> Stability and Scalability are properties of architectures
But the architecture starts at the virtual machine level. Without a decent VM you'll have to put more effort into building a scalable architecture.
True story: the team working on Photoshop Express tried Rails for displaying a 404 Not Found page (containing some dynamic content). Because the interface was already in tests by a lot of people, they couldn't even display a static rhtml template ... Mongrel was segfaulting because of the high loads. Now, this may be an incident that got fixed since then (last Summer), I wouldn't know since I'm not working with Rails ... but it surely sends shivers down my spine.
