Automating File Processing with Azure Functions and Storage Blob Triggers

Azure Event Grid and Azure Functions work together to create powerful event-driven, serverless applications in Azure. Event Grid acts as an intelligent event routing service that uses a publish-subscribe model to deliver events from various sources (like Blob Storage or IoT Hub) to multiple destinations, while Azure Functions provides the serverless compute capability to process these events without managing infrastructure. When integrated, Event Grid can automatically trigger Azure Functions whenever specific events occur - for example, when files are uploaded to Blob Storage, Event Grid can detect these changes and invoke a Function to process the files, enabling automated workflows with minimal code and infrastructure management.

In this lab, you will learn how to use Azure Function and Event Grid to automate file processing in Azure Blob Storage.
