  * Duplicate code/businesslogic * Resource contention (engineers) * Inconsistent interfaces * Poor communication between backend and API engineers

  * All productsrun from the same API * Takes MVC to the next level, decoupling front end from back end * Enforces consistency within interfaces * Allows mobile and 3rd party clients to stay current with website * Allows for quick iterations

  * Global company,18 million items, 60 million monthly visitors, 25 million members * Etsy sellers made over 1 billion dollars in 2013 * v2 API - standard REST, clients made multiple requests for a single view * Access control added complexity * Duplicated code and business logic * v3 - domain resources, not row resources (not driven by DB schema) * scripting for more complex requests (for multiple related resources) using bespoke * Improved communication between backend and frontend engineers * Faster iterations, more confidence in API * Activity Feed went from asynchronous to on-demand, from minutes to sub-second http://www.slideshare.net/PaulWright9
