Understanding Azure Functions

Azure Functions is a cloud-based service that offers on-demand infrastructure and resources required to run applications. With functions, developers can concentrate on the essential code while leaving the rest to the service, which is continually updated. Azure functions offer four types of durable functions: activity, orchestrator, entity, and client.

Functions deliver serverless computing for Azure and can be utilized to create web APIs, manage message queues, handle database changes, process IoT streams, and much more. This platform enables developers to code in their preferred language, thus increasing productivity while ensuring reliable and scalable applications.
