Service Bus
Reliable message queue for Dataverse events. Plug-ins publish to Service Bus; downstream consumers process async. Handles retry, dead-lettering, high volume.
Event Grid
Pub/sub for event-driven architectures. Dataverse integrates natively. Cheaper than Service Bus for at-least-once, fire-and-forget scenarios.
Logic Apps
Azure’s counterpart to Power Automate — more capable, IT-owned. Complex B2B integrations live here. Shared expertise with Power Automate translates.
Azure Functions
Serverless code for custom logic. Webhook targets for Dataverse. Custom connectors back to Power Automate. Cheap, scales automatically.
When to Use Which
Power Automate for citizen-dev workflows. Logic Apps for IT-owned integration. Service Bus for durable queuing. Event Grid for routing events. Functions for compute.
