Hello,
I am new to this list and wanted some guidance on a Cisco solution for the
following requirement.
We have a client (bank) who have two sites - A and B - both located in
difference towns. A is the HQ and B is to be their Disaster Recovery (DR)
site. Client has requested for -
* Internet bandwidth (~ 20 Mbps) to be supplied to Site A, and if there is any
failure there, this bandwidth is to be re-directed to B.
* The services to be hosted by the bank is basically their Internet Banking
Platform (web-based) and mail. The databases for both services will be
replicated across A and B. Client will handle this, but we will provide
communication channel between A and B.
A and B are to be connected via fiber through intermediate IP-based routers.
(There is no MPLS.)
So my question is what is the best way of handling the failover for both their
services ? DNS changes ? Is there anything better I can do with a Cisco
product placed at A and B ? I know Linux has a Virtual Server implementation
and I see Cisco's ACE does something similar though I am not an expert with
Cisco products. And for the secure channel to enable the databases at the
sites to synch up, should I be thinking of IPSEC ?
One of our suppliers mentioned something about using HSRP or VRBP. I am yet
to do some research on that.
Any suggestions would be appreciated.
Thank you,
Sanjeev
