Kubernetes QoS Controller: Cluster Performance & Resource Management
Qosmic is an open-source quality of service (QoS) controller for Kubernetes. It provides cluster administrators visibility into resource usage and performance, and helps ensure workload performance meets SLAs.
What is Qosmic?
Qosmic is an open-source quality of service (QoS) controller designed specifically for Kubernetes environments. It gives cluster administrators enhanced visibility into resource usage, performance characteristics, and service level objectives (SLOs).
Key capabilities and benefits of Qosmic include:
- Dashboard showing pod-level CPU, memory, network I/O, and storage usage metrics
- Ability to define SLOs for critical workloads
- Automatic pod resource adjustment to maintain SLO conformance
- What-if analysis to model infrastructure changes
- Anomaly detection to identify workloads behaving badly
- Supports defining namespace quotas and priorities
- Horizontal pod autoscaling based on custom metrics
By leveraging Qosmic, Kubernetes teams can better understand application resource demands, set performance objectives, optimize infrastructure utilization, and assure critical workloads obtain resources they need. As an open source project, Qosmic is free to use and compatible with popular Kubernetes distributions.
