How to Install/Setup Nginx Load Balancer on Azure (Load Balancer for Web Servers & Applications)

Install and Setup Nginx Load Balancer on Azure. Nginx is open source software for web serving, reverse proxying, caching, load balancing, media streaming, and more. NGINX is a highly scalable Load Balancer, meaning that its service grows along with its clients traffic. Load balancer for web servers, applications and all types of resources in Azure.

Load Balancer Methods
The following load balancing mechanisms are supported in Nginx:

Round-robin — Requests to the application servers are distributed in a round-robin fashion.

Least-connected — Next request is assigned to the server with the least number of active connections.

IP-hash — A hash-function is used to determine what server should be selected for the next request (based on the client’s IP address).

Session persistence – With ip-hash, the client’s IP address is used as a hashing key to determine what server in a server group should be selected for the client’s requests. This method ensures that the requests from the same client will always be directed to the same server.

Weighted load balancing – It is also possible to influence Nginx load balancing algorithms even further by using server weights

Reverse proxy implementation in Nginx includes load balancing for HTTP, HTTPS, FastCGI, uwsgi, SCGI, memcached, and gRPC

Load balancing with in-band health checks
NGINX can continually test your HTTP upstream servers, avoid the servers that have failed, and gracefully add the recovered servers into the load‑balanced group. Reverse proxy implementation in Nginx includes in-band (or passive) server health checks. If the response from a particular server fails with an error, Nginx will mark this server as failed, and will try to avoid selecting this server for subsequent inbound requests for a while.

Health check a URI
