Scenario: You have at least two datacenters running the same application and both datacenters are simultaneously active (business continuity) Your application is mapped on a well-defined hostname (ie. www.myapplication.com) On the first datacenter www.myapplication.com is running on IP a.b.c.d. One the second datacenter www.myapplication.com is running on IP x.y.z.t You need to monitor your application health using IP addresses that are different from a.b.c.d and x.y.z.t Solution: Use GSLB.me in round robin balancing mode Define one geohost that will be pointed by www.myapplication.com via a DNS CNAME record Create two targets, one for each datacenter and define their aliases. Targets will be healthcheck-monitored using their IP addresses but… Read More
