Multi-region SolarWinds Orion monitoring architecture spans five geographic regions with distributed polling engines feeding a centralized US-based database cluster. The US AVS Region hosts a three-tier architecture: load-balanced web servers (SW02750, SW03532, SW04649) in the presentation tier, primary and secondary polling engines in the application tier, and a two-node Orion database cluster (SW04578, SW04579) in the data tier. Regional polling engines in Sweden (four sets), Germany (two sets), China, and Australia collect telemetry from local infrastructure and report to the central database, ensuring low-latency monitoring across continents while maintaining data sovereignty. This hub-and-spoke topology demonstrates best practices for enterprise-scale network monitoring with redundant polling engines per region and centralized reporting.
