summary

Poseidon is a consolidated virtual network controller deployed on Alibaba Cloud for 3+ years that replaces 50+ service controllers with a unified config-and-device layer and a unified agent, uses a tree-based abstraction called Trident to map configs to device groups, and implements a function-based descendant calculation (plus reference-count variants) to avoid full traversals. Evaluation shows 21x throughput for config tasks, 4.4x lower P99 API latency, 1.8–55x faster EIP enablement versus top vendors, and 22–41% fewer lines of code, and it runs in production at million-VM VPC scale.
