Transparent HAProxy in Azure using TProxy

Posted by Ben Cabot 28th September in AWS and Azure

We all know that the built-in Azure load balancer is perfectly functional, but sometimes you need a proper load balancer. HAProxy is an excellent choice if you need layer 7 functionality, but its a full reverse-proxy, so the application thinks that all of the traffic is coming from HAProxys IP - rather than the clients. So what can you do if the load balanced application needs to know the real clients IP address in Azure?

Integrating your load balancer with auto scaling groups in EC2 (Amazon AWS)

Posted by Ben Cabot 11th May in AWS and Azure

Amazon's auto scaling feature is a great tool to ensure that you always meet your desired server capacity. This helps you keep up with the demand from your users while keeping costs down. Amazon's ELB ties in well with auto scaling groups automatically load balancing servers that have been brought up as the result of an auto scaling action.

Cloud based GSLB made simple with concierge service from Loadbalancer.org

Posted by Theo Harvey 12th September in AWS and Azure

Anyone who has been watching Loadbalancer.org over the last few years will have noticed the things that we don't like :-). We've made it pretty clear that we don't like load balancing firewalls and we've also been pretty reluctant to turn our load balancers into a GSLB. Why? Because putting PowerDNS on a load balancer is a daft thing to do, that’s why.

Transparent Load balancing with HAProxy on Amazon EC2

Posted by Ben Cabot 10th April in AWS and Azure

This is a quick guide on how to setup transparent mode on HAProxy in Amazon's EC2. One of our favored methods of load balancing is using Layer 4 DR because it is transparent and fast. Unfortunately because of Amazon's infrastructure this is not possible in EC2 so we need to use another method which means we are left with layer 4 NAT and transparent HAproxy using TProxy.

Load balancing UDP on EC2

Posted by Ben Cabot 28th August in AWS and Azure
