> You're saving on 2-3 days upfront on racking and cabling, on boxes that will last at least 3 years, probably longer. "Infrastructure" is a little broader than just some cabling, much broader. You're also assuming that whoever will be in charge of DIY is a) more competent at scale than whatever will be scraped together for the cloud, and b) available with no resource cannibalisation. The point the person you're replying to was trying to make was that for every "good" hire you're deciding where to allocate them, and sourcing plumbing from a cloud provider lets you allocate preferentially to product development (ie business growth). Even if you "pay more" for that setup, in theory business growth you will achieve more rapidly pays for it many times over (first mover advantage, market leader advantage, cost of money over time, etc). The costs of pinching the wrong penny and making technical hiring more difficult, diluting your talent pool, can be the difference between huge success and too little too late. An undermanaged local setup that cost you 3 years on Time to Market will bite you long before 'eventually' comes, and you won't have oodles of cash to fix the problem.
