Node.js : Non-blocking thing
-
To Node.js Or Not To Node.js - David Haney - Blogging my experiences as a developer and engineering manager.[^] This is a great read. I don't know on what basis lots of reviews were shared in tech-websites, highlighting node's superior scalability and performance over .net/IIS , Php/Apache. They quote a lot of companies who took advantage of moving to Node. But the above article explains things neat. I might do a benchmarking myself to see it in action.

He uses the canonical example of launching a webserver in node, and compares that to:
Want to do the same thing in .NET? Be prepared to learn about IIS, the Machine.config, the Web.config, the Process Model, how Global.asax works, either ASP.NET MVC or WebForms (huge paradigms in themselves), and how Visual Studio works
That's rather unfair, and you can do without most of it.

They did. Have you looked into the OWIN stack yet? This is something that Microsoft invested very heavily in with .NET Core. Check out the Kestrel web server[^].

Wow, thanks for the pointer, Pete. I've been getting to see this name "Kestral", but was not getting a chance to look at it. This feels great. I've spent enough time learning Microsoft stack, still not an expert. But it's a tiresome thing for me to learn anything non-microsoft. When I get to see something so "great" & that's not Microsoft, I do whine. Because it pushes me to cross the boundary again. I was just getting comfortable with Asp.net Web API2, there comes a landslide of stuff falling on my head to start looking into Node, microservices and completely out of Microsoft. It's just a pain for me to set up a new environment and start learning things and deal with teams to do it. If there's a way to achieve the same objective with Microsoft, that's awesome, I'd first try it out. :) thanks for the reply.

Yup, "kestrel" might be a right fit for the comparison. Just looking at this after Pete pointed out a while ago. Alright, Now I got the next pile of things to break-head & learn. Kestrel, OWIN, Katana, whatnotana :doh: PS: I was thinking OWIN to be yet another services like OAuth., until I read the article I just posted above loll :-O

Node - just because it's Javascript. You want to call this just a "run-time"? :) My only question was, Why MS could not think of dedicated, light weight offering, that can completely open up the world for micro-services pattern. (Don't say micro-services has been there before they are called so). Every technology has been there in every era but on a dim light, many times not even seeing the light of day, not doing anything significant. Mainly not reaching to the public usability. Micro-services, mainly after Node took over, YES, it's changing the landscape of a Web-server "module" & distributed computing. When Microsoft had all the technology and equipped with good server experience, they should have thought about a Node like "Run-time" or Light-weight Server "Module" - (Whatever you wish to call).

Microservices and SoA pre-date Node by quite a bit. What Node does is lower the barrier to entry, but that does not make it more performant nor does it represent a shift in the zeitgeist.

It's not new, it's been around a long time, and IIS has been leveraging it for well over a decade. You're also confusing a runtime with a software module, which makes me wonder how anyone on this site (outside of QA) can be so uniformed about basic computer operation. The reason Node needs to advertise this capability is that JavaScript does not normally support non-blocking IO. That's because JavaScript was never intended to do the things that Node allow it to. Please think about that for maybe a minute before your uninformed, tiresome, and inevitable anti-MS response.

Perhaps because some of us actually understand how complex the industry has actually gotten. Someone that has worked in nodejs for years focusing on human factors engineering is unlikely to need to know in detail that nodejs actually does use threads much less how it does that. But I suspect that those that are creating the next version should have a strong knowledge of that but that doesn't mean that they do. I worked in an office with probably 20 developers and I was the only one that understood bit manipulation. There was one other person that recognized what I was doing but could not explain what I was doing. That didn't make them stupid people it just meant that they had different areas of expertise than what I did. I worked in one group and being young and inexperienced I was dismissive of another developers programming skills. But once every three months that person, and only that person, would go before a board of people I had never even met to justify what our group did. And every month they allowed us to continue. And the result, which I only learned latter, of failing to do that would be that the group would be disbanded and the members of the group would be required to find another position in the company within two weeks or they would be let go. Now who was really more important to my actual job, me who I thought I could program or the guy that made sure I actually had a job that I could program at?

In all the docs, it's said that Node makes use of non-blocking I/O. I guess this is not something totally new. All high-performance servers have been using the same. Even on OS level or network level. What's making Node.js claim this "non-blocking" tag so much? I was thinking Apache/IIS or any servers meant for high-volume connections, should be using non-blocking I/O. (i.e I/O port completion model for IIS on Windows). I still believe IIS should be using IOCP internally, but may be only to a limited extent? as the documents say traditional Servers (Apache/IIS) does create 1-to-1 thread for each client. It's a bit puzzling, why Microsoft did not think about a Node like pure-Single-threaded solution for servers. Summary of questions: 1. IIS is really a dumb, 1-to-1 thread spawning server for every connected client? 2. Why Microsoft couldnt think of a Node model for web server, when I/O port completion has been so widely used in so many enterprise level network, I/O frameworks?

Perhaps merely marketing or to make those doing it feel special. But one unintentional (or perhaps intentional - I don't know) is that it emphasizes that you need to insure that your own code isn't written in a way that blocks. Because you can write code that basically blocks everything. So maybe it just acts as a reminder to make sure people figure out the correct way to do it.

Even if so that isn't generally a concern. Everyone likes to think they are writing the next facebook but most are not. And at the point where a company gets big enough that connection concerns are a problem they, probably have so many other architecture problems already that it becomes a non-issue.

Why do we think low of a "run-time" ? I truly don't get this. Just because a 'language' is interpreted, you want to look down on it? Or just because it's ending with ".js" (This is just for you to laugh :D) Okay, so my view - I really don't care if a language is interpreted, compiled, or HOT-interpreted, JIT, and there are even more of them with lots of combinations. Does it really matter? The problem is, you are focusing on the "js" part of Node. I'm looking at the "npm" part of it. You should definitely try giving a look at it. It's a truly evolved world sorting out so many problems. In that aspect, I would say, Node & it's eco system is much more bigger than your "big software module - IIS". Please note - I'm not saying IIS should have package manager. IIS might be good at what it's doing. My point here is , Node is not just a simple 'run-time' like the JS on browser. Node seems to combine programming, Package Management + Serving all under the same box. So I feel it definitely deserves a better treatment.

Exactly, I was truly puzzled how can you "always" ensure non-blocking code. (edited* - supposed to mean CPU bound tasks. Not I/O bound) But even with this limitation, How Node.js managed to steal such a huge spot-light? If there's real substance to it, then I would really feel, Microsoft should have done it first , with all the expertise they already have in their hand. Instead of doing a follow-up product. I've seen Microsoft do this a lot of times. A particular trend gets popular, and they introduce their version of it. You'd call this Innovation? Windows Phone was a typical example. In recent days, we can really see they are getting closer to being cool :) The strength I see at the moment with Node is their NPM, but this is all evolved after the initial hype. And Microservices architecture really had a good take-off with Node.js. The basic nature of Node solution architecture feels micro. Before Node arrived, "Server" development was an epic. People talk about J2E, .Net N-tier server arch. It did feel like you have a decent learning curve to start doing something on the server. & Deployment , config on the IIS , had it's own learning curve. Honestly, I feel Node + NoSQL feel bare-bones stuff & anybody can just jump in and start doing things even for a decent requirement, it works. And you'd pay just for the hosting. That's the reason Node became Startups favorite.

You know, there's always a fear to talk about things. Because people put you down instantly. This whole thread, I've been saying I'm learning things.
