Amazon AWS® slikts atklājums: Overselling

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

Šis ir CPU pārraudzības lietojums EC2 instancē Īrijā (t3a.xlarge). Divas lietas, kas jāņem vērā:
-kreisajā grafikā ir vidējais rādītājs 40% no balta fona (tas nesasniedz pilnu 400% CPU augstums)
-kreisajā grafikā ir maksimālais 46% CPU zagšana (kas ir sarkanā daļa, 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…
