Earlier quoted context omitted.

When did people on this site start using the word "modulo" for something other than the modulo operator in mathematics?

The weird thing is I feel "minus" makes more sense. Isn't "modulo" remainder? Whereas you're talking about the part that's left out, rather than the part that is remaining?

It's not just taking away 1 x though; modulo is "if x weren't a factor"

We (Cloudflare) have largely stopped talking about the 'edge' for some of the reasons cited in the article. 1. No one actually knows where it is or what it means. 2. It conjures images of classical ‘edge compute’ use cases like the self driving cars in the article. Those use cases tend to be exceptionally specialized (or just silly). 3. Edge implies a core or origin exists, and maybe it doesn’t need to. We would rath…

It is interesting to see that as technology advances, predictions of the past become more and more true, though they may not necessarily look like what the predictors originally thought.

In this case, I think of the network is the computer. It's been for a while, but not yet completely, but it's becoming even more so as time passes.

OH, so you're saying in a % b = c it refers to b rather than to c? That would make sense... I always just read it as "remainder" in which case it would refer to c...

I was used it in math undergrad 18 years ago, so it isn't an invention of hacker news

It’s been in the Jargon file for a few decades...

For the record according to this link, https://aws.amazon.com/about-aws/global-infrastructure/ AWS operates in 18 geographies (called) regions... These are not data centers. There are 55 availability zones (AZs) at AWS regions, and each AZ has at least 1 data center..12 more AZs at 4 more regions are also announced

Also, there are over 100 AWS CloudFront POPS:

And you can do compute in CloudFront POPS with Lambda@Edge:

> "Edge Caching" it simply refers to the Amazon datacenter closest to whoever requests the site I can't speak for AWS, but for GCP there are many more Edge and CDN points of presence than there are datacenters: https://cloud.google.com/about/locations/ (flip to Network tab in map) And in Google's case "Edge" simply means where you exit the public internet and get on to Google's own network: https://peering.google.com…

It's still a "datacenter" though, right? Just a smaller one. It's not a "region" i.e. there's no other services available other than cloudfront (and I guess lambda@edge). Or do you mean they might not be owned by aws (or Google)?

Not really. Google literally just sends ISPs some servers stick into their racks with other networking equipment. These are very "scrappy" compared to what people think of as data centers, but if a room with some network cables, an AC, and a rack counts as a data center... then sure, they're datacenters ;)

> Once registered and qualified by Google, we will send you a simple agreement for joining the GGC program. After you have electronically signed this agreement, Google will ship you servers that you install in your facility and attach to your network. Google will work with you to configure the servers and bring them into service.

Data center is a meaningless term these days, and varies by context.

It can be multiple buildings over a few square miles forming a resilient "region", or a single building, or all the way down to just some servers running in some rented rackspace in someone else's colo.

All the major clouds rent space like that for their CDN and smaller pops, and sometimes they even start smaller regions that way until they acquire or build their own structures.

Does anyone know what visualization tool the author used to create the AWS architecture diagram? It looks really cool.

What's kinda mind blowing is that this is an actual business. I can't imagine why someone would need this specifically for their cloud presentations. Like isn't visio enough for everything?

Slight devil's advocate episteme: what about an even-further generalization? How about: the market is the computer?

Not only is the network essentially imbricated with/in the market, but recognizing the market in the role of the computation also means recognizing the roles of all of the different functional components, not just the mechanical/computational "atoms". Basically, I think that thinking this way lets us treat supply-demand basically as a messaging layer.
