With all the different codenames flying around in the lead up to PDC2008 it is easy to lose track of what’s what. Here’s a quick summary to set you back on course:

Oslo is Microsoft’s upcoming visual modelling tool. It includes Quadrant (the visual part) and ‘M’ (the modelling language, previously referred to as ‘D’). We’ve discussed Oslo in these posts.

Dublin is a set of enhanced Windows Server capabilities that extend IIS (delivered via the next versions of WF and WCF). The aim is improve deployment and increase the ease of scalability. We wrote about Dublin here.

Red Dog is the code name for Microsoft’s cloud offering for Windows Server and SQL Server. It’s been referred to as EC2 for Windows (EC2 being a reference to the Amazon offering). We wrote about Red Dog here.

Hope that helps.
