Abstract
How to evaluate the performance variations of large-scale cloud data centres is challenging due to diverse nature of cloud platforms. Classic methods such as profiling-based evaluating methods tend to only provide global statistics for a system compared with cloud tracing based approaches. However, existing tracing based research lacks a systematic comparative multiview analysis from architecure-view to job-view and task-view, etc.to evaluate cloud performance variations, together with a detailed case study. We introduce MuCoTrAna, a multiview comparative workload traces analysis approach to evaluate the performance variations of large-scale cloud data centres which assists the cloud platform performance managers and big trace analysts. The efficiency of the proposed approach is demonstrated via case studies in Alibaba 2018 trace and Google trace. The multifaceted analysis results of traces reveals the qualitative insights, performance bottlenecks, inferences and adequate suggestions from global view, machine view, job-task view, etc.
