PayPal runs six data centers, each with around 60,000 containers. Their 30,000 employees spin up nearly 10,000 test environments every day — roughly 6 to 10 every minute. Each environment requires three config updates: one to create the virtual service, and additional calls to configure and deploy the applications. Do the math and you get a staggering 30,000 config updates per day.

KubeCon + CloudNativeCon Europe 2026 brought thousands of cloud-native practitioners to Amsterdam for four days of talks, demos, and hallway conversations about where Kubernetes is heading. HAProxy Technologies came as a Diamond Sponsor, and by the time the exhibition floor closed on Thursday, it was clear that the market had reached the same conclusion we had. HAProxy is the standard — and this year, more people than ever were ready to say so out loud.

Early in his career, Kelsey Hightower made a bet. The load balancer his team was running was consuming too much memory, and he was convinced he knew the fix. He told his manager: “If it doesn’t work, fire me. But I think I can make it work.” The fix was HAProxy. It was a story he shared publicly for the first time at HAProxyConf 2025, where he delivered a keynote address, “The Fundamentals.”

With NIS2 and DORA now in effect, EU organizations face a fundamental shift in how they approach security. Compliance is a standard built into every layer of your environment, from your hardware and OS to your software configuration. HAProxy alone doesn't make an organization compliant, yet it serves as a critical technical component of a strong security strategy.

The average cost of a security breach reached nearly $4.4 million in 2025, according to the publication Cost of Data Breach Report. To proactively address this substantial financial and security risk, Infobip, a global cloud communications platform, used HAProxy Enterprise to implement a security and uptime framework that is both highly modular and highly performant.

The Ingress NGINX project is winding down. For many organizations, this means planning a migration for critical infrastructure. While the HAProxy Kubernetes Ingress Controller is the natural successor for these workloads, a "rip and replace" strategy isn’t always viable. You might have complex configurations, customized annotations, or deployment freezes that make a sudden switch risky. There's a lower-risk path: Place HAProxy in front of your existing Ingress NGINX deployment.

Service mesh was a good start. But the industry needs something more comprehensive. At KubeCon + CloudNativeCon Europe 2026, HAProxy's Baptiste Assmann presents a new architectural vision: Universal Mesh — a boundary-first approach that unifies North-South and East-West traffic management into a single platform, without sidecar overhead.

This is how PayPal reduced latency by 24% while increasing security and convergence across their business units. By utilizing a Universal Mesh built on the foundation of HAProxy, they were able to build a private connectivity layer despite major IP overlaps.

One of the biggest challenges for organizations that have adopted microservice architecture is the lack of architectural, operational, and organizational standardization. After splitting a monolithic application or building a microservice ecosystem from scratch, many engineers are left wondering what's next. In this practical book, author Susan Fowler presents a set of microservice standards in depth, drawing from her experience standardizing over a thousand microservices at Uber. You'll learn how to design microservices that are stable, reliable, scalable, fault tolerant, performant, monitored, documented, and prepared for any catastrophe.
