HAProxy Traffic Mirroring for Real-world Testing
Nick RamirezTraffic mirroring makes it possible to stream production traffic to a test or staging environment. Use the HAProxy Traffic Shadowing agent to enable mirroring. The HAProxy Stream Processing Offload Engine (SPOE) lets you stream data to an external agent in real time...
HAProxy Layer 7 Retries and Chaos Engineering
Nick RamirezHAProxy 2.0 introduced layer 7 retries, which provides resilience against unreachable nodes, network latency, slow servers, and HTTP errors. HAProxy powers the uptime of organizations with even the largest traffic demands by giving them the flexibility and confidence...

Test Driving “Power of Two Random Choices” Load Balancing
Willy TarreauThe Power of Two Random Choices load-balancing algorithm has piqued some curiosity. In this blog post, we see how it stacks up against other modern-day algorithms available in HAProxy. Recently, I was asked twice about my opinion on supporting an algorithm known as...
HAProxy 1.9.2 Adds gRPC Support
Nick RamirezHAProxy provides end-to-end proxying of HTTP/2 traffic. Use HAProxy to route, secure, and observe gRPC traffic over HTTP/2. Read on to learn more. HAProxy 1.9 introduced the Native HTTP Representation (HTX). Not only does this allow you to use HTTP/2 end-to-end, it...
Serving ECC and RSA Certificates on Same IP with HAProxy
Nenad MerdanovicECC and RSA certificates and HTTPS To keep this practical, we will not go into theory of ECC or RSA certificates. Let's just mention that ECC certificates can provide as much security as RSA with much lower key size, meaning much lower computation requirements on the...
HAProxy’s Load-Balancing Algorithm for Static Content Delivery with Varnish
Baptiste AssmannHAProxy's load-balancing algorithms HAProxy supports many load-balancing algorithms which may be used in many different type of cases. That said, cache servers, which deliver most of the time the static content from your web applications, may require some specific...
