The Quest for ASP.NET Scalability

The Quest for ASP.NET Scalability 05/31/2004 11:39 PM
At the height of the dot-com boom in the mid-1990's, many companies burst onto the scene as Application Services Providers (ASPs) hoping to capitalize on the wave of Internet success stories, and rake in some loot. Aside from the unfortunate market collapse that followed, ASPs had other issues to deal with such as training staff to effectively build and manage a secure, reliable and highly available operation. Today, Web-enabling architecture is prevalent, particularly since Web services have become a staple for most applications, and the growing pains of ASPs past are feeding businesses everywhere with a hunger for successful implementations for 24x7 applications. As Service-Oriented Architectures (SOA) themes spread across organizations, applications are now reaching wider audiences than ever before. Gone are the days where you can sling some code, ship product, and cross your fingers.

Webl0g scalability

Webl0g scalability 03/12/2003 11:33 AM

Chris Anderson How many people should I expect to host on a 512MB machine?

Mark Pilgrim's and my blogs are hosted on the same machine, and combined get a fair amount of traffic.  This currently is a 1Ghz AMD Duron processor w/512MB.

CPU and memory usage was not a problem even when my blog was dynamically generated via CGI for every request.

I'm very curious about your XML formats both for interchange and persistence.  Is this documented somewhere?

The scalability myth

The scalability myth 08/19/2004 12:45 AM

At one time or another, nearly every kind of information technology has been judged and found wanting. The failures are often summed up in that most damning of epithets: "It doesn't scale." The reason, of course, is that at one time or another, for one reason or another, every kind of information technology has failed to scale.

Unfortunately for the victims tarred with that brush, scalability is a wildly imprecise term. Applications may be expected to scale up to massive server farms or scale down to handsets. And size is only one axis of scalability. Others include bandwidth, transactional intensity, service availability, transitivity of trust, query performance, and the human comprehensibility of source code or end-user information display.

...

It's tempting to conclude that the decentralized, loosely coupled Web architecture is intrinsically scalable. Not so. We've simply learned -- and are still learning -- how to mix those ingredients properly. Formats and protocols that people can read and write enhance scalability along the human axis. Caching and load-balancing techniques help us with bandwidth and availability. But some kinds of problems will always require a different mix of ingredients. Microsoft has consolidated its internal business applications, for example, onto a single instance of SAP. In this case, the successful architecture is centralized and tightly coupled.

For any technology, the statement "X doesn't scale" is a myth. The reality is that there are ways X can be made to scale and ways to screw up trying. Understanding the possibilities and avoiding the pitfalls requires experience that doesn't (yet) come in a box. [Full story at InfoWorld.com]

Based on the reaction so far, it seems like this piece went over well. It's so nice to be able to track reactions that way. ...

PHP Scalability Critique

PHP Scalability Critique 07/17/2004 04:11 PM

Experiences of Using PHP in Large Websites: This is a well-written, well-researched, but ultimately damning indictment of PHP's use in "large Web sites."

The conclusion arrived at is that, in some circumstances at least, PHP's tendency to create more problems than it solves makes it an inappropriate choice. However, we also recognise that there are some situations in which PHP is to be used.

I agree with a lot of what's written here, but they're not roadblocks that have ever really hindered me. If you abstract your code well, and you're not working on a site with a lot of other people (I usually work alone), most of these problems are non-events.

Yes, function naming is goofy. Yes, there are no namespaces. Yes, the whole magic quotes concept is a pain. But I still write better stuff faster with PHP than with any other langauge.

They talk about templating and code separation early on, and the perfectly describe what has become my de facto templating method:

Divide every PHP page up into two parts: the former performs database queries and does whatever else is needed to calculate the content for the page, before storing the calculated content into a series of variables which — and this is crucial — contain no markup. Then the latter part of the page can simply embed variable values into HTML markup, using loops where appropriate to traverse potentially-complex data structures containing the actual content.

I actually have two files — the actual code, then a ".tpl" file that's included at the bottom of the code. That way, two vastly different sets of code can use the same template. I know this isn't perfect, and Joe never hesitates to tell me that I should be using Smarty instead, but it works well for me without the (1) need to learn another language syntax, and (2) the additional overhead required for template processing.

Thank to Jo nathon Hollin for this link.

Syndication Scalability Problem

Syndication Scalability Problem 09/08/2004 07:44 PM

Scoble writes:

RSS is broken, is what happened. It's not scalable when 10s of thousands of people start subscribing to thousands of separate RSS feeds and start pulling down those feeds every few minutes (default aggregator behavior is to pull down a feed every hour).

Bandwidth usage was growing faster than MSDN's ability to pay for, or keep up with, the bandwidth. Terrabytes of bandwidth were being used up by RSS.

So, they are trying to attack the problem by making the feeds lighter weight. I don't like the solution (I've unsubscribed from almost all weblogs.asp.net feeds because they no longer provide full text) but I understand the issues.

I know of a major broadcaster that refuses to turn on RSS feeds because of this issue too. We need smarter aggregators and better defaults.

I think it's high time we addressed this problem and I think the upcoming BloggerCon is the right place to do it.

We need to 'teach' syndication clients to speak with servers and other clients at more intelligent level than that of a spoiled child screaming GIVE ME GIVE ME endlessly.  We need more than just technical solutions.  We need to introduce ways to reward clients that improves scalability and punish bad clients that hog resources selfishly.

Toilet Paper Scalability

Toilet Paper Scalability 03/14/2005 06:06 PM

Here's a fun example of why scalability is hard: What problems do you run into by going parallel on your toilet paper dispenser?

Although most homes have only single roll holders, most commercial establishments have long ago switched to devices that hold multiple rolls. We decided to install one, so we purchased holder of two rolls, side by side.

We discovered that although we now had two rolls instead of one, the problem was not solved. Both rolls ran out at the same time. Sure, it took twice as long before the rolls emptied, but we were still stuck with the same problem: no more paper. We had discovered that the switch to two rolls meant we had to use more sophisticated behavior: the algorithm for tearing of paper mattered.

A fun article with a good look into how computer nerds look at the world, but it also hints at actual issues with scalability: More does not automatically equal better.

High Performance PHP: Scalability

High Performance PHP: Scalability 07/02/2004 06:35 AM

We need barking dogs to fix "The PHP
Scalability Myth"

We need barking dogs to fix "The PHP
Scalability Myth" 10/29/2003 12:11 AM
This above link is a great article, but you must be an asphyxiating ostrich burrowed in the sand to say that PHP doesn't scale. It's not that slow a programming language, it has few bottlenecks, and perhaps most important - there are many case studies of large web sites using it for mission critical work (eg. Lufthansa's online booking and Yaho o).

However I do feel something is still missing from PHP. Not in the language per se, but in the conceptual overview. What we really need are dogs barking and cats meowing in our very own virtual Pet Shop. For people who don't understand this reference, the Pet Shop is famous web application created to demonstrate best practices in scalability and software design for J2EE and .NET.

In contrast, there is no reference PHP Pet Shop, and no accepted and well-documented methodology on how to create scalable web-sites with PHP. So you need to be very smart, or get the advice of technical gurus to keep everything scalable and running smoothly. It's no accident that Yahoo, perhaps the biggest web-site that has invested heavily in PHP, employs so many cool cats who have a deep knowledge of PHP such as Rasmus and Andrei.

Update: Slashdot discusses this article. I liked this comment best:

The sad reality is that so few developers know enough to fully exploit J2EE that they wind up doing little more than what PHP does better in the first place.

True wisdom is knowing your limitations (18 Oct 2003).
