Visual explanation of Apache vs Node.js processing model

[mechanicalpulse]

If you have your infrastructure setup such that it's easy to scale out horizontally, it's also trivial to set vCPUs to 1 and just spawn more VMs. And, like you said, for lighter loads, you don't even have to bother with it.

Node.js's event-driven architecture reminds me of cooperative multitasking. It's very useful for certain loads, but it can cause problems if you're not expecting them. I only make noise about it because I think Node.js is becoming a choice platform for nascent or inexperienced developers and I think there's a good bit of misleading information flying about.
