I've been dabbling in code for many years now but it's always been personal projects. I don't have experience with much traffic. I was recently reading through a "Hello, World." tutorial for Dropwizard and at the bottom it states "Well, congratulations. You’ve got a Hello World application ready for production (except for the lack of tests) that’s capable of doing 30,000-50,000 requests per second."
Although what I can only imagine as being a good problem to have, what do you have to start doing at that point? If my application was built upon Dropwizard, would I have to start migrating to something different, or is that where deploying to multiple "nodes" and load balancing comes in?
