How can I set up a CRON job using Windows Azure?

Azure does have a scheduler now.

It allows invoking a Web Service over HTTP/s and post a message to a Windows Azure Storage Queue. It's very new but it can be free if you do not need the scheduler to be executed often. Otherwise it's a small monthly fee which come with scheduled task that can be up to every minute.

Things got much easier lately, please see this link https://azure.microsoft.com/en-us/services/scheduler/ to create a scheduled job in the new Azure Scheduler. There is a basic Free tier as well as some paid options but I think this is exactly what many of us were looking for. It is an excellent solution for triggering URLs with GET,POST,PUT,DELETE requests.

Just follow the simple instructions. Starting by selecting "Scheduler" from the Azure dashboard app menu:

Google Azure Storage Queues. They allow you to schedule jobs that will run at a later date. You can even specify when the job should run.
