To get started, spin up a new CentOS 8 server or instance and bring the system up to date: sudo yum update -y It will even send all traffic that comes to a predefined URL (like /api/) to a different server or pool of servers.

In this article, I will walk through setting up a very basic HAProxy installation to use HTTPS to listen on secure port 443 and utilize a couple of backend web servers. For example, you might want to handle your static content with a couple of cache servers, such as Varnish, but route anything that requires dynamic content, such as an API endpoint, to a more powerful machine. You can also route requests to different servers depending on the context.

With HAProxy, you can add more servers to the backend pool when you need them and remove them when you don't. Maybe you want to add some redundancy in case one server fails. Perhaps your existing web server isn't robust enough to meet peak demand during busy times of the year and you'd like to add another, but only temporarily. The ability to distribute load means you don't need to purchase a massive web server with zillions of gigs of RAM just because your website gets more traffic than Google.Ī load balancer also gives you flexibility. In fact, HAProxy can balance any type of Transmission Control Protocol ( TCP) traffic, including RDP, FTP, WebSockets, or database connections. Why would you need a load balancer?Ī load balancer is a way to easily distribute connections across several web or application servers.

Learning the basic skills and concepts covered in this tutorial will help you use HAProxy to build a more robust, far more powerful infrastructure. HAProxy is known as 'the world's fastest and most widely used software load balancer.' It packs in many features that can make your applications more secure and reliable, including built-in rate limiting, anomaly detection, connection queuing, health checks, and detailed logs and metrics. Whatever your situation, you can benefit from using the HAProxy load balancer to manage your traffic. Perhaps you're the server administrator for a small business maybe you do work for a huge company. You might be a hobbyist, self-hosting a website from a couple of Raspberry Pi computers. You don't have to work at a huge company to justify using a load balancer.
