SWM QoS Scheduler

The SWM QoS Scheduler is an extension of the Kubernetes scheduler that implements an extended model for describing enhanced application requirements and infrastructure capabilities, according to the Seamless Computing concept. “QoS” is short for “quality of service”.

The SWM QoS Scheduler considers the extended application (QoS) requirements when placing application components (further called workloads) to compute nodes in the Kubernetes cluster. The main enhancements beyond the existing Kubernetes scheduler are:

• schedule multiple workloads (Kubernetes pods) at once, considering dependencies between these workloads
• network-aware scheduling: make Kubernetes aware of the network topology, connectivity, and resource availability between worker nodes, and consider this in the scheduling decision (according to the communication requirements of the applications)

Getting Started

For installing the SWM QoS Scheduler (including all CRDs and required containers) and to deploy a small demo application, see quick start.
