Explanation:

Scenario: Retail store locations: Azure Functions must process data immediately when data is uploaded to Blob storage.
Box 1: HTTP
Binding configuration example: https://<storage_account_name>.blob.core.windows.net Box 2: Input Read blob storage data in a function: Input binding Box 3: Blob storage The Blob storage trigger starts a function when a new or updated blob is detected.
Azure Functions integrates with Azure Storage via triggers and bindings. Integrating with Blob storage allows you to build functions that react to changes in blob data as well as read and write values.

Explanation:

Box 1:WebHook
Scenario: If an anomaly is detected, an Azure Function that emails administrators is called by using an HTTP WebHook.
endpointType: The type of endpoint for the subscription (webhook/HTTP, Event Hub, or queue).
Box 2: SubjectBeginsWith
Box 3: Microsoft.Storage.BlobCreated
Scenario: Log Policy
All Azure App Service Web Apps must write logs to Azure Blob storage. All log files should be saved to a container named logdrop. Logs must remain in the container for 15 days.

Explanation:

Box 1: Azure Event Grid
Blob storage events are pushed using Azure Event Grid to subscribers such as Azure Functions, Azure Logic Apps, or even to your own http listener. Event Grid provides reliable event delivery to your applications through rich retry policies and dead-lettering.
Box 2: Azure Logic App
Event Grid uses event subscriptions to route event messages to subscribers. This image illustrates the relationship between event publishers, event subscriptions, and event handlers.

Box 3: Azure Service Bus
The Event Grid service doesn't store events. Instead, events are stored in the Event Handlers, including ServiceBus, EventHubs, Storage Queue, WebHook endpoint, or many other supported Azure Services.
