DSP Infrastructure Flow — Traffic & Data Paths

1. Overview

This document describes the DSP traffic, messaging, and data-processing flow across two infrastructure segments:

  • Leaseweb (Canada) — core DSP bidding and realtime components

  • Leaseweb (Europe) - core DSP bidding and realtime components

  • Yandex Cloud (Russia) — analytics, web, and auxiliary services

The architecture diagram is provided as a static image and embedded below.

3. Notes

  • Leaseweb hosts latency-critical RTB components and caches

  • Yandex Cloud hosts persistence, analytics, and public-facing services

  • Kafka serves as the boundary bridge between infrastructure segments

  • Arrow colors are a contract and must stay consistent across diagrams

  • Kafka clusters are interconnected via Kafka MirrorMaker (Leaseweb → Yandex Cloud, one-way replication).
