ScaleArc HA on MS Azure
Azure supports a Layer-4 (TCP, UDP) load balancer. The Azure load balancer provides high availability by distributing incoming traffic among healthy service instances in cloud services or virtual machines in a load balancer set.
ScaleArc supports an Active-Active HA configuration for MS Azure.
