HAProxy - HAProxy is the best open source load balancer without a doubt

Perplexed by proxy?! Ruffled by reverse proxy?! We’ve all been there. Honestly, sometimes I think the language we use makes things sound way more complicated than they actually are.

We've had a few concerned customers asking about the Google disclosure of the recent huge DDoS attack, and the potential underlying vulnerability in some HTTP/2 servers.

SSL/TLS termination is the most regularly implemented kind of SSL/TLS offload.

How many times have you looked at the HAProxy report and thought, what on earth is this all about?! What are the busiest times on my Loadbalancer? Which Real Server is busy? How much traffic is going through my VIPs?

Working with this Snapt customer to support them with the urgent migration of all their critical applications.

With our recent release, you can now use the new Prometheus exporter to export the HAProxy metrics into an existing Prometheus environment.

I was genuinely shocked and a little sad hearing the news that SNAPT has gone bust. They were a great company, with a nice product and more importantly — nice people.

Growing customer demands are forcing technology providers to reconsider their approach to high availability and scalability.

A while ago I was asked if it would be possible to apply some general rate limiting in HAProxy and the WAF, in order to help prevent DOS-style attacks on a customer's servers.

At Loadbalancer.org, our heroes are open source. And for good reason. Open source software plays an intrinsic part in our company, products, and services.

We love complex rules. Although, we have seen some pretty scary config files.

All Secure Web Gateways require client IP transparency in order to implement any proper kind of security and authentication. Which can be a real pain if you have a load balancer in the middle.

So you're probably here because you want to know how to achieve an A+ rating for your SSL web server on Qualys. A quick fun fact: did you know the A+ and A rating are in fact the same?

Microsoft Dynamics is a critical ERP and CRM tool, used every day by businesses all over the world. The application therefore needs to be highly available and scalable.

Here our Loadbalancer.org Founder, Malcolm Turnbull, offers advice to anyone thinking of moving from HAProxy to a proprietary load balancer.

Control how HAProxy will be started, stopped, restarted, reloaded, or monitored.

We’re always keen to give back to the community that writes such great software – our new SNMP agents and MIBs for HAProxy make monitoring your Virtual Services and Real Servers a breeze.

Direct server return, direct routing - no matter what you call it, using DSR maximises the throughput of return traffic and allows for near endless scalability. Here's why we still love it.

A critical vulnerability in HAProxy’s HTTP/2 HPACK decoder in versions 1.8 and above has been discovered. This does not impact the majority of Loadbalancer.org customers.

We recently attended the inaugural HAProxy Conference in Amsterdam. Loadbalancer.org are proud to be part of the HAProxy community and we were glad to be involved with the event.

Loadbalancer.org were the original sponsors of the external health check mechanism in HAProxy. We think it's an invaluable tool when you need something a bit special.

An incorrect frame length check could result in a read-past-bound which can cause a crash.

A critical security issue has been found in HAProxy, leaving certain systems vulnerable to remote attack. We want to keep you informed, and we understand that this news might cause you some anxiety. But be reassured - most of our customers won’t be affected.

It's really annoying when people believe that something traditional (proven to work) is somehow worse, than something that is modern (looks like a cool idea).

It’s no big secret that a single processor can only handle so much processing in a given time. So what happens when you reach the limits of what a single processor can handle? Simple, you add more processors.
