Most of my products lately are some backend servers that respond to remote requests from SPAs or various sister backends. All servers are written in modern C++ and each one is a single executable. The performance is stellar. Modern C++ along with some libraries helps to keep application specific code small - about the same size as if written in more "traditional" web languages.
