High availaibility for highly transactional applications
I have a question re the best practice for ensuring the high availability of a few applications that are highly transactional by nature.
If I have a virtual server in DC1, that is constantly writing info to a back end DB, with a secondary server available in a secondary DC for DR purposes only, how can the BIG-IP ensure high availability in the event of the primary VM going offline? I'd plan to use the same VIP to advertise the service from both locations, just not load balance across DCs due to a few constraints in the DR DC I currently have? Storage replication is synchronous.
Any best practice/deployment guidelines? Is this a realistic requirement?
Thanks
