SLO-Aware Graph Forecasting for Intelligent Autoscaling in API and Microservice Backends

SAGF (SLO-Aware Graph Forecasting), an integrated prediction-and-control framework for proactive autoscaling, encodes six per-service metrics on a spatio-temporal call graph, predicts per-service SLO risk via GCN with temporal gating, and feeds these scores to a constrained RL controller for dependency-aware scaling.
