TLS certificates are crucial for the secure flow of web traffic, but managing these digital certificates can pose a challenge. Using an ACME-based certificate authority like Let’s Encrypt can automate and simplify the management of issuing these certificates. Certificate management in HAProxy has steadily improved over the years, allowing it to become more flexible and load certificates without restarting.

We are proud to announce that we have released HAProxy Data Plane API 2.8, available on our GitHub page. This release follows the recent HAProxy 2.8 release and incorporates its changes, along with some improvements and changes specific to the API. HAProxy Data Plane API 2.8 adds new keywords focused on QUIC, OCSP stapling, and tuning options that allow you to customize your HAProxy process using the HTTP REST API programmatically.

In this article, we’ll take you on a quick tour of the new Lua event framework shipped with HAProxy 2.8—plus demonstrate how Lua helps you further customize HAProxy’s behavior. We’ll start with a brief, high-level overview of Lua and how HAProxy uses it. Next, we’ll introduce you to the Lua event framework, show you what you can do with it, and familiarize you with its mechanics.

HTTP/3 is the latest generation of the HTTP protocol, and its ability to serve applications over QUIC offers several advantages for user experience, including reduced latency, improved reliability, and faster page loading as a result of fixing the head-of-line blocking issue in previous versions of HTTP. Both HAProxy and HAProxy Enterprise offer support for using HTTP/3 over QUIC, although the steps for enabling QUIC in HAProxy and HAProxy Enterprise are different.

HAProxy Fusion Control Plane gives you power to simplify, scale, and secure your HAProxy Enterprise infrastructure using a centralized orchestration solution, making it easier to extend HAProxy Enterprise’s security and performance across on-premises and cloud-hosted applications. With the release of version 1.1, HAProxy Fusion is more secure, more flexible, and even easier to use.

HAProxy 2.8 is now available, and HAProxy Enterprise 2.8 will be released later this year. Register for the live webinar HAProxy 2.8 Feature Roundup to learn more about this release and participate in a live Q&A with our experts.

High levels of web traffic can lead to network congestion, often causing network latency, and in some cases, outages. Traffic shaping is a technique that can help prevent network congestion by controlling how much traffic enters and leaves a network. We debuted traffic shaping in the release of HAProxy 2.7 and HAProxy Enterprise 2.7, allowing our users to control client upload and download speeds.

HAProxy Kubernetes Ingress Controller 1.10 is now available. HAProxy Enterprise Kubernetes Ingress Controller 1.10 is coming soon, and will incorporate these same features.In this release, we added partial support for Gateway API, added new Docker image tags to Docker Hub to make it easier to pull the latest version, and implemented other minor improvements. HAProxy Kubernetes Ingress Controller 1.10 is built with HAProxy version 2.7.We discuss the changes in this version below.

Spring marks a season of growth, and HAProxy was in full bloom in the Spring 2023 G2 reports. Our users continue to share their positive experiences on G2 and show how new users can use HAProxy to simplify, scale, and secure their application delivery infrastructure.
