Well, I'm really ignorant, when it comes to meaningless sentences like organisation and about being able to abstract logical servers away from physical hardware. You're probably right. On the other hand, I'd been involved in a few projects, which includes optimization of a big centralized databases, so, I think, I know a bit about flows of data, access patterns and where the bottlenecks are (hint: around serializing and scheduling low-level I/O operations). Try to look under the surface structure, which plain words are.)
