GEO is available as standard with your support subscription on all LoadMaster load balancers across all hardware and virtual models and platforms. GEO is also available as a standalone virtual appliance.
Skip to main content. Please check your inbox for your exclusive Webinar link. Under normal operation, GEO is configured to direct traffic to the primary datacenter. All GEO instances and LoadMasters at each location determine the health of local virtual services and share status and performance information across all locations. When the GEO partners determine that the primary site has failed and that the secondary site is healthy, they direct ALL traffic to the secondary datacenter.
Automated Scaling for High Availability Finally, GEO can also help you cost-effectively manage expansion into public clouds to provide on-demand service expansion during high volume periods, which uses elements of both Active-Active and Active-Passive configurations.

To enable the new service, go to the zone created zvnlb. At this point, the host www. The TTL serves to tell the recursive server or local resolver how long it should keep said record in its cache. So a lower value configured faster the changes are detected. The following DNS request shows the Nameservers configuration for zvnlb.
Now, use your current DNS servers to resolve a host for example www in this zone:. As it is shown, currently the host As soon the host is not reachable for example, the http service in As soon as the application server fails, the DNS resolution will change the host to the Data Center 2.
Once the host in the Data Center 1 is up the fail-back will be applied automatically. Now, add it in the zone zvnlb. To test it, try to resolve the host www. Note that the DNS resolver returns both application servers instead of one like the Disaster Recovery case.
Once the host has a failure, the DNS resolution will change automatically.
