+## Function App Hosting Options 
+
+> In the context of Azure Function Apps, a `hosting option refers to the plan you choose to run your function app`. This choice affects how your function app is scaled, the resources available to each function app instance, and the support for advanced functionalities like virtual network connectivity and container support.
+
+> [!TIP]  
+> - `Scale to Zero`: Indicates whether the service can automatically scale down to zero instances when idle.  
+>   - **IDLE** stands for:  
+>     - **I** – Inactive  
+>     - **D** – During  
+>     - **L** – Low  
+>     - **E** – Engagement  
+>   - In other words, when the application is not actively handling requests or events (it's in a low-activity or paused state).
+> - `Scale Behavior`: Describes how the service scales (e.g., `event-driven`, `dedicated`, or `containerized`).  
+> - `Virtual Networking`: Whether the service supports integration with virtual networks for secure communication.  
+> - `Dedicated Compute & Reserved Cold Start`: Availability of always-on compute to avoid cold starts and ensure low latency.  
+> - `Max Scale Out (Instances)`: Maximum number of instances the service can scale out to.  
+> - `Example AI Use Cases`: Real-world scenarios where each plan excels.
