrying about provisioning and maintaining infrastructure. Recently, Azure App Service has been extended to support Linux-based environments with various runtimes such as .NET, Node.js, Java, Python, and PHP. This extension allows developers to capture distributed traces across their web applications, write and submit custom metrics, and gain quick insights into their applications' performance using the Datadog APM and Azure Serverless view. With these features, users can troubleshoot issues more efficiently by visualizing flame graph spans, tagging errorful spans, and filtering resources in the Serverless view.
