In the light of this article, Google should have a play area with only limited network and processing power for publishing betas of new products. For example, anything that's Google Search or GMail or similar must meet some performance, stability, and realiability criteria but those applications would also get to run on the big clusters. Conversely, it wouldn't matter if a beta-toy is a bit buggy or hogs down the servers on the playground since it's just playground. Some users would bear with the unfinished tone and start using the apps there, and at times it would happen that one application would gain lots of momentum, and Google could consider fixing and lifting that one to the full service level.
