Oakestra: A Lightweight Hierarchical Orchestration Framework for Edge Computing
summary
Oakestra is a three-tier hierarchical orchestration that aggregates clusters, delegates placement to cluster schedulers, and runs a tiny node engine, net manager and containerd-based runtime on each worker. It uses MQTT for control, per-node cached tunnels and a DNS returning two IPs per service (one closest and one round-robin) so latency-sensitive calls hit local instances while heavy work is load-balanced. Evaluation reports ~10x reduction in management CPU and ~10% faster application performance on constrained edge hardware.
