Look at almost all successful companies and they're pretty "boring" under the hood: GitHub and Stripe are Ruby on Rails, Facebook is PHP, Google is Java (still almost all new code written in 2020)... it gets the job done. Yes, they do some optimizations (HHVM etc.), but nobody is considering rewriting FB, Stripe or Google services in the language du jour.
The complexity of the infra and deployments are always relative to the size of the company, and no two companies are alike there. Small or big, it's all bespoke. Even if a few pieces are shared as open source projects, there's a veritable iceberg of complexity in the form of inhouse knowledge and tooling in each of the companies, there is nothing even close to a standard deployment system in either green field startups or FAANGs today.
