Global server load balancing

For organisations with websites or online applications that have a very limited tolerance for downtime, NetBenefit has designed a global server load balancing (GSLB) service called SiteRedirect.

Global server load balancing is different from dedicated or shared load balancing in that the service is DNS (Domain Name Server) based.  Your managed servers will be located in two different data centres.  SiteRedirect then continually polls the IP addresses of the managed servers to check for availability.  In the event that SiteRedirect identifies a server is not available in the primary data centre then the service will failover to the servers located in the secondary data centre.  It is not necessary to replicate the full managed hosting solution in the second centre but the solution still requires more investment than shared or dedicated load balancer services.

Global server load balancing provides a guaranteed level of availability because it is not dependent upon a single physical data centre location.  SiteRedirect is based upon global server load balancing devices located in three different data centres providing a highly resilient platform capable of withstanding multiple failures.

Why choose global server load balancing?

GSLB technology is one of the most resilient techniques available to distribute load between server infrastructures in different geographic locations and is the de-facto standard used by many large web sites.

It leverages the DNS system already at the heart of the Internet to distribute traffic between independent data centres. By providing web services in multiple physical locations with no interdependence between physical sites, NetBenefit’s SiteRedirect service provides a load balancing service that is highly resilient – even in the event of the catastrophic failure of an entire data centre site.
