The platform is built to scale from thousands to millions of requests per second, according to the technology page.
The building blocks
- Real-time event streaming with Apache Kafka.
- In-memory and real-time data stores: Aerospike and Redis.
- Fast analytics at billions of rows with ClickHouse.
- Resilient networking and high-performance storage.
- Capacity that grows with your traffic.
Filtering before work is done
A lot of scale comes from not doing unnecessary work:
- Pre-bid filters refuse bad requests before any money moves.
- Traffic shaping on the ADX stops sending requests that no partner bids on.
- Per-partner limits keep one partner from flooding the rest.
Monitoring
The platform is monitored around the clock (24/7). Hosted plans aim for 99.9% monthly availability of the bidding and ad-serving systems, published on status.adtech.eu.
How QPS affects price
- DSP and DMP: no QPS fees and no QPS limits.
- Rented SSP or ADX: up to 25,000 QPS for $500 a month, 100,000 QPS for $1,900, 150,000 QPS for $2,900.
- License or source code: no QPS limits; bandwidth is paid to your hosting provider.
