My personal opinion is that I don't see a widespread need for more capacity given horizontal scaling and servers that can already exceed 1 Tbyte of DRAM; bandwidth is also helpful, but I'd be concerned about the increased latency for adding a hop to more memory.

In 2020, Wink suddenly applied a monthly service charge; if you didn’t pay, the device would stop working. Also in 2020, Sonos caused a stir by saying they were going to “recycle” (disable) old devices. Until we acknowledge that hardware put in a home is different from a cloud service, we will never get it right.

HTML, CSS, images, and fonts can all be parsed and run at near wire speeds on low-end hardware, but JavaScript is at least three times more expensive, byte-for-byte. If you or your company are able to generate a credible worldwide latency estimate in the higher percentiles for next year's update, please get in touch.

This metric is important, but quite vague because it can include anything — starting from server rendering time and ending up with latency problems. All of this means that it will be more costly because of the growing hardware requirement and a little bit faster.

They are mostly customer stories, encouragement to move to Graviton, and minor tweaks to the AWS sustainability story that I originally wrote for the Well Architected Guide in 2020 (it was first released over a year later). It’s possible to get energy data in real time from NVIDIA GPUs (because NVIDIA provides it) but not from AWS hardware.
