Two data centers and fixed IP
Hi,
I wonder what could be solution for such a case:
- Two DC
- Each DC connected via different ISP with different public IPs
- GTM's used to direct traffic for given FQDN to active VIP in correct DC
- FQDN is of cource static but A record returned is changing, so different IP behind some FQDN depending on situation
- Services offered by customer are accessed by plenty of external apps that are using hard coded IP instead of FQDN for sending requests (mainly banks).
- Customer has no way to force external parties to change code in applications.
Is there some way to configure GTM/LTM system so independent of in which DC given VIP is active the same IP is returned for given FQDN. Is that at all issue related to GTM/LTM system or rather to external ISP/routing infrastructure?
