Recently I came accross a fabulous presentation on Azure. By now, you are going YAAP, which stands for “here he goes on Yeat Another Azure Presentation”. Trust me on this, ok? The presentation was done at last TechEd by Mark Russinovich (the guy that started Sysinternals and is now an Azure Architect). If you ever seen one of his presentation, you know that he usually goes deep, but they are always very good presentations. This one, presents you the working blocks of Azure, including some demos on how things happen behind the curtain.
