hii..i wanted to know which langauge has been used for developing google search engine???any idea about new products from google??
They use HTML/CSS & Javascript on the front end, most the raw coding is mostly Python and Java, the OS is a heavily modified Linux and the database is custom. The DB is scattered over a replicating cluster, it works on DocID's, Chunks and MapReduce. They also use Squid/Loadbalancers and cache servers. That's for the search, but their Ad servers, Maps etc are slightly different depending what service it's running.
I used to see an interview between google staff and journalist . ( Unfortunately I can't find out the URL. ) They said they are using python, googleserver and sometimes php, mysql, linux and other open source code. Python is used most often .
