Search and Discovery at SoundCloud

A short talk describing the evolution of the search and discovery infrastructure at SoundCloud.

• A description of some of the problems we encountered in the original, organically-developed search architecture, and how they were solved via the greenfield development of a new architecture based on ElasticSearch.
• A description of how we perform relevance ranking for search results, and how we can extend that ranking for other product features.
• An overview of SoundCloud's Service-Oriented Architecture approach to building complex systems.

Ideally, the talk would conclude with plenty of time for Q&A.
