The Nordstrom Data Lab is building out an API that powers product recommendations for our customer online and beyond. Recommendo, our flagship product, was built from the ground up using Node.js and AWS in a little over three months. Since launch in November 2013 we've served up over three billion recommendations and survived Black Friday and Cyber Monday without breaking a sweat. We'll be sharing our learnings for building and operating a high traffic API on the AWS platform as a service focusing on Node.js, Elastic Beanstalk, and DynamoDB. Additionally we'll discuss some of the cultural challenges and opportunities presented when adopting the public cloud at a large corporate IT organization. In short, we believe there are tremendous advantages to be had for enterprises willing to make the leap to the cloud.
