Intro to NGINX

What is NGINX?

NGINX is a free, open-source, high-performance web server with a rich feature set, simple configuration, and low resource consumption that can also function as a reverse proxy, load balancer, mail proxy, HTTP cache, and many other things.

How NGINX is working?

NGINX allows you to hide a server application's complexity from a front-end application. It uses an event-driven, asynchronous approach to create a new process for each web request, with requests handled in a single thread.

Using NGINX with FLOWX Designer

The NGINX Ingress Controller for Kubernetes - ingress-nginx is an ingress controller for Kubernetes using NGINX as a reverse proxy and load balancer.

Ingress allows you to route requests to services based on the host or path of the request, centralizing a number of services into a single entry point.

The ingress resourcesimplifies the configuration of SSL/TLS termination, HTTP load-balancing, and layer routing.

Integrating with FLOWX.AI Designer

FLOWX.AI Designer is using NGINX ingress controller for the following actions:

1. For routing calls to plugins
2. For routing calls to the FLOWX.AI Engine:

• Viewing current instances of processes running in the FLOWX.AI engine
• Testing process definition engine backend
• Accessing REST API of the backend microservice

3. For configuring the Single Page Application (SPA) - FLOWX.AI Designer SPA will use the backend service to manage the platform via REST calls

In the following section, you can find a suggested NGINX setup, the one used by FLOWX.AI:
