Which Azure compute service is ideal for event-driven tasks with no infrastructure to manage?

Azure Functions is the ideal choice for event-driven tasks with no infrastructure to manage. It's a serverless compute service that allows you to run small pieces of code ("functions") in response to events, without having to provision or manage servers. You only pay for the compute time your code consumes. Azure Kubernetes Service (AKS) is a container orchestration service, requiring more management than serverless functions. Azure Virtual Desktop provides a virtualized desktop experience, not a compute service for event-driven code. Azure VM Scale Sets allow you to deploy and manage a set of identical virtual machines, which involves significant infrastructure management.
