GSLB

 

Global Server Load Balancing (GSLB) is an extension of load balancing functionality, which is highly efficient in avoiding downtime. Based on the nature of deployment, GSLB represents a set of technologies that is used for various purposes, such as load sharing, disaster recovery, performance, and legal obligations. With GSLB, workloads can be distributed across multiple data centers situated at geographically separated locations. It is used to manage the traffic flow to a web site hosted on two separate zones that ideally are in different geographic locations. GSLB can also provide an alternate location for accessing a resource in the event of a failure, or to provide a means of shifting traffic easily to simplify maintenance, or both.

 

In the GSLB tab, you see a list of GSLB rules created by your service provider.

 
In the Details pane, you see the following details:
  • ID: ID of the GSLB.
  • Service Type: The transport protocol to use for GSLB.
  • Region: The region of the GSLB.
  • Domain: The domain associated with the GSLB.
  • Account: The account on which the GSLB rule is applicable.
  • Algorithm: The algorithm used to load balance the traffic across the zones.
  • Domain Name: The domain name of the GSLB rule.
