Introduction

FortiMail units can operate in one of the two HA modes: Active-Passive or Active-Active. For details about HA modes, refer to the FortiMail Administration Guide.

  • Active-Active HA

    Active-Active HA is also called Config-HA. All instances in an HA group can process traffic. Azure load balancer can be used to distribute traffic to all HA members. If one member is down, Azure load balancer will be able to detect it and traffic will be redirected to other healthy members.

  • Active-Passive HA

    Azure load balancer can be used to achieve this Active-Passive HA setup. In an HA group, the primary unit processes traffic while the secondary unit works as a standby and will not process traffic. If the primary unit is down, the secondary unit will take over the role and continue to process traffic. Azure load balancer will be able to detect the healthy status of FortiMail instances and distribute the traffic.

Note

All HA units must have valid licenses to function correctly.

Prerequisites

To configure FortiMail HA cluster on Azure, you need:
