ingress-nginx is not the same as nginx ingress

After two weeks of reading documents, I finally realized that Ingress-Nginx and Nginx Ingress are not the same thing; they differ in functionality as well as implementation. There are even documents guiding the migration.

• Migrating from the Ingress-NGINX Controller to the NGINX Ingress Controller
• NGINX Ingress Controller
• Ingress-NGINX

Ingress-NGINX is the community edition with more participants and a greater number of search results. NGINX Ingress is the commercial edition, richer in features but with lower community participation.

According to Deploy with NGINX Ingress Controller - Overview

NGINX Ingress Controller can be used for free with NGINX Open Source. Paying customers have access to NGINX Ingress Controller with NGINX Plus. To deploy NGINX Ingress Controller with NGINX Service Mesh, you must use either:

Additionally, the Nginx commercial edition’s official website has moved to www.f5.com
