Yesterday I joined the “Building Azure Solutions” LinkedIn group. This is certainly recommendable to everyone who’s serious about learning all the ins and outs of Windows Azure. It’s got very useful links and updates on strategy and technology. It’s a really good starting point apart from the Microsoft Getting Started page.
The first thing that stands out is the link to a free Windows Azure eBook named “Windows Azure Platform: Articles from the Trenches Volume One”. It’s a collection of articles on various Windows Azure aspects.
