The introductory offer includes a huge 750 hours of compute time – which rather nicely is how much you need to run a node 24x7 for the whole month. Another great reason to sign up for an MSDN subscription or to join BizSpark if you are a Software Startup.
NB: SQL Services is SQL Azure. I guess the naming change slipped through the review process for the site.
