Low-latency real-time bidding (RTB) platform on Kubernetes with ingress, bidding, caching, streaming, and observability namespaces. Traffic flows from Ad Exchange through WAF and Ingress Gateway to bidder pods, which query Redis for feature caching and Kafka for event streaming, with Flink processing and ClickHouse analytics. HPA scales bidder deployments dynamically, while OTEL collectors feed metrics to Prometheus and Grafana for full observability. This architecture demonstrates production-grade Kubernetes patterns for sub-100ms RTB decisions at scale. Fork and customize this diagram on Diagrams.so to match your RTB infrastructure topology and namespace strategy.
