> My app with a couple of hundred thousand users per year? per month? per day? simultaneously? doing what? it matters. i ask this as someone who runs a $40/mo Linode with a debian/nginx/node/mysql stack that's definitely 20x over-provisioned for an e-commerce site with 10k daily visitors, 15 simultaneous backend users (reporting, order-entry, CRM, analytics) and 0 caching tricks. i could easily run the site on any 5 year old laptop with an SSD and 8GB RAM. normalize/de-normalize when needed, understand and hand-write efficient SQL queries (ditch ORMs), choose small/fast libs carefully (or write your own), and you can easily serve 100k users per day on a single cheap VPS with no orchestration/replication/hz-scaling bullshit. definitely can't say the same about 200k simultaneous users - that would need proper hardware, but can still be a single server.
