2 CHT Project Develop a resource management scheduling algorithm for CHT datacenter. Two types of jobs, interactive/latency- sensitive and batch/computation-intensive. Minimize SLA violation with limited resources. # of servers Based on Red Hat Openshift

3 Current Plan Two components Scheduler Container Scaler
Deploy container/pod to server Inside Kubernetes Container Scaler Decide the number of container/pod for each service. Output the results in JSON As an input of the scheduler

4 Container Scaler Decide the number of container/pod for each service according to the monitoring data. Ex: add one container if the average CPU utilization is higher than 85%. Add/adjust rules to make better decisions.

5 Adjust According to Monitor
If the QoS of an application can be measured from the monitor. Add container according to the QoS. Ex: if the average response time is over 80% of the SLA, add new container. If not, need to “derive” from the monitoring data. Ex: if the CPU utilization over 75% and the network I/O is larger than 800Mbps, add new container.

6 根據硬體資源使用率，判斷是否可減少容器數量
量測資料 資料包含效能數據 比較目前效能及 SLA 效能 > SLA*0.9 利用硬體資源使用率，推測目前效能 根據硬體資源使用率，推測增加容器數量 開始 以 json 格式寫入輸出檔 結束 紀錄服務目前容器數量 處理完所有服務 更新容器數量 根據硬體資源使用率，判斷是否可減少容器數量 F T

8 Improving the Rules Apply data analysis techniques to improve the derivation. SVM(Support Vector Machine) Find the hyper-plane that separate the data points into “safe” and “violation”. Add containers for those applications being classified into “violation”. Find another hyper-plane that separate the data points into “safe” and “over-provision”. Remove containers for those applications being classified into “over-provision”.

9 Implementation Working on container scaler with basic rules.
No data analysis techniques are involved in current state. Will coordinate the data format with Prof. Lin’s group. JSON format.
