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). They use third-party software like Docker or Kubernetes to simplify their administration. People rarely create them manually.

This blog was originally published in October 2017 and was updated in September 2023. Vertical scaling is also often discussed, which involves increasing the resources of a single server, which can have limitations in hardware capabilities and become costly as demands grow. An example is running MongoDB on Mesos.

I recently profiled a page on a Pixel 2 (released in 2017), and an Alcatel 1x (released in 2018). Hardware gets better, sure. Software teams can reduce the environmental impact of device manufacturing, even if they don’t make devices themselves. The two devices represent very different ends of the spectrum. It makes sense.
