That's currently my full stack.
I don't use Tomcat and Jetty anymore, just build standalone jars and depending on the company, pop them into a docker container.
Yes i've already read your article, he is very interesting ! (i've start to read things about vertx and kotlin thank's to your post)
You don't get performance or other issues with your stack ?
It's good for everything (ex : Rest API ... ?)
System I just completed using this stack is doing fine under moderate load. Will be load testing it over the next 3 months to see how far I can push it until it starts falling apart and making incremental improvements as I test things.
