Descoberta inválida do Amazon AWS®: Overselling

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

Este é o uso de monitoramento da CPU em uma instância do EC2 na Irlanda (t3a. xlarge). Duas coisas para notar:
-O gráfico da esquerda tem uma média de 40% de fundo branco (não chega ao máximo 400% Altura da CPU)
-o gráfico da esquerda tem um máximo de 46% roubo de CPU (qual é a parte vermelha, and it should not be above 2%).
No 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…
