Essentially it's based on experiences of scaling up CF installations for customers, and for the public service version (Pivotal Web Services).
A high-intelligence controller turns into a giant "god object". It attracts new functionality like a magnet. Everything depends on it and it has to know everything about everything.
In practice it begins to be both the leading cause of failure and the main scaling bottleneck.
The auction-based model allows any number of auctioneers and executors to participate without any one component needing global state.
Essentially, we rediscovered the economic calculation problem. And we're solving it by distributing knowledge across the system and letting agents solve their own problems locally.
