I had been extremely impressed by them, especially when we were encouraged by @AGSaidi to switch to the new Arm Large System Extensions (LSE) atomic instructions, for which we already had some code available but never tested on such a large scale, and which had totally unlocked the true power of these machines. So that looked like a fantastic opportunity to combine everything and push our benchmar

In this presentation, Joe Williams describes the architecture of the GitHub Load Balancer (GLB). GitHub built a resilient custom solution on top of HAProxy to intelligently route requests coming from a variety of different clients including Git, SSH and MySQL. The GLB is split into two major components: the GLB Director and GLB proxies. The latter is built upon HAProxy, which provides many benefit

HAProxy 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 also paves the way for HAProxy to support newer versions of HTTP-based technologies and protocols at a faster pace. Today, with the re

HAProxy’s high-performance security capabilities are utilized as a key line of defense by many of the world’s top enterprises. Application-layer DDoS attacks are aimed at overwhelming an application with requests or connections, and in this post we will show you how an HAProxy load balancer can protect you from this threat. This post describes techniques that utilize ACLs, maps, and stick tables. 

The monumental stable release of HAProxy 1.8 is here! The HAProxy 1.8 release candidate 1 (RC1) has been published by the R&D team here at HAProxy Technologies. This blog post will take you through some of the release highlights, new features, and configuration examples to get you up to speed. For HAProxy 1.8, our development team was primarily focused on two areas: Performance and Application Acc

HAProxy 1.8 and newer allows you to use DNS service discovery to detect server changes and automatically apply them to your configuration. HAProxy is a mature, high-performance software component that’s been reliably serving the load balancing and ADC markets for over 15 years now. Over time, the role and functionality required from HAProxy have evolved significantly. When HAProxy was first releas

HAProxy Technologies’ R&D has released a patchset to enable seamless reloads of HAProxy without dropping packets in the process. The patch set has already been merged into the HAProxy 1.8 development branch and will soon be backported to HAProxy Enterprise 1.7r1 and possibly 1.6r2. This work was done as part of a larger roadmap initiative at HAProxy Technologies to support more microservices use c

HTTP protocol is connection-less and only the client can request information from a server. In any case, a server can contact a client. HTTP is purely half-duplex. Furthermore, a server can answer only one time to a client request. Some websites or web applications require the server to update client from time to time. There were a few ways to do so: the client request the server at a regular inte
