Which service runs event-driven code in response to Azure Storage changes without requiring you to manage infrastructure?

Azure Functions is a serverless compute service that allows you to run event-driven code without provisioning or managing infrastructure. It's ideal for scenarios like responding to changes in Azure Storage (e.g., a new blob being added). Azure Logic Apps is a serverless workflow service for orchestrating business processes, not primarily for running custom code. Azure Virtual Machines require you to manage the underlying infrastructure. Azure Batch is for large-scale parallel and high-performance computing, not typically for event-driven, small-scale code execution.
