【Cost Optimization】

feature: GPU graphics resource sharing and isolation
GPU graphics card sharing refers to running multiple computing tasks on one GPU at the same time. Compared with the mainstream single-container exclusive GPU, its main benefit is to improve
GPU utilization, reducing resource waste, thereby reducing financial costs, ACK agile version supports GPU graphics card sharing and isolation, supports exclusive graphics card, and shared graphics card, and allocates a certain quota of video memory. GPU resource isolation.

feature: application resource portrait
Added CPU and memory indicators, application resource specification portraits, and resource specification recommendations at container granularity, which can effectively simplify the complexity of administrators configuring Request and Limit for Pods.

feature: Support HPA elastic scaling based on custom monitoring indicators
HPA (Horizontal Pod Autoscaler) refers to automatically adjusting the number of workload Pod copies according to the rules, so as to realize the horizontal automatic expansion and contraction of the deployment, so that the scale of the deployment is close to the actual service load. The ACK agile version supports the configuration of custom indicator rules , to trigger the HPA to scale horizontally.

feature: simulation scheduling
● Realize simulation scheduling through the self-developed open source component Open-Simulator, thereby optimizing resource arrangement and maximizing cluster resource utilization. Open-Simulator is a cluster simulation component under Kubernetes. Through the simulation scheduling capability of Open-Simulator, users can create virtual Kubernetes clusters and deploy Workload resources on them. Open-Simulator will simulate Kube-Controller-Manager to generate Pod instances of Workload resources in the virtual cluster, and simulate Kube-Scheduler to schedule Pods.

feature: support conversion of ordinary clusters to edge clusters
Through openyurt-operator, the standard K8s cluster can be converted into an edge cluster, that is, the management and control cluster can be converted into an edge cluster, and output in the form of an independent edge cluster, instead of forcing the management and control components to monopolize the cluster, so as to compress the initial deployment of the center to a greater extent cost.
