Nginx in deployment of Java full stack application on AWS (ALB, EKS)

Question

In Java+Angular full stack application that is deployed on AWS using EKS and exposed to outside using ALB: Does Nginx sit in between 1)ALB,Angular or 2)Angular front end,Java spring boot backend or 3)is Nginx redundant?

Reviewed articles on medium but I am not sure where does Nginx exactly sit in Java full stack application in AWS that is also using ALB!(load balancer)

• OctavianM: ALB or not, you need some kind of server that serves the static assets needed in order to render the angular app. This means the index.html, javascript files and css files. That's what nginx does for you. It is redundant in the sense that you could most likely perform static file serving using the same server you use for the backend API.
