Dapr Workflow makes orchestrating logic for messaging, state management, and failure handling across various microservices easier for developers. Prior to adding workflows to Dapr, you'd often need to build ad-hoc workflows behind-the-scenes in order to bridge that gap. Dapr Workflow makes orchestrating the logic required for messaging, state management, and failure handling across various microservices easier for developers. Dapr Workflows enable you to create long running, fault-tolerant, stateful applications. Prior to Dapr workflows you'd often need to build ad-hoc workflows in custom, hard to write code in order to achieve long running, fault-tolerant, stateful applications.
