Modern web applications often require long-running tasks that need to be resilient to external errors and interruptions. If such long-running tasks aren't handled propertly, any error could lead to data inconsistencies, financial losses, poor user experiences, and overall system failures.

These are features like API integrations, AI-powered workflows, data exports, automated billing systems, user onboarding sequences, or even recurring notifications.

Durable Functions offer a simpler, more streamlined solution for managing long-running tasks that need to withstand interruptions and failures. They provide a powerful framework for building resilient, stateful applications, removing the need for manual error and retry management.
