The following page has been changed by LarsGeorge: http://wiki.apache.org/hadoop/PoweredBy The comment on the change is: Added description for WorldLingo ------------------------------------------------------------------------------ * We use a small Hadoop cluster in the scope of our general research activities at [http://www.vklabs.com VK Labs] to get a faster data access from web applications. * We also use Hadoop for filtering and indexing listing, processing log analysis, and for recommendation data. + * [http://www.worldlingo.com/ WorldLingo] + * Hardware: 44 servers (each server has: 2 dual core CPUs, 2TB storage, 8GB RAM) + * Each server runs Xen with one Hadoop/HBase instance and another instance with web or application servers, giving us 88 usable virtual machines. + * We run two separate Hadoop/HBase clusters with 22 nodes each. + * Hadoop is primarily used to run HBase and Map/Reduce jobs scanning over the HBase tables to perform specific tasks. + * HBase is used as a scalable and fast storage back end for millions of documents. + * Currently we store 12million documents with a target of 450million in the near future. + * [http://www.yahoo.com/ Yahoo!] * More than 100,000 CPUs in ~20,000 computers running Hadoop * Our biggest cluster: 2000 nodes (2*4cpu boxes w 4TB disk each)
