Can you help me to decide which version of windows to use? Any actual performance comparisons?
I am going to setup number of servers (2-10) to host asp.net mvc application in Amazon EC2 with Load balancing and I am thinking on using micro instances because of relatively high processor power. Database is be hosted on separate more powerful instance type (High-cpu medium instance), so only software on those servers would be IIS, Workstation services (to connect to network drive) and ASP.NET.
Can you please help me decide which windows to choose - 2008 or 2008 R2 for such "blade" machines?
On one hand i want to go with 2008 R2 because it should have better performance with asp.net mvc application. On other hand, R2 can be only 64 bit and Micro instance has only(!) 613 MB of memory.
