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. The latest AWS hypervisor, Nitro, uses everything to provide a new hardware-assisted hypervisor that is easy to use and has near bare-metal performance. I'd expect between 0.1%

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). Appliance manufacturers hire kernel engineers to develop custom features, including storage appliances.

This method distributes data evenly across partitions to achieve balanced storage and optimal query performance.

TL;DR: A lot has changed since 2017 when we last estimated a global baseline resource per-page resource budget of 130-170KiB. A then-representative $200USD device had 4-8 slow (in-order, low-cache) cores, ~2GiB of RAM, and relatively slow MLC NAND flash storage. Hardware Past As Performance Prologue. The Moto G4 , for example.

In April 2017, Amazon Web Services announced that it would launch a new AWS infrastructure region Region in Sweden. If the solution works as envisioned, Telenor Connexion can easily deploy it to production and scale as needed without an investment in hardware. Our AWS Europe (Stockholm) Region is open for business now.

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. Ballooning bandwidth and storage have fostered complacency that we can do without. The two devices represent very different ends of the spectrum. It makes sense. Performance is conservation.
