GSLB provides Multi data center, Multi-cloud, and Hybrid cloud Load Balancing and Fail over.

Why Do I Need Global Server Load Balancing?

Global Server Load Balancing (GSLB) gives you ultimate control in your application delivery service. Ensure that users from certain geographic locations are sent to the right data center. Ensure that different content is served (or blocked) to different users, depending on several criteria such as the country that the client is in, the resource they are requesting, the language, etc.

How Does Global Server Load Balancing Work?

Global Server Load Balancing (GSLB) is typically used to provide data center failover or to enhance end user performance by directing users to their closest data centers using geolocation. GSLB is a DNS based system that manipulates the DNS response based on the availability and performance profile of the data centers.

  • Resiliency and Disaster Recovery
    Run two data centers in an Active-Passive architecture so that if one data center fails, traffic will be sent to the other.
  • Load Balancing and Geo-Location
    Distribute traffic between multiple data centers in an Active-Active architecture based on specific criteria including: fixed weight, round robin, data center health check, geo-location of the client etc.

How Do I Deploy Global Server Load Balancing?

The GSLB solution runs as an integrated, containerised application on the Edgenexus load balancer in a secure environment. Global Server Load Balancing has traditionally been complex to setup and configure but Edgenexus simplifies this, offering an easy-to-use, intuitive GUI.

The Edgenexus Global Server Load Balancer container for Docker can be downloaded from the Edgenexus App Store.

The level of administration, management and monitoring offered by Edge ADC is far superior to all the alternative solutions we considered. In fact the Edgenexus appliance is simpler to maintain and use than the F5 and Citrix NetScaler solutions used in other SDL locations.
