Leverage FortiGSLB Cloud to keep your businesses online in the event of localized traffic spikes or outages.

Fast, Secure and Intelligent
FortiGSLB helps optimize end client requests for a specific domain by dynamically distributing workload across virtual servers, data centers and locations. In particular, FortiGSLB incorporates several techniques to:
- Direct internet application traffic to multiple servers behind one single external IP address
- Let Customer define policies for the dynamic selection of preferred pools of servers

FQDN object will map a fully-qualified domain name (FQDN) to a set of virtual servers (pool), and the administrator can do the global geographic policy in this object. The administrator has defined the pool objects and the location objects. A pool object can bind a location object as a member for the FQDN object, and the FQDN object can define multiple members. When the DNS queries try to reach FortiGSLB Cloud, the service will do the first level load balancing according to the virtual server pool selection method. The DNS queries will be forwarded to a pool, and the virtual servers will respond according to the pool's preferred schedule methods for the queries.

FortiGSLB uses health checks to poll the members of the generic host to test whether an application is available.

Pool object is a group of virtual servers that perform the same role on the network. The administrator puts the virtual servers with the same role into one pool. The administrator can also divide one pool into several sub pools according the geographic location.
