autotune

Kruize Autotune is an Autonomous Performance Tuning Tool for Kubernetes. Autotune accepts a user provided "slo" goal to optimize application performance. It uses Prometheus to identify "layers" of an application that it is monitoring and matches tunables from those layers to the user provided slo. It then runs experiments with the help of a hyperparameter optimization framework to arrive at the most optimal values for the identified set of tunables to get a better result for the user provided slo.

Autotune can take an arbitrarily large set of tunables and run experiments to continually optimize the user provided slo in incremental steps. For this reason, it does not necessarily have a "best" value for a set of tunables, only a "better" one than what is currently deployed.

kubeip

Kubernetes' nodes don't necessarily need their own public IP addresses to communicate. However, there are certain situations where it's beneficial for nodes in a node pool to have their own unique public IP addresses.

For instance, in gaming applications, a console might need to establish a direct connection with a cloud virtual machine to reduce the number of hops.

Similarly, if you have multiple agents running on Kubernetes that need a direct server connection, and the server needs to whitelist all agent IPs, having dedicated public IPs can be useful. These scenarios, among others, can be handled on a cloud-managed Kubernetes cluster using Node Public IP.

KubeIP is a utility that assigns a static public IP to each node it manages. The IP is allocated to the node's primary network interface, chosen from a pool of reserved static IPs using platform-supported filtering and ordering.

If there are no static public IPs left, KubeIP will hold on until one becomes available. When a node is removed, KubeIP releases the static public IP back into the pool of reserved static IPs.

The case of the vanishing CPU: A Linux kernel debugging story

A mysterious CPU spike in ClickHouse Cloud on GCP led to months of debugging, revealing a deeper issue within the Linux kernel’s memory management. What started as random performance degradation turned into a deep dive into kernel internals, where engineer Sergei Trifonov uncovered a hidden livelock. His journey through eBPF tracing, perf analysis, and a reproducible test case ultimately led to a surprising fix - only for another kernel bug to surface right after. Curious, read on…

Auto-scaling with KEDA Using Custom RED Metrics from Prometheus

At the beginning of the year, we made a strategic decision to rewrite and optimize our legacy services that experience high load during peak times. Recognizing that these services don’t consistently operate under the same load levels, we opted for an auto-scaling approach. This decision was driven by two primary goals: enhancing reliability and evolving towards a more cloud-native architecture.
