FortiGSLB Cloud™

Global Server Load Balancing Solution - Application Anywhere

FortiGSLB Cloud

Horizontal scalability is a key factor in the design of Internet services and solutions for enterprise and carrier networks. In what can often be an unstable Internet environment, the ability to easily add new network resources and applications is crucial for many business processes, policies, and procedures, such as those for disaster recovery and business continuity.

Without this flexibility, business demands often force enterprises to upgrade to bigger and more powerful devices. These upgrades can be costly and add significantly to total cost of ownership (TCO) without addressing the issues of failover and service availability.

FortiGSLB (Global Server Load Balancing) Cloud service allows users to extend this model beyond the data center, enabling customers to create new types of multi-tenant architectures and engage in big-picture thinking for delivery of network applications and services.

With a built-in setup, FortiGSLB Cloud can roll out within minutes, removing the usual complexity. More advanced users can easily enable additional policies if needed, free of charge. Learn more about FortiGSLB Cloud.

FortiGSLB Cloud Benefits

  • Advanced DNS Services and Global Server Load Balancing
  • Improve application server resource utilization
  • Rolls out in minutes (no migration/coding necessary)
  • Easy to deploy and proven use-cases
  • Integration with Fortinet Family products

Intelligent Traffic Management

FortiGSLB helps optimize end client requests for a specific domain by dynamically distributing 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 in real-time, all the 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
  • Entirely actionable/configurable via Web Interface
  • Integrated API with Fortinet Family
  • “One-Click-GSLB” – automate on-premises FortiADC configuration to FortiGSLB (via API).

Flexible purchasing options

Allow stackable license to meet customer business needs and traffic growth. FortiGSLB provide the most suitable option for customers’ business priorities and budgetary considerations.
