We do have case where the customer is looking for zero-downtime solution
for their critical applications. The solution we approached with is,
VMware HA & FT for the critical application. But these two
technologies only offers the high availability of virtual machines &
they are unaware of issue related to application services. In that case
we looked for application level clustering as well. Here we would like
to know how much application level clustering is supported along with
VMware HA & FT.
I went through a white paper which talks about symantec ApllicationHA to
be used for such environment. Does this solution guarantee the zero
transaction loss for critical application.
