Dynamically adjusting resources to meet service level objectives
The present disclosure provides for dynamic resource allocation to a container on a host. For example, in a first directed acyclic graph (“DAG”), a CPU resource usage of a container may be detected. In a second DAG, an I/O resource usage of the container may be detected. In a third DAG, a network traffic resource usage of the container may be detected. Each detected resource may be associated with a distinct control group. Each detected resource usage may be compared to a detected service level objective (“SLO”). Resources that fail to meet the SLO may be adjusted. Each adjusted resource usage may be compared to the SLO, and any resources that continue to fail to meet the SLO may be further adjusted. An orchestrator may be notified when a resource has been adjusted to a threshold limit and the container may be migrated to a second host.
