Active/Active Clustering

In an active-active cluster, two or more instances of HAProxy Enterprise receives traffic in a load-balanced rotation. This allows you to scale out your load balancing capacity. There are several ways to achieve this setup. We cover the following methods:

Layer 4 Load Balancing

Active-active cluster Layer 4 Load Balancing

DNS Round-robin

Use DNS round-robin to rotate traffic in an active-active cluster of load balancers

Route Health Injection

Use RHI to control routing protocol announcement based on the health of the network in an active-active cluster

Real-time Cluster-wide Tracking

Use the StickĀ TableĀ Aggregator to provide real-time tracking of client behavior across a cluster of active-active HAProxy Enterprise load balancers

Load Shedding with NS1

Use NS1 Load Shedding to direct traffic to the geographically closest load balancer
