Schlechte Amazon AWS®-Erkennung: overselling

An image is worth more than words: left graph – Amazon EC2 T-family instance oversold, right graph – not oversold

Dies ist die CPU-Überwachungsauslastung auf einer EC2-Instance in Irland (t3a.xlarge). Zwei Dinge, die Sie beachten sollten:
-the left graph has an average of 40% mit weißem Hintergrund (sie erreicht nicht die volle 400% CPU-Höhe)
-the left graph has a maximum of 46% CPU-Diebstahl (das ist der rote Teil, and it should not be above 2%).
Insgesamt: 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…
