High-Performance Prebid Server for AdTech Industry

Project Overview

We partnered with a leading adtech industry company to develop a custom prebid server application that would serve as a gateway between publishers and demand partners. The client needed a high-performance solution capable of handling millions of bid requests daily with minimal latency.

The Challenge

Our client faced several challenges with their existing prebid infrastructure:

• Scalability issues during traffic spikes
• High latency affecting bid success rates
• Limited integration with demand partners
• Difficulty in monitoring and optimizing performance
• Complex deployment and maintenance processes

Our Solution

We developed a custom prebid server application that acts as a bid request processing gateway. The system receives bid requests from publishers via API endpoints and efficiently distributes these requests to multiple demand partners to serve ads.

Key features of our implementation include:

• Horizontally scalable microservices architecture
• Optimized request routing and load balancing
• In-memory caching for frequently accessed data
• Asynchronous processing for non-critical operations
• Real-time monitoring and alerting system
• Comprehensive analytics dashboard

Technical Implementation

Our engineering team implemented the solution using the following technologies:

• Node.js and Go for high-performance API endpoints
• Redis for caching and rate limiting
• Kubernetes for container orchestration
• Prometheus and Grafana for monitoring
• Kafka for event streaming
• PostgreSQL and TimescaleDB for data storage

We implemented several optimizations to achieve the 170ms response time:

• Connection pooling to reduce overhead
• Request batching for efficient processing
• Parallel bid request processing
• Intelligent timeout management
• Geographic distribution of server instances

Results

The custom prebid server has been a tremendous success, delivering:

• Processing capacity of 7 million requests per day
• Average response time of 170ms
• 99.99% system uptime
• 30% increase in fill rates
• 25% improvement in CPM rates
• Seamless integration with 15+ demand partners

Client Testimonial

"The SAS CUBE team delivered a prebid server solution that exceeded our expectations. The system's performance and reliability have significantly improved our ad serving capabilities and ultimately our bottom line. Their technical expertise and attention to detail were evident throughout the project."

Conclusion

This case study demonstrates our ability to develop high-performance, scalable systems for the adtech industry. By understanding the specific challenges of prebid server architecture and implementing innovative solutions, we were able to deliver a system that processes millions of requests daily with exceptional speed and reliability.
