Case Study: AdRoll reduces fixed costs 75% and operational costs 83% with Amazon Web Services

How AdRoll Lowers Costs with AWS

AdRoll is a global leader in digital advertising retargeting whose real‑time bidding (RTB) platform ingests rapidly growing volumes of user data to serve personalized ads. As daily data collection surged to about 150 TB and the platform needed to handle roughly 60 billion advertiser requests while meeting a 100 ms bid‑response SLA, AdRoll required a global, highly available, and scalable infrastructure.

AdRoll migrated its RTB stack to AWS—using EC2, DynamoDB, S3 and a mix of On‑Demand, Reserved, and Spot Instances—to run thousands of machines globally and scale capacity on demand. The move cut fixed costs by 75% and operational costs by 83%, saved nearly 80% on big‑data compute via Spot Instances, enabled 180 TB of S3 storage for under 10% of on‑prem costs, and reduced infrastructure staffing needs from an estimated 20 full‑time on‑prem engineers to just two engineers managing the AWS environment.
