Acutally financial query might use this architecture, except that the significant difference between this workload and "typical commercial" workloads -- they do no updates. Therefore no data integrity issues.
Even a bankcard authorization requires the recording in a reliable way of the details of the query. And if the transaction completes, the further recording of the details attendant to the completion. Another bonus Google has is that they say they write all their own software. If that includes a modifed or proprietary opsys, no need to wory about virues, etc. Reminds me of the tradeoffs that used to tilt the balance between off-the-shelf electronics and ASICs. There is a subtext here. If their business is so unique, new entrants have a significant barrier to entry. New entrants will either have a significant upfront development cost prior to initiation of the revenue stream or will have to develop on off-the-shelf hardware/software and migrate to specialization. What I would like to see is the paper where Google talks about how to beat the "garbage-in/garbage-out" syndrome that generates a million hits on a query, most of which are commercial sites, most of which are porn sites.
