There are servers in both data centers (primary and backup) , These servers run databases and web applicationsIf from networking point of view it's ok , will both data centers (geographically distant) will be in the same AS (private AS) or the relation will be eBGP ?

Hii have a customer requesting to have a DR in another country (other than the primary one)What is the best solution to offer ? He is asking for the same IP address to move to the DR in case of the failure of the primary node is that possible ?!

From an networking point of view, Yes it is possible, and fairly easy.
Setup 2 DCs with connection between them (direct or tunnels or both) - both using BGP, and announcing the IPs to the upstream ASes.
The bigger issue will be with things like * dual active, quorums, fencing * database replication * application support of moving back and forth...
Is this the correct solution for his requirements?Would a cloud provider make more sense for this scenario?
These are all questions that can not simply be solved via a 2 min email.
