Azure Services

Azure Functions vs Azure Logic Apps

Azure Functions is a serverless compute service.

Azure Logic Apps provides serverless workflows.

Both can create complex orchestrations.

When dealing with synchronous request/response calls, that execute more complex logic, Azure Functions is the preferred option. Logic Apps is better suited for asynchronous integration and fire-and-forget messaging that requires reliable processing. When using Logic Apps, they can be perfectly extended with Azure Functions to execute stateless tasks that cannot be fulfilled by the out-of-the-box Logic Apps capabilities.
