Zero to Performance Hero: How to Benchmark and Profile Your eBPF Code in Rust

In this article, we will walk through creating a basic eBPF program in Rust. We will intentionally include a performance regression and then use profilers to locate and fix the bug. We will also create benchmarks and track them using a continuous benchmarking tool for CI.

Debugging Production: eBPF Chaos

This article shares insights into learning eBPF as a new cloud-native technology which aims to improve Observability and Security workflows. You’ll learn how chaos engineering can help, and get an insight into eBPF based observability and security use cases. Breaking them in a professional way also inspires new ideas for chaos engineering itself.

eBPF and the Service Mesh: Don't Dismiss the Sidecar Yet

While eBPF looks promising to improve service mesh sidecar proxy performance, there are other, simplier ways to improve performance. The layer 7 processing needed for service meshes is unlikely to be feasible in eBPF for the foreseeable future, which means that meshes will still need proxies.

A Gentle Introduction to eBPF

eBPF lets programmers execute custom bytecode within the kernel without having to change the kernel or load kernel modules. In this article, we will review what eBPF is, what it does, and how it works. Then, we will explain how to execute an eBPF program and provide an example of eBPF in action. Finally, we will conclude with recommendations for next steps.

Article Series: Configuration Management Tools

Configuration management is the foundation that makes modern infrastructure possible. Tools that enable configuration management are required in the toolbox of any operations team, and many development teams as well. Although all the tools aim to solve the same basic set of problems, they adhere to different visions and exhibit different characteristics.
