A BRIEF HISTORY OF AIRBNB'S ARCHITECTURE

Summary from the TLDR Web Dev newsletter

Airbnb started as a monolithic Ruby-on-Rails application and eventually moved to a Service-Oriented Architecture (SOA). The SOA approach aimed for loosely coupled services with focusing on clear data ownership, specific concerns for each service, and avoiding functionality duplication. Airbnb's migration journey involved multiple iterations, with the final version completely eliminating its monolithic architecture. Pros of SOA include increased reliability and scalability, while cons include increased development time and complexity. Airbnb also uses an in-house API framework, automated canary analysis with Spinnaker, and Powergrid for parallel task execution to support its SOA.
