Amazon AWS® slegte ontdekking: Oorverkoop

This is the CPU monitoring usage on an EC2 instance in Ireland (t3a.xlarge). Two things to notice:
-the left graph has an average of 40% of white background (it does not reach the full 400% CPU height)
-the left graph has a maximum of 46% CPU steal (which is the red part, and it should not be above 2%).
In total: 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
