The document discusses Azure WebJobs, which allow running scripts and programs in the Azure cloud to perform backend tasks like processing files and interacting with services. An Azure WebJob can run on a schedule, continuously, or be triggered by events. They provide a way to offload processing tasks from a web application and take advantage of Azure services. The document provides information on how to create, deploy, and debug .NET WebJobs, including using features like queues and SignalR.

Who| What | When | Where | Why | HOW | OMG WHY?!
static void Main()
{
var host = new JobHost();
host.RunAndBlock();
}
public static void AzureQueue([QueueTrigger("myqueue")] string userJson) {}

//IN WEBJOB CLASS
public static Person LastPerson { get; set; }
public static void SbQueueObject([ServiceBusTrigger("sbobjectqueue")] Person person)

}
//INTEST CLASS
[Test]
public void PersonSetsLastPerson()
{
var dawn = PersonCreator.CreatePerson("Dawn");
ImageProcessing.SbQueueObject(dawn);
Assert.AreEqual(dawn,ImageProcessing.LastPerson);
}
