Reverse Proxy(Haproxy) with Ansible

Setting up Reverse Proxy and Load Balance with Haproxy using Ansible.

A reverse proxy is a server that sits in front of web servers and forwards client (e.g. web browser) requests to web servers.

A reverse proxy operates by:

• Receiving a user connection request
• Completing a TCP three-way handshake, terminating the initial connection
• Connecting with the origin server and forwarding the original request

Some of the benefits of a reverse proxy :

• Load Balancing : A popular website that gets millions of users every day may not be able to handle all of its incoming site traffic with a single origin server. Instead, the site can be distributed among a pool of different servers, all handling requests for the same site. In this case, a reverse proxy can provide a load balancing solution which will distribute the incoming traffic evenly among the different servers to prevent any single server from becoming overloaded.
• Protection from attacks : With a reverse proxy in place, a web site or service never needs to reveal the IP address of their origin server(s). This makes it much harder for attackers to leverage a targeted attack against them. read more
