The simplest way is to just do it.

You are fortunate that you live in the age of cloud computing. For instance, you can spend $10 for a day and get access to more compute resources than most people could hope for after months of budget proposals.

Find a problem, solve it, launch it, test it, find bottleneck, kill it. Repeat this enough times and you can start to a feel for where bottlenecks will happen and how fail happens.

I second this.

I wrote a distributed crawler from scratch with 10 EC2 machines. It was one of the best learning experiences ever!
