There is a law of diminished returns at some point in scaling websites. A while ago Reddit hit a scale where a move to Amazon's services seemed like the right thing to do. At that time the argument was solid. Since then the site has outgrown Amazon's services at Reddit's price points. Spinning up new services has an extremely low ROI. The preverbial wheel of scalling solutions needs to be re-invented, yet again. Not all services are created equal so no one is truly re-inventing anything, just applying unique solutions to unique problems. That takes manpower. Heck just to move from Amazon to a dedicated will take a team larger than they had a month ago. That's right from the horses mouth. Don't have the energy to fish out the link, though.
