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. Apps may run 2x to 10x slower, or worse.

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.,

It's an important vendor-neutral space to share the latest in technology. USENIX has been a great help to my career and my employers, and I hope it is just as helpful for you. And now, helping bring USENIX conferences to Australia by giving the first keynote: I could not have scripted or expected it.

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). And namespaces, used for Linux containers, are also a relevant technology.
