Deploying Additional Access Gateway Appliances for Load Balancing and Appliance Failover
You can install multiple Access Gateway appliances in your environment for the following reasons:
- Scalability. To accommodate more users, you can install additional Access Gateway appliances in your network. To provide fault tolerance, you can deploy multiple appliances behind a load balancer to balance the user load between Access Gateway appliances.
- Appliance failover. If an Access Gateway fails, you can install additional Access Gateway appliances to ensure that the internal network remains available to remote users.
Note: To address appliance failover only, you can configure one Access Gateway as the primary and one appliance as the secondary. If the primary Access Gateway fails, user connections are directed to the secondary Access Gateway. For more information about this configuration, see How Appliance Failover Works on Access Gateway 5.0.
