Malcolm Turnbull, Co-Founder of Loadbalancer.org, is a foundational authority with 20+ years of uptime industry experience. As the original engineer, his expertise is based on championing open-source load balancing (HAProxy/LVS) to deliver clever, not complex, solutions. He provides deep, technical insight on high-availability, performance optimization, security, and software development philosophies. He also loves to play devil’s advocate in any conversation!
We've had a chat about this internally and thought that it would be nice to have a permanent post on the blog that we change on the fly as and when customer requirements change...
In general when you are load balancing a cluster you can evenly spread the connections through the cluster. However, with some applications, you might get very high load from just a few users doing heavy work, which can compromise performance...
Some of the most common questions we get at Loadbalancer.org are performance related. It is quite difficult to give a straight answer to these questions as the real answer is often slightly unsatisfactory...
I must confess, at certain times it has looked like open warfare would break out between the support team and development team at Loadbalancer.org over the last few months...
In Exchange Server 2013, there are two basic building blocks – the Client Access Array and the Database Availability Group (DAG)...
Any engineer dealing with PCI DSS compliance issues probably looses a little bit of the joy in life...
I get quite frustrated with benchmarks because they are very hard to perform properly, and even when you do them properly its very hard to get any useful data from them...
Ok, before I start to fan the flames, let me start with the usual caveat; GSLB doesn't ALWAYS suck — just more often than you'd think, for these reasons.....
I’m excited and slightly scared by our latest product! Excited because I've become slightly addicted to launching multiple instances in different parts of the world and load balancing the traffic seamlessly. Scared because this could change our whole business model...
I've previously blogged about how to get TPROXY and HAProxy working nicely together, but what if you want to terminate SSL traffic on the load balancer to use HAProxy to insert cookies in the standard HTTP stream to the backend servers?..
Some vendors make a fair bit of hype about their products enabling 99.999% availability out of the box...
If you use HAProxy as the load balancer then all of the backend servers see the traffic coming from the IP address of the load balancer...
