Wire the Action Layer
Logic Apps and Functions let the system execute the real steps of a process, rather than draft something for a person to act on manually.
A model that can only answer a question is a chatbot. The action layer is what turns "here's what should happen" into "this happened" — and on Azure that's usually two complementary services doing different jobs. Logic Apps is a visual, workflow-first orchestrator with well over a thousand prebuilt connectors into SaaS platforms and enterprise systems, built for the "when X happens in one system, do Y in another" pattern — reliable, auditable, and mostly configuration rather than code.
Azure Functions is the other half: serverless compute that runs your own code only when a trigger fires — a file lands, a queue message arrives, an HTTP request comes in, a timer elapses — written in C#, Java, JavaScript, Python, PowerShell, or Go, and billed only for the time it actually runs. Microsoft's current guidance recommends the Flex Consumption plan for new apps, which scales event-driven workloads automatically without provisioning a server that sits idle between events. Together, the two cover the whole action layer: Logic Apps for the connector-driven, visible workflow; Functions for the custom logic a prebuilt connector can't express.
How EWO 360° wires the action layer
We use Logic Apps for event-driven automation off Azure Event Grid — a resource changes state, a file lands, and the next step runs without anyone watching for it — and Functions for the processing a connector alone can't do, like transforming a file the moment it's uploaded. Read more about each on their own pages: Logic Apps and Azure Functions. The point of step three isn't which service does the work — it's that the recommendation from step two doesn't stop at a dashboard. It executes.
