That you <i>can</i> run Twitter with a much smaller crew is probably true, but also kind of irrelevant. Question is, can you make it so overnight.<p>You write stuff totally differently depending on whether it's going to be maintained by just you, or a team of 50 DevOps etc. Yes you could probably run stuff on N servers instead of M where N << M, thus requiring much fewer sysadmin support etc but that requires that you <i>designed</i> things that way from the get go.<p>But how much work is it to realign stuff to run this way? Probably initially more work than just keeping it going as is.<p>It's like, you can't take a ICE car and turn it electric by just cutting out the engine and sticking a battery where the fuel tank was.
