JVM+PG+k8s is absolutely not "boring tech" to me. LAMP, this is boring tech. You can switch Apache for Nginx, and MySQL for another SQL database, but that's the idea. People still develop in PHP today, and performance-wise, assuming you follow standard good development practices, and good servers, it can take a lot. If it was good enough to get Facebook started, it is most likely good enough for you, and the situation has much improved since the early days of Facebook, a lot of it thanks to Facebook itself, and also better hardware. PHP security is not as terrible as it once was too. At work we have a couple of Spring projects, and I don't think I have hated a tech stack more than that. If you to illustrate the "action at a distance" anti-pattern, look no further. I'm sure most Spring web apps could be implement in PHP for a fraction of the size, both in terms of application code and memory. I don't do k8s, so I have no real opinion except that it looks like overkill in many cases. As for Postgres, nothing against it, it is a very good SQL database, though my opinion is that you should limit yourself to basic SQL as much as you can, so that you are not dependent on a particular database.
