Hello everyone, I have a question about scalability of Java applications. Recently, I encountered an interesting case: we were developing a platform for processing large amounts of data, but at some point the server began to barely handle requests. It turned out that one of our microservice architectures was not sufficiently optimized for the load. We had to rebuild some of the logic. I'd like to hear how you solve similar problems. What approaches or tools do you use to keep the system stable as users grow?
