Погане відкриття Amazon AWS®: overselling

Це моніторинг використання процесора на екземплярі EC2 в Ірландії (t3a.xlarge). Дві речі, на які слід звернути увагу:
-the left graph has an average of 40% білого фону (вона не досягає повної міри 400% Висота процесора)
-the left graph has a maximum of 46% Крадіжка процесора (яка є червоною частиною, and it should not be above 2%).
Всього: a maximum of 86% CPU power is GONE.

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 (but it did not change anything).

Conclusion: it has been confirmed that Amazon AWS® is overselling its T-family instances since November 2022, confirmed again in March 2023, and in June 2024
