The Missing Metrics: Measuring Memory Interference in Cloud Native Systems - Jonathan Perry
Jonathan Perry
KubeCon + CloudNativeCon Europe 2025 · Session
In the increasingly complex landscape of cloud-native systems, maintaining high availability and cost efficiency while delivering superior user experience remains the "holy grail" for Site Reliability Engineers. This talk by Jonathan Perry, titled "The Missing Metrics: Measuring Memory Interference in Cloud Native Systems," addresses a critical, often invisible, threat to these goals: **memory noisy neighbors**. Perry argues that while engineers dedicate significant effort to optimize application performance, these gains can be obliterated by resource contention on shared server infrastructure, particularly related to memory caches and bandwidth. The presentation highlights that this problem, long understood and mitigated by hyperscalers, lacks an accessible, open-source solution for the broader Kubernetes community.

Perry's talk on memory noisy neighbors isn't just another KubeCon fluff piece; it's a critical exposé of a hidden performance killer and a call to action for the entire cloud-native community. He brutally dissects why current monitoring is inadequate and proposes a technically robust, open-source solution – the Unvariance collector – to bring hyperscaler-level resource management capabilities to everyone. This isn't just about optimizing; it's about reclaiming massive amounts of wasted compute and ensuring consistent performance, making it a must-see for anyone serious about operating…
