Internet protocols are the lifeblood of internet communication, powering important connections between servers, clients, and networking devices. These rules and standards also determine how data traverses the web. Without these protocols, internet traffic as we know it would be severely fragmented or even grind to a screeching halt. And without evolving protocol development, the web couldn’t properly support the applications driving massive traffic volumes worldwide (or vice versa).

Managing your load balancer instances is important while using HAProxy. You might encounter errors, need to apply configurations, or periodically upgrade HAProxy to a newer version (to name a few examples). As a result, reloading or restarting HAProxy is often the secret ingredient to restoring intended functionality. Whether you’re relatively inexperienced with HAProxy or you’re a grizzled veteran, understanding which method is best in a given situation is crucial.

The curtain rose and fell on another spectacular Black Hat USA, the conference set against the backdrop of fabulous Las Vegas in the Mandalay Bay Convention Center. We knew upon hitting the Strip that all the glamor and neon lights were just the preshow for the main event: innovation and the latest in cybersecurity. We couldn’t wait to show attendees and fellow vendors what we had to offer.

HAProxy offers a powerful logging system that allows users to capture information about HTTP transactions. As part of that, logging headers provides insight into what's happening behind the scenes, such as when a web application firewall (WAF) blocks a request because of a problematic header. It can also be helpful when an application has trouble parsing a header, allowing you to review the logged headers to ensure that they conform to a specific format.

The Kubernetes networking landscape is shifting. The traditional Kubernetes Ingress approach is being complemented and, in some cases, replaced by a more powerful, flexible, and extensible standard: the Kubernetes Gateway API. Kubernetes has become the go-to platform for orchestrating and managing containerized applications. A key aspect of Kubernetes that's crucial for the functionality of these applications? Networking.

SysOps teams know how crucial observability is to maintaining around-the-clock infrastructure health. And while HAProxy already provides reliable logging and stats (for diagnostics and monitoring), what if you could supplement those with a real-time alerting system? That idea inspired our initial inclusion of mailers in HAProxy. Since then, users have been asking for deeper mailer customizability—and we’re thrilled to deliver that with Lua-based email alerts in HAProxy 2.8.

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.

There’s no shortage of articles on CI/CD and how to run a configuration validation utility before reloading or restarting a service, but this type of validation is not the same as acceptance testing. Furthermore, these validations don’t always give you (or your leadership team) the confidence to allow you to make big changes to your Production Infrastructure during normal business hours, often preferring to err on the side of caution and scheduling a maintenance window when you might prefer to be in bed.

When it comes to TLS in Kubernetes, the first thing to appreciate when you use the HAProxy Ingress Controller is that all traffic for all services traveling to your Kubernetes cluster passes through HAProxy. Requests are then routed towards the appropriate backend services depending on metadata in the request, such as the Host header. So, by enabling TLS in your ingress controller, you’re adding secure communication to all of your services at once. HAProxy is known for its advanced support of the important performance-oriented features available in TLS.

Performance has never been more important than in a cloud-native world. Cloud-hosted resources cost money and a slow-loading application can cause a suboptimal ROI. Have you taken the time to tune your Kubernetes ingress controller and proxy? Many organizations don't until it's absolutely necessary, and most users will typically run a default, out-of-the-box configuration. In this demo, we benchmark five popular ingress controllers and put them head-to-head against each other with their default configurations.

Helm, the Kubernetes package manager, revamps the way teams manage their Kubernetes resources and allows them to deploy applications in a consistent and reliable way. It is a valuable tool in a continuous delivery pipeline, with support for quick updates and rollbacks. At HAProxy Technologies, we offer Helm as the preferred method for installing the HAProxy Kubernetes Ingress Controller, and we’ll show you how to customize that installation to fit your use case.

This presentation will describe how Go and other developers can integrate with HAProxy via the HAProxy Data Plane API and it’s packages. We will explain the motivation behind this new product and provide an overview of how we used the OpenAPI specification, including how models and server stubs are generated using go-swagger. We will delve deeper with describing client-native and config-parser packages and explain how and when to use them, by showing how we use them in our HAProxy Kubernetes Ingress Controller. We will also briefly touch on how you can contribute to these projects.

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.
