Ant Group Launches Cloud-Native Intelligent Capacity Tool Kapacity V0.2
-
Ant Group announced the release of Kapacity V0.2, an intelligent cloud capacity technology tool designed to address cloud-native capacity challenges. This version introduces Ant's self-developed AI algorithm for 'traffic-driven replica prediction', achieving production-grade predictive elastic scaling.
Additionally, this version supports custom metrics and is compatible with Prometheus Adapter configurations, allowing users to directly apply their existing custom metric HPA configurations to Kapacity.
Predictive scaling offers advantages over reactive scaling by proactively responding to traffic changes, maintaining stable resource levels, and achieving higher resource utilization precision. Kapacity employs a traffic-driven replica prediction algorithm that transforms replica prediction into a traffic forecasting problem. It uses linear and residual models to learn the relationship between traffic, capacity, and replica count, enabling accurate replica prediction.
Kapacity also provides custom metric support by extending the Metrics API and integrating with Prometheus Adapter, delivering capabilities for historical querying of general metrics and workload-dimensional aggregated queries.
