Fair enough, but you actually haven't answered my question about why you think that VNFs such as vTMS can not be implemented in a horizontal scaling model? 
In my opinion any NF virtual or physical can be horizontally scaled.

Right, and of these 3 you mentioned, what is it that you'd say operators are waiting for to get standardized, in order for them to start implementing network services orchestration?

Agreed, all I'm trying to understand is what makes you claim things like: progress is slow, or there's a lack of standardization, or operators need to wait till things get standardized in order to start doing network service orchestration... 
I'm asking cause I just don't see that. My personal experience is quite different to what you're claiming. 

Yes the landscape is quite diverse ranging from fire and forget CLI scrapers (Puppet, Chef, Ansible, SaltStack) through open network service orchestration frameworks all the way to a range of commercial products for network service orchestration, but the point is options are there and one can start today, no need to wait for anything to get standardized or things to settle.
