Interesting course. Thank you.

What kind of contingency plan should be put in place in case automation fails?

A major barrier to Automation is the resistance to change of the organization: its processes, assurance policies and people skills.

Slide 8: A CSP can be selling both applications and network services. In such case, are two different automation solutions required to be implemented by the same CSP?!

Automation is also expected to replace the work done by provisioning teams, thereby leading to operational costs reduction.

Thanks a lot Stefan, Kelsey, very good presentation.

costs and skills required for automation

Automation add security, reduced human errors & let better service delivery

Poll 1: Cost saving by time saving

Poll 1: Streamline Project Management


Listening in from Portland Oregon. It is a clear sunny day

@Transmis the lecture is audio only, but there are slides in the "Special Educational Materials" section above the live chat window.

@Ravibeneditti - It scolls fine on my phone, but I have an iPhone so it could be the Android, like you said. It could also be a WiFi issue. 

Ahhh...  This restart upon scroll only happens on my Andriod phone,, not on laptop. I can manage from here, but am wondering if the player is simply not mobile friendly?

Has the ability to scroll back and forth in the archived talk been disabled? Any type of scrolling causes the entire talk to start over!

So glad that this presentation is available in the archive.

Isn't virtualization plug-and-play?

Listeners, Slide 20: if there is a problem in accessing the link (at the bottom) through "https://", try "http://" instead, it works! --> "Service Orchestration and Network Virtualization: A Lifecycle View", makes the concepts in the SoftBank example more clearer

@Stefan: Slide 13, wish you had explained "State Convergence" more! Hope there are audit schemes implemented in these architectures to ensure consistency from data corruptions etc.

Thx Stephen, we really apreciate your advise on proper data modelling at the two layers. Softbank example was indeed useful to apreciate the phylosophy you oulined. Enjoyed your talk!

@Stefan: your top/bottom layering/separation with good APIs and analysing appl centric vs network centric services differently makes the understanding/apreciation of automation (assesing available tools) better. Thanks for that first level simplification!

listening offline from Bangalore!

Thanks Stefan for a good introduction to automation. Which international standards body is overseeing the development of automation for Telco networks?

Thank you for having the archive.  Great introduction to Automation Stefan.

What are your thoughts around Security and Automation?

How does Automation affect the skill level / skill set of Operations Staff?  Does it?

Great to get a Cisco perspective here!

streamlined operations, reliability/repeatability

Glad you liked the slide deck, @tiggerho0!

cost savings, agility


Weather is great here in HK, but timing not so good
Last of the series.. aga8n attending remotely n offline

i reacall my answer on the Softbank use-case being a mix of app and nw centric. No it is purely network centric in that the "apps" are packet-forwarding/processing apps and can not be treated in the generic way. See my definitions on the slides.

@Stefan Thank you for those additional links too!
Wondering if there are certain industries that have embraced this more than others, and if there are any particular industries that would likely see a huge benefit that have been slow to embrace automaton.

Yes, amazing questions, listeners! Thanks so much!

thanks @Kelsey and @Stefan for a great lecture! 

Thank you all, hope you got some ideas out of it :)

@Stefan, thank you for the excellent lecture today!! Thanks also to our listeners for the spot-on questions!

@jgoodman Glad that made sense! (I haven't had my morning coffee yet, so I never know! Lol!)

Yes, Softbank is a good mix of virtual applications and network services. In the data-center we stitch security functions to the VPN, these functions are virtual applications.

@Stefan thanks very much for sharing these links

@Stefan, Thanks for sharing those links! Another listener question: What are some of the reconfigurations/tunings that almost always have to be completed for something to be production-ready?

From your prospective - what challenges will the service providers be prepared to handle in the examples shown; for example network traffic issues, routing protocol(s) support, MTU size, etc?

on Monitoring...It is very important to automate monitoring of the service as part of the service provisioning. I have presented thoughts on that "orchestrated assurance". Here are two links:


Thank You.  Great insight to help explain to  traditional IT  service architects  that a size fits all VM enrionment  for the network and services virtualization is really not practical. " when you have a hammer every problem looks like a nail."

Ah, it's just that the certificates are off.  Bypassed the security and got it, thanks.


@faryl thanks, that sounds plausible!

the state-convergence algorithm can restore the service bu calculating the diff from desired and render the config

@Jgoodman (that's just my personal two cents - I'm not an expert in that field though!)

automated trouble-shooting is a good one!

If you have a proper model of the services in the top-layer and the underpinning resources in the bottom layer, the automation tool can many times fix problems. More then 50% of service problems is wrong configs

@Jgoodman - I think that it's a risk to rely completely on automation for security - but by automating security testing, reporting, etc., you can cover more scenarios more effeciently to identify potential gaps & risks.

@Stefan: Is natural language processing generally very helpful in automation, the more sophisticated it gets?

4 pillars: https://www.lightreading.com/webinar.asp?webinar_id=541


@Phil, ping us via email at [email protected] with the link and we'll take a look

@Stefan: Listener question: 

Can automated troubleshooting scripts account for the vast number of possible subjective problems customers can have with their services?

Great presentation. Stefan is really visionary

Thank you Stefan for the great session!


thanks for the presentation


thanks!  great preso!


Great presentation! Thanks!

Great presentation. Thanks!

Thank you for the lecture Stefan!

Thank you for the session!

The 4 pillars of orchestration seminar link does not seem to work

What are the challenges (if any) with automating reporting and monitoring tools?

But doesn't totally automated security lead to greater risks??

Thank you very much Stefan! Good philosopie and useful insights.

Are tools such as Chef, TOSCA, Puppet, etc. an emerging market?  Do you anticipate seeing more players/options in that area?

@[email protected] Yes - we had several parallel environments... there were several QA certification stages to certify changes, to make it easier to identify which specific changes were the ones responsible for any bugs that may be introduced.

How many vendors support YANG.today.....? i think only a couple of them...so how can we have truly universal orchestrator

with customers being able to configure/change their networks more rapidly, what would be the impact on the network for "viral" service requests?

Thanks, great presentation and info. 

Thanks very much, Stefan

Thank you, Stefan! The slides were great to help illustrate what you were speaking about too. Very informative.

Is DevOpS mandatory for NFV operation ?

faryl so you had parallel environments

 But we timed our roll-outs of changes around off-market hours and made sure teams were available at market-open for a quick roll-back if something did end up breaking.

Stefan long term do you see sizable ROI on the automation projects you have worked on?

We didn't have any outtages when I worked there - so I guess it was successful! Lol! 

organization & cost of technology transformation

existing back office systems


Cost and Skill of Automation

Technology and Organization

What are the biggest barriers to increasing automation in your organization? Are those barriers related to technology, cost, time, or something else?

biggest barrior is the lack of training and awareness

time and cost (of time)

complexity of environment

Technology and organization

faryl i would expect you faced peak request times in that envronment --did you find the scripts modeled efficiently those types of peaks loads to avoid service issues?

@[email protected] When I worked doing QA at a "well known online trading company", we had a group that focused on automated test cases around load/servers.

(The rest of our testing was manual though!)

faryl have you been successful implementing that:)

Ah - so the data models make it more "plug & play" for the automation options?

[email protected] Good point! (I guess that's where automated load testing of the automation scripts comes in...automation to help automatation!)

I can see how automation could help in terms of services rebooted/restarted – I hadn't thought of that!

QUESTION: Is the "SoftBank" example in slide 15 an example of both application and network services being sold? (Email security as well as routing and VPN termination.)

faryl I would also expect possible performance issues if not tuned correctly?

It appears that it the automation needs highly customized tuning depending on solutions--is anyone doing this in house or relying on outsourcing?

@[email protected] True. I'm guessing the more granualar the options are, the more potential issues that arrise - depending on the sophistication of the end user.

@maryam it guided me to reset network connections in the house...before I called, I spent a bit of time trying to troubleshoot and could not resolve the issue. The robot on the other end of the phone helped me pretty efficiently. 

@faryl agreed, it makes maintainence much, much simpler. Amazon Web Services has autoscaling features that can create or shutdown instances based on workload and health checks.

Does the network centric apps do not need Devops ?

What are some of the reconfigurations/tunings that almost always have to be completed for something to be production-ready?

Maybe natural language processing is generally very helpful in automation, the more sophisticated it gets?

@cheungaryk Same here. The biggest benefit is being able to iniate having services rebooted/restarted as a first level trouble-shooting effort. I wish I could do that with the servers I have my websites hosted on instead of having to go through a help desk ticket each time.

Faryl probably also on how customized the automation is-- I would expect highly complex sollutions will be more challenging to support.

@faryl definitely. but this sounds like a general issue with automated troubleshooting scripts

@JGoodman I guess it depends on the nature of the problem and the competency of the customer? :-)

What are some of the best integrated virtualized cloud services on the market today?

I think the general question is whether automated troubleshooting scripts can account for the vast number of possible subjective problems customers can have with their services?

Those automated troubleshooting scripts (T-Mobile) are hit-or-miss for me - it worked for me a few times but sometimes, not helpful.

Good questions! What else would you all like to ask Stefan?

How does security integrate into the layers?

Troubleshooting options like AT&T Uverse can be really annoying - especially when customers are a bit more sophisticated.

@faryl doesn't this kind of automation lead to less ability for customers to overcome problems subjective to their own systems?

@FaisalKhan slides are under the educational materials!

Is this similar to the troubleshooting options AT&T Uverse offers now before having to interact directly with customer service? (It seems to allow the customer to launch automated troubleshooting scripts.)

what challenges do you see in implementation?

Cost savings...and I would imagine a reduction in errors, too

Main automation benefits are cost savings and improved customer perception/experience (e.g. time and reliabilty of service provisioning)

Automation helps to enhance productivity hence reduce cost.


I hear a lot about streamlined processes and provisioning when I'm talking to SPs

Streamlining management processes

Streamlined Product Management


Increased Automation will streamline Operations and improve Service Delivery.

Other - remove (reduce) the element of human error

automation will help in cost saving as it will result in a smart Operation org.


Streamlined processes. Faster TTM


increased security n reduced human errors 


biggest benefit to us: expand revenue via business growth


Buffering didn't help - I'm on firefox on OSX - will try Chrome instead & report back if it's better :-)

Can you talk more about self-healing tech? This sounds interesting, not familiar with it.

I've had problems using Chrome on Mac for these presentations, Firefox is a good option.

You do need established bussiness processes to fit into the new model

Using Chrome (on a Chromebook), no problem with sound.

Divert all power to communications.

Are there QA challenges specific to virtualization/automation?

Chrome is a good browser to use for the lectures

@shirleylong The sound keeps dropping out for me as well :-/

I'm going to try buffering and see if that helps (though it will put me a few seconds behind!)


Can automation also address the tasks specific to the customer´s business?

Greetings from San Diego!

How do IT administrator roles (like network administration, server administration, etc.) change as a result of automation?

@shirleylong mine cut out for a few seconds but started up again

Try refreshing  your screen, @shirleyong

I cannot hear the sound anymore. Is this just happening to me only?


can provisioning and deprovisioning be automated through lifecycle?

I'd like to understand some of the risks of automation.

We'll be asking a listener question shortly...what questions do you have for Stefan?

Greetings from Los Angeles, CA!

Looks like we have another global audience!

Listening from Mexico City and weather is pretty nice

These are excellent slides, by the way – lots of detail and the Softbank example is interesting.

Good afternoon everyone!  Remember to turn up your volume on the computers.  At the top of the hour an audio player will pop up on your screen.  If you don't see it, try to press F5 to refresh your screen. Remember, there's slides for this class posted above! We are looking forward to the discussion, so be sure to post your questions, comments and thoughts on the message boards and we will join you on the chat after the audio stream. 

In a world where security is paramount in IT because of the risks, are there opportunities to automate security? Or is it really not worth it?

Hello from South Africa!


plus is automation provisioning faster than cloud?


@DFPERSON & are automation tools scalable? ie if your enviro grows?

What tasks or processes are typically automated? 

and if automation is strictly a benefit to org's using complex confurations or is there a benefit if your config is simple or static?

Please download the slides in the link above so you can follow along with the presentation!

Would be interesting to hear what the automation impact is. Are people being moved into higher-value projects? Or something else?

@Hsweda - I was thinking the same thing!

wonder if he will discuss if organiztions who have automated have cut IT staff or redirected staff to other projects?

Hey everyone, looking forward to the presentation today!

Thanks.  looking forward to it...

Good to have you here, @hsweda and @dfperson!

Looking forward to Stefan's lecture!

Eating lunch now looking forward to the presentation.

Grab your sandwiches and salads and meet us back here in an hour for the LIVE course with Stefan! Don't forget to download his slides in the link above (see the "Special Educaitonal Materials" section).

Follow along with the lecture by downloading the slides in the link above, "Presentation: Virtualization - Automation."

Thanks for visiting early @Stefan! Looking forward to Friday's session. 

Looking forward to discuss this topic on Friday

@JohnGordon Lecture slides are coming soon, check back on Friday to download the slide deck.

Did I miss the link for the notes, or will this lecture not require them?

orchestration is a big hot button topic right now, isn't it, @hsweda? Has been for at least a year as service providers try to find the best way forward

Nice, cant wait to learn which orchestration tools are best for automation. 

Automation is  a key area in Virtualization so looking forward to this lecture from Carl.

I'm really looking forward to this one!

Carl is presenting on an excellent topic to round out this series on virtualization. 

Automation is a super hot topic these days -- especially when coupled with machine learning. Definitely looking forward to this lecture with Carl.
