Złe odkrycie Amazon AWS®: overselling

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

To jest użycie monitorowania procesora w instancji EC2 w Irlandii (t3a xduży). Należy zauważyć dwie rzeczy:
-the left graph has an average of 40% białe tło (nie osiąga pełni 400% Wysokość procesora)
-the left graph has a maximum of 46% kradzież procesora (która jest częścią czerwoną, and it should not be above 2%).
Razem: 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…
