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

possible ?!

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.
