GitHub Load Balancer Director vs HAProxy: What are the differences?
GitHub Load Balancer Director: GitHub's open source load balancer. GLB Director is a Layer 4 load balancer which scales a single IP address across a large number of physical machines while attempting to minimise connection disruption during any change in servers. GLB Director does not replace services like haproxy and nginx, but rather is a layer in front of these services (or any TCP service) that allows them to scale across multiple physical machines without requiring each machine to have unique IP addresses; HAProxy: The Reliable, High Performance TCP/HTTP Load Balancer. HAProxy (High Availability Proxy) is a free, very fast and reliable solution offering high availability, load balancing, and proxying for TCP and HTTP-based applications.
GitHub Load Balancer Director and HAProxy can be primarily classified as "Load Balancer / Reverse Proxy" tools.
