On Tuesday, November 1, the OpenSSL project released a new version of OpenSSL (version 3.0.7) to patch a high severity vulnerability in versions 3.0 and above. If you are using OpenSSL version 3.0 or above with HAProxy, you should update to OpenSSL version 3.0.7...
Fundamentals: What Sets Containers Apart from Virtual Machines
Containers have fast become one of the most efficient ways of virtually deploying applications, offering more agility than a virtual machine (VM) can typically provide. Both containers and VMs are great tools for managing resources and application deployment, but what...
Fundamentals: Application Acceleration and the Benefits for your Service Delivery
Application acceleration is all about improving the responsiveness of a digital service. When clients access web applications, they are expecting near-immediate feedback from servers. Maintaining that level of performance requires ensuring the right resources are...
Fundamentals: What is an API Gateway?
When talking about managing web applications and the services they provide, the term “API gateway” is often thrown around, but what does it mean? In order to unpack how a gateway functions, we first need to understand what an API is. Application Programming Interface...
Verify OAuth JWT Tokens with HAProxy
With HTTP REST APIs serving as the backbone of modern web applications, securing those APIs presents a critical challenge for organizations. APIs are typically designed to be discoverable, self-documenting, and easily consumed by a range of programming languages, and...

Fundamentals: High Availability and the Role of a Reverse Proxy
HAProxy. High availability and a reverse proxy–it’s in the name, but what does it all mean? Before understanding how the two concepts work together in the load balancing space, we need to unpack the basics of high availability and how a reverse proxy functions. In...
Path-based Routing with HAProxy
If you host dozens of web services that reside at various subdomains, TCP ports, and paths, then migrating them to live under a single address could simplify how clients access them and make your job of managing access easier. It would mean moving from a hodgepodge of...
Restrict API Access with Client Certificates (mTLS)
An application programming interface (API) provides access to the features of a business application, but with the visual elements stripped away. By using APIs, devices like tablets, self-service kiosks, point-of-sale terminals, and robotic sensors can connect up to...
