We probably need to collectively start doing the same thing that people do when they ask "How can I speed up my code?"... "Profile, profile, profile."

"How can I make my code cloud-scale?" "Profile, profile, profile." First make it fast. Not hyper-ultra fast, optimized to within an inch of its life with embedded ASM and crazy data structures, but as far as you can get it while still writing simple, sensible code. Then, only if you have a problem do you even worry about whether it should go cloud-scale, and by the time you're done with this you'll probably already have a good idea how to partition the problem better because you learned a lot more about it while profiling.
