Modelling Postgres Performance Degradation on Burstable Cloud Instances | POSETTE 2026
Discrete event simulation can model Postgres CPU-credit degradation on burstable cloud instances to shift-left performance testing before deployment.
“So actually you will go into the death spiral where it will keep on burning your excess CPU and you can't recover.”
A POSETTE 2026 talk demonstrates using discrete event simulation to model the token-bucket CPU-credit mechanics of Azure burstable Postgres instances, predicting throttling-induced 'death spiral' outages. It serves as a cheap filter to narrow configurations before running real load tests. The talk is about database/cloud infrastructure performance, not AI, so it carries little AI industry signal.
