亞馬遜 AWS® 錯誤發現

這是愛爾蘭 EC2 實例的 CPU 監控使用方式 (t3a.xlarge). 需要注意的兩件事:
-該圖的平均值為 40% 白色背景 (它沒有達到全部 400% CPU 高度)
-最多有 46% CPU 竊取 – 這是紅色部分 (這不應該高於 2%).
總計: a maximum of 86% CPU power is GONE.
換句話說: Amazon AWS is overselling its underlying EC2 instances…

Note: for the avoidance of the doubt, the EC2 instance was stopped and started again around 6:30AM on the left graph, so the instance was running on a new hardware from 6:30AM. This has been done to also rule out any hardware or hypervisor problem.
