The app can be running on many servers distributing the load. Once that is achieved, it's literally trivial (a few button clicks) to add/remove servers, or have AWS do it automatically with auto-scaling. Like maybe the bulk of your load is during US business hours. You could have 4 (or whatever) app servers running during those times, and only have 1 or 2 during off peak times.This setup also helps with failover, as there isn't a single point of failure if you set it up right. If an app server goes down, the other servers just pick up the load. You destroy the bad server and bring up a new one with no downtime to your app. That can also be automated.This type of setup is different from a typical setup. You'd have a separate db server that the other webservers share. You'd use S3 for storing all assets instead of on an individual server, so that all servers (acting as one) has access to the same data. If user A uploads a file to Server A, it needs to be accessible by servers B, C and D as well, so it can't be stored on the individual webserver.The same goes for sessions. A user might login to server A, but the next request gets served from server B. So you need a common session store that all servers use, like redis.Now you're just left with dumb webworkers, so you can just add new ones to increase capacity and scale.Here's a good place to start learning: <a href="https://serversforhackers.com/c/so-you-got-yourself-a-loadbalancer" target="_blank">https://serversforhackers.com/c/so-you-got-yourself-a-loadbalancer</a></blockquote>
