moving data around is external to LVS. You handle this yourself.
LVS works well for read-only. If clients are writing, something
at the back end has to propagate the writes to the other nodes on
a time scale is atomic compared to the time of reads by other users.
If you have a shopping cart, then other user's don't read your writes,
however the amount of stock will need to be decremented before the
next buyer arrives.
You have to handle all of this.
