It's an exciting time for developments in computer performance, not just for the BPF technology (which I often [write about]) but also for processors with 3D stacking and cloud vendor CPUs (e.g., In case you are interested, at the same conference I also gave a talk on [BPF Internals].

There's an arms race to add eBPF (BPF) to commercial observability products, and in this post I'll describe how to quickly do that. People like to show me their BPF observability products after they have prototyped or built them, but I often wish I had given them advice before they started. You might not even like BPF.

Back in 2015 we'd have BPF (iovisor) meetups in Santa Clara and most contributors would be there in person, with some having travelled. Linux has been described as the world's most successful open source project, and it's all engineers working remotely. I know others who have also left the Bay Area or are planning to.

To sustain this data growth at Netflix, it has deployed open-source software Ceph using AWS services to achieve the required SLOs of some of the post-production workflows. Technology advancements in content creation and consumption have also increased its data footprint.
