Description:

The AppNexus platform is a complex machine with many moving parts. Over 40 billion ads are served automatically each day based on rules set up by clients through the API. Many complex objects are exposed to allow clients to optimize money spent and earned on the platform. The breadth and depth of features has caused the API to grow into a monolithic application. When people talk about micro services, they typically speak about simple examples and theoretical use cases. Tackling an easy problem with any architecture is going to be simple, but what about when you have a complex system where consistency is critical? How about when mishandling a client's update can cost millions of dollars in a matter of minutes? In this presentation, Larry Finn will discuss the challenges of migrating from a monolithic to micro service architecture. He will share the open source software his team leveraged along with the tools and processes they created to make such a drastic change possible. Using real world examples, Larry will illustrate the complexities of such a migration.
