Introduction
Koordinator is a QoS-based scheduling system for Kubernetes designed to improve runtime efficiency and reliability for both latency-sensitive services and batch jobs. It provides unified resource control and scheduling policies to reduce interference between containers, increase node utilization, and simplify resource configuration and tuning.
Key Features
- QoS-driven scheduling policies to optimize workload placement and interference isolation.
- Automated resource awareness and adjustment to improve cluster density and utilization.
- Modular design for easy integration and upgrade on existing Kubernetes clusters.
Use Cases
- Latency-sensitive online services (microservices, web services) that require stable performance guarantees.
- Large-scale batch/AI training jobs co-located with other workloads needing isolation and scheduling optimization.
- Production environments that require unified strategies to simplify resource tuning and cost optimization.
Technical Highlights
- Implements scheduling and resource controls using Kubernetes native extension points, compatible with common CNI/CNI plugins and scheduler extensions.
- Supports multiple metrics collection and policy plugins, enabling customizable scheduling rules per workload needs.
- Community-driven open source project under Apache-2.0 license, suitable for enterprise adoption and extension.
