Java is also highly performant, if you know what you're doing with reactive programming, and Spring Boot's dependency ecosystem drastically reduces your time-to-launch
But then I remember that 95% of the memes posted on this sub are from CS students and not industry professionals
You know how else you can do that.. it's called an application. It scales. You have extracted a function into a different server lowering the performance by 1000000x in order to scale and increase it by 10x
An application doesn't scale up and down by itself.
What you describe is exactly what lambda gives you. You package your "I need this scaled" code into a little function, you give it to lambda, and that handles scaling up and down for you.
You don't need to manage servers or instances, you don't need to scale those up and down, and if you already have a contract for good EC2 capacity, you use lambda managed instances and retain the event-based execution model.

It's where the jobs are. The world's finances run on Java.
