A proof that Microsoft technologies can be used for ultra-large-scale systems

Here's a proof that Microsoft technologies can indeed be used to build ultra-large-scale systems: MySpace architecture.

Ultra-large-scale systems have the following characteristics, as Len Bass of Software Engineering Institure (SEI) describes here:

• They are decentralized in terms of data, development, evolution, amd operational control
• They have a wide variety of stake holders and therefore they have inherently conflicting and unknowable requirements
• They continually add new functions and content
• Software and hardware failure is a norm rather than the exception
