How Axel Springer transformed ad monetization by migrating from client-side bidding to AWS RTB Fabric

This article describes how Axel Springer transformed its ad monetization by migrating from client-side header bidding to a self-hosted Prebid Server on AWS and AWS RTB Fabric.

• Deployed self-hosted Prebid Server on AWS Fargate with ElastiCache and CloudFront in two weeks, achieving revenue parity immediately
• Migrated to AWS RTB Fabric for dedicated, low-latency network paths between SSPs and DSPs, reducing median bid latency from 45-80ms to under 10ms
• Reduced bidder timeout rate from 8-12% to under 2% and decreased data transfer costs by 66%
• Increased yield by 2% through improved auction participation and reduced latency
• Building hybrid model combining client-side and server-side bidding with AI-powered optimization for future enhancements

Axel Springer's infrastructure transformation demonstrates how publishers can gain control, flexibility, and significant performance improvements by self-hosting bidding infrastructure and leveraging purpose-built networking solutions.
