MediaMath’s infrastructure footprint is reflective of the challenges of a real-time advertising
stack – a hybrid environment of multiple globally placed datacenters and the AWS cloud. We
support a broad range of services, from low latency bidding processes handling millions of
transactions per second, through to big data storage and analytics, as well as client-facing UI and
reporting solutions. Each has its own unique operational challenges, and the Infrastructure team
is a key partner in ensuring these workloads are managed in scalable, maintainable, cost-
