I didn't pay too much attention to HyperV until I started playing around with Team Foundation Server 2010. You might ask, what does an ALM tool have to do with virtualizing servers? Well, one things we found really helpful when doing automated testing, was this...you use the lab manager to spin up all your testing environments in hyperV then when a defect is encountered, the developer can spin up that environment on their laptop and actually debug defects on the server to make sure they have the most accurate test case. This eliminates the issue of "Works on laptop, don't work in test environment".

Besides that, Microsoft's virtual stuff is pretty decent, especially when it ties in their other products.

It will play into the Azure platform if it's a pure service. You can run an application on Azure with a SQL backend, and have this new compiler service build it for you.

Although from the article, I didn't even get a sense of that being the purpose. From what i was seeing, it's just a service you can run while developing that will give you more insight into the compiler's workings. You access it via VS2010 like you normally do.

I'm curious how this would play into TFS as well, if you could get more information to be pumped out from MSBuild to some sort of report.

As a developer I mostly focus on MCPD's for whatever area I'm working on. .Net or Sharepoint. I then fill in MCTS's in the gaps for technologies like SQL Server and Biztalk.

For system engineers there are specific exams too.

PMP is also a standard cert for management. I think most consultants/programmers should take this to understand the basics of how a project is put together.
