Case Study: Realtor.com achieves real-time, scalable ad processing and faster feature delivery with Amazon Web Services

Realtor.com - Customer Case Study

Realtor.com, the official site of the National Association of REALTORS® operated by Move, Inc., needed to support rapid user and feature growth—38% year‑over‑year in early 2015 and sustained double‑digit increases. Its on‑premises data center constrained scalability, agility, and real‑time capabilities, leaving the company unable to deliver instant ad campaign updates, handle highly variable traffic patterns efficiently, or avoid rising hardware and operational costs.

Realtor.com migrated core services to AWS and built its Turbo Listings feature using Amazon Kinesis (Streams and Firehose), Redshift, EC2, and Lambda with help from AWS Professional Services. The solution enabled real‑time ad processing and billing, automated campaign lifecycle management, and elastic scaling—now supporting thousands of campaigns and tens of millions of impressions per day—while lowering development cost, speeding DevOps, and preparing the company for a full cloud migration.
