The Register recently had an an interesting article on GFS2: the replacement for the Google File System. It offers insight on the problems Google is facing with the aging GFS. In today's world of video streaming, GMail account checking, and more, the GFS model doesn't hold up as it once did. According to the article, the new Caffeine search engine that Google is rolling out supposedly uses this new back end, resulting in faster search results. It should be interesting to see what other benefits come our way as Google tinkers with their engine.
