Virtual server 2 that is setup on the LB service provider in Zone-2 represents a publicly accessible virtual server that client reaches at IP-2. The client traffic that reaches virtual server 2 at IP-2 is load balanced across VM5 and VM6 instances. At this point Tenant-A has the service enabled in both the zones, but has no means to set up a disaster recovery plan if one of the zone fails. Additionally, there is no way for Tenant-A to load balance the traffic intelligently to one of the zones based on load, proximity and so on. The cloud administrator of xyztelco provisions a GSLB service provider to both the zones. A GSLB provider is typically an ADC that has the ability to act as an ADNS (Authoritative Domain Name Server) and has the mechanism to monitor health of virtual servers both at local and remote sites. The cloud admin enables GSLB as a service to the tenants that use zones 1 and 2." msgstr "" #: ../../networking/global_server_load_balancing.rst:144 -# 16e02bcf2da14fd48ec4af740ccfc445 msgid "|gslb.png|" msgstr "" #: ../../networking/global_server_load_balancing.rst:146 -# 7f93cb0f9f2e4bc58cfc7f308c019bda msgid "Tenant-A wishes to leverage the GSLB service provided by the xyztelco cloud.
