Better latency with fewer servers: avoiding RAM noisy neighbors

In cloud-native environments, application performance often degrades due to contention over shared resources such as CPU caches and memory bandwidth. Current container technologies do not isolate these resources, which compels operators to maintain low utilization by scaling out their deployments.

This session will show how memory noisy neighbor degrades application performance, survey strategies used in production by Google and Alibaba Cloud to mitigate such performance interference, and discuss community efforts, highlighting the memory-collector observability project.
