Is Spring still the king? Current state of modern JVM backend frameworks

Technology landscape is ever-changing. Status quo is not an option in modern IT. This forces us to be constantly up-to-date with available solutions. Nowadays, comparing competing backend frameworks we need to take into consideration plethora of various aspects. What is more, major differences between currently available solutions are not always crystal clear at first glance. During this talk, we are going to verify whether popular and widely adopted solutions still keep up with newcomers, how to choose the right tool for the job and how to avoid “shinny thing” fallacy.
