First of all, such changes have affected an entry point of a distributed system, called gateways. For a long time, the only Spring module that made it possible to run an application as a gateway was the Spring Cloud Netflix Zuul module. As we may know, Netflix Zuul is based on a Servlet API that uses blocking synchronous request routing. The only way to paralyze the process's requests and obtain better performance is through tuning the underlying server thread pool. Unfortunately, such a model does not scale as well as the reactive approach, and the ...
