Azure Functions description
Azure Functions lets you run small pieces of code (called "functions") in the cloud without worrying about managing servers. It's ideal for automating tasks, like processing data or reacting to events in your applications, without the complexity of building and maintaining a full application infrastructure.
Who is Azure Functions best for
Azure Functions is a serverless compute service that lets you run code on-demand without provisioning or managing infrastructure. Users love its automatic scaling and cost-effective, pay-as-you-go pricing. However, some users have noted challenges with cold starts and debugging. It's ideal for developers and businesses seeking to build and run event-driven applications, automating tasks, and processing data efficiently in the cloud.
