The Azure WebJobs SDK is a framework that simplifies the task of writing background processing code that runs in Azure. The Azure WebJobs SDK includes a declarative binding and trigger system that works with Azure Storage Blobs, Queues and Tables as well as Service Bus. The binding system makes it incredibly easy to write code that reads or writes Azure Storage objects. The trigger system automatically invokes a function in your code whenever any new data is received in a queue or blob.In addition to the built in triggers/bindings, the WebJobs SDK is fully extensible, allowing new types of triggers/bindings to be created and plugged into the framework in a first class way. See Azure WebJobs SDK Extensions for details. Many useful extensions have already been created and can be used in your applications today. Extensions include a File trigger/binder, a Timer/Cron trigger, a WebHook HTTP trigger, as well as a SendGrid email binding.
