DevOps & Delivery Technologies
HAProxy
HAProxy is a high-performance, open-source load balancer and reverse proxy designed for high availability and scalability. It efficiently distributes traffic across servers to improve reliability, performance, and fault tolerance.
What is it?
HAProxy is an open-source load balancer and proxy server that operates at both Layer 4 (TCP) and Layer 7 (HTTP). It is widely used to ensure high availability and optimal traffic distribution in modern infrastructures.
What does it do?
HAProxy routes incoming traffic to multiple backend servers, performs health checks, manages failover, and optimizes request handling. It supports SSL termination, rate limiting, access control, and advanced routing rules.
Where is it used?
HAProxy is commonly used in SaaS platforms, high-traffic websites, APIs, microservices architectures, containerized environments, and enterprise infrastructures requiring reliable load balancing.
When & why it emerged
HAProxy was first released in the early 2000s to address performance and reliability challenges in web traffic management. It emerged as a lightweight, efficient alternative to hardware load balancers.
Why we use it at Internative
We use HAProxy to design resilient, high-availability architectures. Its performance, flexibility, and stability make it ideal for load balancing APIs, web applications, and distributed backend systems.
