#HAPROXY LOAD BALANCING HOW TO#

In this tutorial, we will go through the process of configuring a HAProxy-based load balancer for HTTP web servers. What are we going to achieve in this tutorial? Its features include automatic health checks, customizable load balancing algorithms, HTTPS/SSL support, session rate limiting, etc. Designed in a single-threaded event-driven architecture, HAproxy is capable of handling 10G NIC line rate easily, and is being extensively used in many production environments. HAProxy is a popular open-source load balancer and proxy for TCP/HTTP servers on GNU/Linux platforms. It will prove itself useful in the future when you need to scale your environment. Or if you are just planning your architecture for a bigger project, itвЂ™s a good habit to plan usage of load balancer upfront. Where and when to use load balancing?ДЄs load balancers improve server utilization and maximize availability, you should use it whenever your servers start to be under high loads. It also allows you to easily scale in/out an application deployment by adding or removing extra application servers with changing workloads. By balancing application requests across multiple available servers, a load balancer prevents any application server from becoming a single point of failure, thus improving overall application availability and responsiveness. HTTP load balancing is a networking solution responsible for distributing incoming HTTP or HTTPS traffic among servers hosting the same application content.

And today I will show you how to set up HTTP load balancer using HAProxy. But how can we eliminate these downsides? In most cases a proper load balancing solution will do the job. Unpredictability or inconsistent performance is not something you can afford. Even modern devops and continuous delivery practices can threaten the reliability and consistent performance of your web service. When faced with unexpected traffic spikes, organic traffic growth, or internal challenges such as hardware failures and urgent maintenance, your web application must remain available, no matter what. Increased demand on web based applications and services are putting more and more weight on the shoulders of IT administrators.
