HAProxy (High Availability Proxy) is an open source software that serves as a load balancer and proxy server for TCP and HTTP-based applications. It is used to improve performance and reliability of server environments by distributing loads across multiple servers (Web, applications, databases, etc.).

It supports highly complex infrastructures and is the preferred solution for several popular websites with heavy traffic.

With unlimited capabilities, it can serve data centers with hundreds of thousands of simultaneous users (online stores, banks, etc.) and handle millions of requests per second.


HAProxy has many built-in security features to protect applications from malware, bots, attacks on HTTP, SSL, DoS, etc., as well as a WAF (Web Application Firewall).

Especially in dynamic microservices environments that have now become the norm for modern applications, the challenges that need to be addressed are unique. What is needed now is an effective, yet highly efficient, application delivery controller. HAProxy is the predominant application delivery solution for some of the world's largest and most complex microservices architectures. Its clientele features some of the most powerful brands worldwide, such as Booking, Netflix, Twitter etc.

In short, when an application delivery controller solution is required, HAProxy is the best option.

In addition, HAProxy is the optimal automation solution for a disaster recovery plan. On several occasions, manual traffic switching from one data center to another requires hours or even days, which is unacceptable for infrastructures with heavy traffic and highly sensitive data (e.g., banks). HAProxy can automatically direct the workload, thus eliminating downtime.
