Re: Al the more complex
to be sure, the degree of complexity/difficulty for CSP's to execute on the potential of "pure NFV" service in which everything is managed in the automated, fault-tolerant, self-healing, virtualized environment is a marathon with loads of fits and starts along the path.

However, I have recently met with several technology leaders at various CSP's and I am seeing leadership around intelligent roadmaps for the "evolution" (as you accurately state, "transformation" may not be in their organizational DNA). They continue to seek out companies who are willing to partner with them in building out their next generation OSS/BSS platforms.

Re: Al the more complex
@kq4ym - thanks for your comment.

I think it's useful to distinguish hybrid services from hybrid infrastructure.

I tend to agree with you that hybrid *services* represent additional complexity that can (and quite possibly should) be avoided - certainly initially and possibly forever. Initiatives like AT&T's Domain 2.0 are evidence of this.

However, what I was getting at in my post is that the debate around should/will hybrid services ever become a reality is a red-herring, because hybrid *infrastructure* is unavoidable and presents an immediate challenge about which carriers are being given little guidance.

For example, currently, carriers have little choice other than to provide WAN connectivity to VNFs using their "classical" network, which, even if it does look like a simple point-to-point link to the NFVI, in reality it is a complex mix of - old-world - technologies.

Re: Al the more complex
Headache it is for all it does seem. Maybe, hybrid the wave of the future, because it's becoming too complex for the present? Until there room for investment with clear ROIs it's going to be not just around the corner most likely.

@dcawry

Thanks for your comment!

As an aside, I think that systems complexity is going to increase irrespective of whether hybrid services become the norm - or indeed appear at all. Technologies like SDN and NfV have more, not fewer moving parts than "classical" networks, and those parts move more quickly and more autonomously.

I do strongly feel that stronger guidance based on what is actually happening in the field, rather than on what *could* hypothetically happen, or on what architectural frameworks suggest *should* happen, is required to help operators steer successfully through the impending changes.

Al the more complex
Although I am positive there are many who wish systems were becoming less complex, unfortunately that's not a reality.

Hybrid systems are going to become completely normal, and people are simply going to need to adject to this paradigm.
