The Consumption plan is specifically designed to support function apps in Azure. This plan operates on a serverless model, meaning that users are charged only for the actual runtime of their functions and the resources consumed during execution, rather than for dedicated infrastructure that is continuously running. This architecture allows for automatic scaling, meaning the platform automatically allocates resources based on the number of incoming events, providing a highly efficient means of handling variable workloads.

In the Consumption plan, developers can create event-driven applications without worrying about managing servers or infrastructure. It is ideal for scenarios with unpredictable traffic patterns, as it can scale out to handle multiple requests simultaneously and then scale down when the demand decreases.

Other service plans like Dedicated, Isolated, and Standard are generally used for web applications or APIs that require more predictable workloads and typically involve more constraints on scaling and resource management. These plans do not provide the same level of flexibility and cost efficiency specific to function apps as the Consumption plan does.
