Hardware virtualization for cloud computing has come a long way, improving performance using technologies such as VT-x, SR-IOV, VT-d, NVMe, and APICv. At Netflix, we've been using these technologies as they've been made available for instance types in the AWS EC2 cloud. I'd expect between 0.1% small (thanks @cperciva ). ## 3.

This blog post shows how to connect the dots from the worst case scenario (a kernel panic) through to Kubernetes (k8s) and eventually up to us operators so that we can track how and why our k8s nodes are going away. Nodes can go away for any reason, especially in “the cloud”. Where are they going, exactly? Why did they go away?

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., This was a chance to talk about other things I've been working on, such as the present and future of hardware performance. Ford, et al., “TCP

Perhaps there's a better solution, but I've been iterating on content and templates by firing up a linux terminal on my 2017 Pixelbook and starting the built-in 11ty filewatcher and browser sync tools. Skipping to the punchline, my blog builds 35% faster and Frances' is north of 40% faster. Writing build/feed/feed.xml from.

Linux has been adding tracing technologies over the years: kprobes (kernel dynamic tracing), uprobes (user-level dynamic tracing), tracepoints (static tracing), and perf_events (profiling and hardware counters). The way the cloud is used helps with security: most instances at my employer have only been up for one or two days.
