Consider a web server for a streamlined search engine. This system has 100 machines to reply to search queries, which may then call out to another cluster of machines using processSearch(string query) to get the outcome. Because the machine that responds to a given query is chosen at random, you cannot always expect the same machine to reply to the same query. ProcessSearch is an extremely expensive technique. Create a caching mechanism to save the most current query results. Make careful to describe how you would update the cache if data changed.
