Configuring GSLB

Configuring GSLB - A GSLB deployment is the logical collection of GSLB virtual server, GSLB service, LB - virtual server, service, domain, and ADNS service. To create a GSLB site, you must configure - load balancing in the zone. You must create GSLB vservers and GSLB services for each site. You - must bind GSLB services to GSLB vservers. You must then create an ADNS service that provides - the IP address of the best performing site to the client's request. A GSLB vserver is an - entity that performs load balancing for the domains bound to it by returning the IP address of - the best GSLB service. A GSLB service is a representation of the load balancing/content - switching vserver. An LB vserver load balances incoming traffic by identifying the best - server, then directs traffic to the corresponding service. It can also load-balance external - DNS name servers. Services are entities that represent the servers. The domain is the domain - name for which the system is the authoritative DNS server. By creating an ADNS service, the - system can be configured as an authoritative DNS server. - To configure GSLB in your cloud environment, as a cloud administrator you must perform the - following. - To configure such a GSLB setup, you must first configure a standard load balancing setup + To configure a GSLB deployment, you must first configure a standard load balancing setup for each zone. This enables you to balance load across the different servers in each zone in - the region. Then, configure both NetScaler appliances that you plan to add to each zone as - authoritative DNS (ADNS) servers. Next, create a GSLB site for each zone, configure GSLB - virtual servers for each site, create GLSB services, and bind the GSLB services to the GSLB - virtual servers. Finally, bind the domain to the GSLB virtual servers.
