Yelp is evolving from a purely hosted infrastructure environment to running many systems in AWS—paving the way for their growth to 108 million monthly visitors (source: Google Analytics). Embracing a cloud culture reduced reliability issues, sped up the pace of innovation, and helped them support dozens of data-intensive Yelp features, including search relevance, usage graphs, review highlights, spam filtering, and advertising optimizations. Today, Yelp runs 7+ TB hosted databases, 250+ GB compressed logs per day in Amazon S3, and hundreds of Amazon Elastic MapReduce jobs per day. In this session, Yelp engineers share the secrets of their success and show how they achieved big wins with Amazon EMR and open source libraries, policies around development, privacy, and testing.
