SoundCloud revitalized its search and discovery features by investing in greenfield development of a new search infrastructure. You'll learn how we evolved that infrastructure, from a main application tightly coupled to Solr, to a loosely-coupled, service-oriented architecture backed by ElasticSearch. The talk also describes how we perform relevance ranking on our corpus, using a specialized version of PageRank.

Keywords: ElasticSearch, service oriented architecture, SOA, PageRank, scaling

Target audience: Developers faced with daunting growth projections, and/or anyone curious about service-oriented architectures at scale.
