Airbnb at Scale

In 2018, Airbnb embarked on a high-stakes journey to transform our technology architecture from a monolithic Ruby app to a more scalable Service-Oriented Architecture (SOA). Three years on, we are in a good place to look back at what we have accomplished and reflect on where we are. In this talk, I will walk through what it takes to decompose a large and complex monolith into independent, performant services, and how we continue to evolve and scale the new architecture with our changing business needs. Specifically, I will cover the methodology and tools we have used to facilitate the migration, as well as strategies to platformize our new architecture to support new business needs. Last but not least, I will share some SOA best practices that we have learned from our experience.
