I had to scale a high profile Wordpress site during the pandemic. It got huge spikes daily during a press conference. It got 150k hits per second. Apart from moving it from windows to Linux, I put it in front of varnish and spent a few hours tweaking the config to make sure everything still worked. It was my first time using varnish so it took longer. It performed flawlessly for years. Varnish was a real workhorse.

Indeed, that's one of the most popular cases and I even used it myself couple of times. Though when frontend devs cannot explain which CORS headers and for which origins they do need (again, I'm sysasmin, not even daily reader of Mozilla Developer Network), chances for server/infra level like Varnish to be mentioned is close to 0. With higher chances k8s cluster introduction to be mentioned.
