Re: State of NFV & SDN
@Mike, excellent analysis of progress, barriers, and requirements to truly transform to getting full value from NFV & SDN. 

You have hit the key points with the fact that there are unpredictable affects from the virtualization itself and this truly requires training and leadership.  It further impacts broader segments so has to embrace multiple operations and the entire network and system.

Getting comfortable leading in this environment is key.  The leading providers will have leadership that is capable of delivering "all-of-the-above".

Re: State of NFV & SDN
This is exactly why new technology needs to be used in the lab before it is let loose. 

I'm really excited for this virtualized future but I too worry a bit about things possibly going haywire.

@dcawrey: What troubles you specifically?

And, moreover, how do you feel about Oracle's recent announcement of a 100% automated network?

Re: State of NFV & SDN
@dcawrey, I agree. No technology ever works as hoped without adequate testing. Testing in a lab also require a good test plan to ensure the technology has been tested enough. It also requires testing unusual scenarios to reduce the number of unexpected defects.

Re: State of NFV & SDN
@dcawrey definitely true - there are increasingly going to be failures in order to learn new and better models.  This is where we are going to have to build new tests and validate and adjust before fully adapting and/or implementing.  We are going to have to learn to step back into development mode in order to learn the new aspects before going into production.

Re: State of NFV & SDN
One of the best ways to learn is from failure, I certainly believe in that. This is why you put things in a staging or test envrionment first.

Re: State of NFV & SDN
@dcawrey, that is the only way to truly "learn", otherwise we are just repeating what we already knew and just applying it differently.  Great concept - difficult to think about because we become vulnerable, but we will be limited unless we move forward and learn new ways.

Re: State of NFV & SDN
DHagar,

Not only that , the most important failures are not merely the ones you didn't see coming (which is how you learn to look for them) but the ones you don't understand even after they happen (because that's when you have truly crossed the frontier into the new country). I suspect that as development and deploymet of NFV/SDN ramps up, we're about to discover an extremely learning-rich frontier -- which means, at first, one that often doesn't make any sense.

Re: State of NFV & SDN
@JohnBarnes, brilliantly stated!  Exactly, it is developing new knowledge that truly moves us into new frontiers.  It is when we move from the knowns to the new unknowns that we really gain new knowledge.  That is the exciting, but sometimes scarry, space of the new frontiers that help us learn and gain skills to be successful in the new areas of opportunity (i.e., NFV/SDN, cognitive computing, etc.).

Yes and no, alas
> "'The lawyers have to be able to understand the technologies to sign off on the contracts,' he said."


In a good and intelligent legal department, yes.

Unfortunately, some contract lawyers just kind of slap their ancient boilerplate on everything and know no words other than "This is our standard [blah blah blah]" and "This is how we do it." It's a relief when you can talk to someone who's actually intelligent and reasonable about what language should say to accommodate particularized technologies and other circumstances  -- but you don't always find them.

One colleague of mine, a corporate lawyer, had the best response when it came to negotiating a corporate lease. He sent over his amendments. The landlord's contract attorney said, "This is our standard leasing contract."

My friend replied, "And these are my standard amendments to the standard leasing contract."

He got his amendments agreed to.

Re: Yes and no, alas
@Joe Stanganelli, Thanks for the insight. It is good to know that some lawyers take an interest in learning the topic they are representing. It would be great if all lawyers functioned this way.  It would improve negotiations and may help reduce confusion or issues that may arise after the contracts are signed.

Leadership
Companies that implement NFV and SDN will require senior leadership that understand the benefits of using NFV and SDN. It will also require buy-in from all stakeholders including employees. Leaders who choose NFV and SDN are technology savvy and have the ability to make sound decisions.

Change
To implement major solutions will require buy-in from all departments. Most people are reluctant to change especially employees who fear that change will result in job loss or a reduction in job duties. Companies will have to implement an organizational change management plan to address cultural issues that will arise.

Re: Change
@freehe: At the same time, the very notion of terms like "change management" can instinctively instill fear in employees (after all, if there was nothing to be afraid of, why have a name for it?).

An organization that is constantly listening to its employees, effectively engaging with its employees, and understanding its employees really has little use for anything but the most basic change-management plan because they'll already be dealing with these things.

Caution
Most companies move slowly and don't move quickly when deciding on a new technology. The best approach to implement any technology or solution is by using a phased approach. This allows time to find defects and address them.

Hesistant
Based on past experience it is understandable why enterprise customers were reluctant to put virtualized services such as security and routing onto a single box to reduce the impact to multiple services when downtime occurs.

However, it the solution provided redundancy or high uptime statistics, NFV and SDN should remain stable in any environment. The key word is "should".

Well said. I think to put everything into one box can be a risk and I can see why they might have been reluctant at first.

Re: Hesistant
They are for sure separate technologies - why are people confusing them?

Is it just because they have similar acronyms? They are really different.

Re: Hesistant
@freehe: Really, redundancy itself has its benefits (and the lack of redundancy has its downsides/risks) -- regardless of virtualization or "physicalization". It's not so much a virtualization issue.

Technology or Business?
Part of the problem might be the way that SDN and NFV are seen as technologies, rather than in terms of the new (i.e. incremental) business they *could* represent. Some CSPs seem to be treating SDN/NFV only as a technology replacement (i.e. kit --> software), where the primary business justification (as expressed) is lower cost. Hence nervousness about SD-WAN cannibalising MPLS service revenue. Adoption might pick up pace if telcos were thinking more holistically about the business opportunity, not only the technical feasibility.
