All kinds of companies lose millions of dollars of revenue per day if not hour if their sites are not stable.... apple, amazon, google, Shopify, uber, etc etc.
Those companies have decided the extra complexity is worth the reliability.
Even if you're operating a tech company that doesn't need to have that kind of uptime, your developers probably need those services to be productive, and you don't want them just sitting there either.
