romefor4, thank you for your comments! Much appreciated, and I'm glad you liked the article.

Azure can be used for such a broad range of possibilities that I don't think my article would do proper justice as a 'getting started' guide. I'm by no means an expert on networking, and I haven't tried it with my set-up, but point-to-site, as I understand it, is allowing a single machine access to your network by using certificate authentication. I'd recommend downloading the ebook mentioned in the preparation section. It covers virtual machines, networking (including setting up point-to-site), storage, and a lot more.
