System Architecture

Every breakage is an opportunity to make our systems more resilient. After leading hundreds of incident reviews, I realize that each review can be reduced down to three simple questions. In this post I’ll go over why these questions are exhaustive and what common tactics come from answering these questions.

When system architects sit down to design their next platforms, they start by looking at a bunch of roadmaps from suppliers of CPUs, accelerators, memory, flash, network interface cards – and PCI-Express controllers and switches. And the switches are increasingly important in system designs that have a mix of compute and memory types and for

Imagine you are working on a shipping service that exposes an API, and whenever an order is paid successfully, the mentioned API is called…

The N+1 query problem is a performance issue you might face while building APIs, regardless of whether they're GraphQL or REST APIs. In fact, this problem occurs when your application needs to return a set of data that includes related nested data – for example, a post that includes comments.

JSON and relational tables have their strengths and drawbacks. How can you best harness those strengths in your work, while offsetting the drawbacks?

In the first of two combined BPF and filesystem sessions at the 2023 Linux Storage, Filesystem, Memory-Management and BPF Summit, Hou Tao introduced his BPF iterators for filesystem information. Iterators for BPF are a relatively recent addition to the BPF landscape; they help BPF programs step through kernel data structures in a loop-like manner, but without running afoul of the BPF verifier, which is notoriously hard to convince about loops.
