Hi all,
I've heard a lot of claims recently about virtualisation / Cloud service, but ultimately, transactions must be committee to Point A and then replicated Point B, and as I see it no Virtualisation/ Cloud service can do that.
Or am I wrong?

Well first off virtualization is not synonymous with cloud services although cloud services rely heavily on virtualization.
And why would either of those matter, either a transaction is committed or it's not, why does it matter whether it's on a physical, virtual or cloud machine?

You have most definately misunderstood what virtualisation is. It is nothing more than the ability to allow multiple OS installations to coexist on a common hardware platform.
Never, ever think that it is a replacement for other technologies such as replication, mirroring, clustering as so on.
And one more thing: Just because Cloud Services configure their virtualisation layer to be highly redundant / available the need for a good backup and disaster recovery plan is not reduced.
PS: A discussion about transactional activity within the database is redundant in this post. It isn't affected by virtualisation.
