Global Server Load Balance (GSLB) Cloud is a DNS-based service that helps to ensure business continuity by keeping an application online and available when a local area experiences unexpected traffic spikes or network downtime.
GSLB enables you to deploy redundant resources around the globe to maintain the availability of your business critical applications.
Intelligent Traffic Management
FortiGSLB optimizes client requests for a specific domain by dynamically distributing the workload across virtual servers, data centers, and locations. You can route traffic to your network resources based on geography, server performance (CPU/memory) and load, measured client and network performance, weighted distributions, consistent (sticky) routing, and more.
Advanced Health Check
FortiGSLB Cloud monitors your application end points or your cloud services based on configurable health checks. All of your resources are monitored continuously in real-time. Customizable health checks let you choose your protocol and parameters, from simple ping to an Application layer-7 response content match.
Seamless failover to second closest service
- Zero software/hardware needed
- No hardware performance bottleneck
- Managed via web interface
- Integrated API with Fortinet family
- One-click GSLB: Automate on-premise FortiADC configuration to FortiGSLB via API
Highlights:
Autoscale solution:
- No hardware performance bottleneck
- Stackable license to increase performance
- Eliminates need to accurately estimate application volume in advance
Intelligent traffic management:
- Advance load balancing according to server/site availability
- Supports DNS services and load balancing-based application health
Improved performance:
- Deliver to closest servers based on geography
- Performance-based routing based on client-driven performance metrics
- Reduced latency and increased application responsiveness
Improved risk management:
- Automate detection and execution of failover services
- Customizable health checks with choice of protocols and parameters: Ping, DNS, TCP, HTTP/S, layer-7 Response code or content
FortiGSLB Cloud provides load balancing across multiple datacenters (active/active) and cloud applications based on GSLB Cloud Policies, with site selection according to application/server availability (health checks) and client geolocation.

- Monitoring and site overview
- DNS history statistics
Health Check
- Support for various application/protocol validations:
- TCP port
- TCP echo
- ICMP
- DNS
- UDP
- HTTP (GET/HEAD/Connect)
- HTTPS (SSL validation, TLS 1.2, 1.3)
- Health check match for user/password, hostname, string validation, response code
- AND/OR relationship
Load Balancing
- GEO: FortiGSLB performs load balancing according to the request’s source geographic location.
- Least connection: FortiGSLB Cloud load balances traffic to the virtual server with the least connections.
- Connection limit: FortiGSLB Cloud performs load balancing according to the virtual server connection limit determined by the virtual server weight. The greater a virtual server weight, the more responses it gets.
- Bytes per second (BPS): FortiGSLB Cloud load balances traffic to the virtual server with the least BPS.
- Server performance: FortiGSLB Cloud load balances traffic to the server with the lowest load (memory and CPU). Virtual servers with better server performance in the CPU or memory (whichever one you give more weight to) respond.
