Building and maintaining an e-commerce platform that serves hundreds of millions of customers over multiple regions is certainly a great challenge. Doing it all in a manner that’s both pragmatic and effective – even more so. Our story at Wayfair Engineering is not a glamorous one of clouds, but instead one of grit, rolling your sleeves, iterating and innovating in a high-volume, high-concurrency, always-evolving environment. We’d like to revisit with you some of our achievements in building a platform that allows us to serve our many customers “A Zillion Things Home”, while at the same time looking to the future.
