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.
