Multiple Wide-IPs with a single VS and Cross DC failover.

Hi,

 

I want to publish 4 services externally (internet) and internally (LAN/WAN) and want to have a cross DC failover but I have a limited number of public IP addresses so would like use a single VS. Wondering, how can I go about this?

can anyone help please?

 

Thanks.

    ​According to your question i assume you don't have 4 free IP's per DC to separate your services.

    You can create one VS per DC and segregate traffic by examining the URI and assign a proper Pool depending on the URI.

     

    Do you want to initiate DC failover manually or automatic based on a health-check result?

    If you need to failover automatically, do you want to do this per Service or for all Services of a DC together?

      Hi Nic,

       

      thanks for your swift response. yes that's right and I would like to present both option i.e. failover separately and failover for all services if possible.

       

      thanks you.

        ​I would try it the following way:

        • Create Data Center Objects
        • Create a GTM Server Object (Generic Host)  for each DC with your shared Public IP
        • Create 4 Virtual Server Objects within the Server Object, all with the same IP and Port, but assign a specific Monitor (suitable for the Application) to each of them
        • Create Pools for each Application for each DC
        • Create Wide-IP's for each Application referencing to the Pools

         

        I didn't got much into detail, but hopefully you can follow my idea anyway.
