网上看到的amazon题，感觉比较开放。大家有什么思路么。
Imagine you have a database that can only do 2,000 queries a second. Your
web application gets 5,000 queries a second, what can you do to improve the
situation? Follow up: Imagine its a stock quote engine for NASDAQ and that
the queries are about the top 100 stocks at closing.
Imagine you have a big online storefront. Your webserver can only do 1,000
concurrent requests. Many people are visiting your website and you want to
support 3,000 concurrent requests. What would you do? The limitation is
computational power and not bandwidth.

a quick thought:
1) aggregate the queries if there are duplicate queries
2) cache the query results and saying to customer quote might delay at most
xxx min (just as google finance)
just my 2 cents
