Orchestration became the answer before anyone asked what the question was. There are two ways to scale, and the order matters. Vertical is handling more inside a single instance. Horizontal is adding instances behind a load balancer. Most teams skip straight to horizontal. But if you don't know the ceiling of one instance, you're not scaling. You're guessing, and you're paying for that guess every month. Here's what changes when you do the work: you learn that after rigorous optimization, one instance of size X handles 1,000 concurrent requests at $100/month. Now you have a base cost. Peak traffic becomes a number you can predict instead of a bill you explain after the fact. Your infra spend turns into a line item finance can actually plan around. With that knowledge, if marketing wants to bring 3x more traffic to the ...
