Multisite Auto-Failover Solutions
Hi,
I'm hoping that someone could help me with finding a solution for the infrastructure we have in place. We have several servers hosted on 2 sites, Site A and Site B. Both sites is independant of each other, ie. separate entities with separate IP addresses. What we have planned is to have Site A to be the primary site while Site B will be the backup site. So basically, if Site A goes down due to whatever reasons, all traffics to domains owned by us will be automatically redirected to Site B. Someone suggested using the Primary and Secondary DNS to point to the 2 sites, but I don't think that would be a good solution as most ISP cache theirs and the failover would not be immediate. So do anyone have any solutions as to how we can best overcome this. Thanks.

first you must have a program or such that transfers the updates or updates the servers so thet both servers are up to date then you must have something thats checking if a server is offline then you just imideate rederect to site a or b depending on it if its online or offline the user notices nothing
