Citrix SD-WAN Platforms
Deploy SD-WAN Standard Edition instances in High Availability mode in
Azure - Release Version 10.2 and above
February 10, 2021
The Citrix SD-WAN Azure solution deploys Citrix SD-WAN in Edge Gateway Mode as a single instance,
or a cluster pair for High Availability (HA). In an HA deployment, an Azure Load Balancer (ALB) controls
the failover between the WAN interfaces of the Citrix SD-WAN appliances.
You can use the Azure load-balancer (ALB) on the LAN side to control failover on the LAN side of the
SD-WAN appliances. The Citrix SD-WAN Azure solution in HA creates two separate ALBs (each one on
LAN and WAN).
The following diagram illustrates the Citrix SD-WAN Azure HA deployment:
