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?

Wow! So the original story is written on the blog of a company that is creating Chart of clouds architectures (and probably being on the edge)? I'm amazed by how niche that business is!

also very nice plug to put your diagrams into the story

> When e.g. AWS Cloudfront, Amazon's Content Delivery Network talks about "Edge Caching" it simply refers to the Amazon datacenter closest to whoever requests the site. Kind of? If by "datacenter" they mean the things they said earlier that AWS had 18 of, then no, not really. There are many more Cloudfront points of presence that there are AWS regions (over 100 of the former). In practice unless someone lives very cl…

It seems a bit nit-picky, but AWS has ~18 commercial regions, but far more datacenters. It's availability zone that's a data center (more or less), not a region. So for each region you end up with 3 to 5 data centers or something like that.

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 tr…

That fails the sniff test. Markets are made up of agents that want things. Computers only want what humans say they should want, so computers are simply the agents of humanity. You can't abstract out supply and demand, at least, not forever. Abstraction is something you do to things so that you don't have to cognitively deal with them, they're predictable. Humans will act predictably for as long as it makes sense for…

The anecdote at the start of the article seems to me to suggest the investor talked about "being at the edge of science" or technology - i.e. doing something disruptive and new. But the rest of the article talks about the location of data and servers and it's relationship with the word "edge". Am I missing something? Why is the anecdote unrelated to the article?

(Author here) sorry about the confusion, I can see where you are coming from. But yes, the investor was very much enquiring about whether it is on "the edge" in a cloud computing sense. Having said that, it's important to stress that many - in fact, most - of the VCs I've talked to were amongst the most impressive, accomplished, knowledgeable and intelligent people I ever had the pleasure to work with.

There is, however, a (growing?) number of VCs with a purely financial background that approach investment decisions by establishing a framework of future trends/ developments (Crypto, Blockchain, Edge, Sharing Economy, E-Mobility and so on) and then vet potential investments based to how well companies align with these trends as well as basic suitability criteria (founding team, execution, traction etc.)

This isn't a bad thing per se as it might add a less biased view to investment decisions than the one made by the tech-founder-funds-tech-founder echo chamber, but it can lead to the level of detachment with the fundamentals of what one's talking about displayed in this article.

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…

Yes. You do not do hard real time over the public Internet.

(I've actually had the experience of driving a full-sized vehicle over WiFi. When we built our DARPA Grand Challenge vehicle in 2004, we had the test capability of driving it remotely over WiFi, from a control station with a game steering wheel and pedals. Worked fine technically, difficult to drive. 100ms of no signal and the stall timer slammed on the brakes. Self-driving in the "cloud" is not where you want to go.)

Valid points, i meet customers with vague definitions of edges and help them understand that in the age of hyper convergence, it is the least of your worries. Better focus on the stack that is going to run on the system.

> Cynics might of course argue that we have come full circle, from thick client to cloud back to thick client, but that would miss the point of what "the edge" is all about ... You don't have to be cynical -- merely to have either been in, or have read about, IT trends over the past few decades would suffice to understand that it's all cyclical. The cynical observation is that fashionable management trends and/or the…

We already reached full circle when went from mainframe to cloud.

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

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 don't think speech is mathematical, rather the opposite if anything. In a equivalent b modulo c the c is the modality, the property or condition we are interested in. The use in English is different to math's, because Natural languages are like mathematics modulo the rigidness. A category theorist would say isomorphic upto.

Here're two quotes taken from wiktionary

> Thus, the underlying structure which I would assign to Navajo will be identical, modulo word order, to the one that we found to be projected in all of the languages studied in chapter 3. 1990, Margaret Speas, Phrase Structure in Natural Language, p. 281

> Moreover, in the role of consumer, each individual (modulo his location) faces the same array of goods and services on sale to anyone who can pay the purchase price[.] 2002, Richard Arneson, "Egalitarianism", in The Stanford Encyclopedia of Philosophy

Mathematically, these expressions could be modeled in a vector space where "word order" or "location" are dimensions that are ignored. It's somewhat like saying: left and up are the same modulo rotation; [1 1 0] and [1 1 4] are the same modulo [x y lim(z->0)], if that makes any sense.
