Well, I missed the cloud boat, so it's no wonder I can't be employed in this market.
Take a project you've done and start figuring out what it would take to do it at 100x the traffic. Now figure out what it would take to make each of the instances stateless. Lastly, how can you make it work through network partitions, latency, and eventual consistency?
These are real problems people in the "cloud" are working with. Just being able to talk about these types of problems excitedly says a lot about where an engineer fits.
