Global server load balancer



  • Hi everybody  thanks for allowing me to discuss in this forum,

    we have two data-centers at different geographical location  hosting  WEB SERVERs ( main and stand by site).  Both sides  Pfsense is used as gateway ..
    The public ip is as follows
    20.20.20.20… main datacentre web server
    30.30.30.30    standby datancentre web server

    Now i want to make HA  between these two  sites.  So that, the service will not be hampered , even if one site is down..

    I tried to create DNS entry with these two ip  at ISP DNS for www.xxx.com , but it is resolving in round robin manner and clients will not automatically fall into  other datacentre unless  i run flush dns command  in PCs.

    I have Vpn connectivity between these two data-centers..

    Please provide a solution where can i make global server load balancer between these two  IPs  and one should resolve the live datancentre web server , if other site fails..

    any help is greatly appreciated

    regards
