Excellent post . i'm building a node app which is completely stateless and uses JWT for authentication. i'm planning to host the app on 10 servers each having only i cpu CORE (as it is stateless there is no need to bother about session sync) each server has nginx to frontload node app on that particular server . and all these servers will be front loaded by 1 load balancer . so my question is in my scenario do i really require cluster module ?

You should make a benchmark with one server and see if you get performance improvements by using a cluster with 1,2,3,... processes. As a rule of the thumb, the optimum lies by ca. `<number of CPU cores> + 1` processes

As far as I understood, even having only 1 CPU core, the cluster stills brings to you the benefit of having no downtime when reloading the application on a specific server. Yeah, I know... you already have other 9 servers to take care when 1 server is restarting the app... It may be a "micro-benefit", but it is still a benefit. (Specially if you start with one server alone before adding the others.)
