Re: NFV vs. SDN?
I've actually thought the same thing with SDN.  Why have your local IT staff make advanced configurations when you could potentially go to the source and have the vendor remote in for assistance.  Assuming you're not in an environment that requires the level of secrecy normally associated with military organizations.

Re: NFV vs. SDN?
Thanks for the link.  That article is probably the easiest to understand explanation that I have read so far. 

From a big picture point of view, it seems as though SDN & NFV are part of a longterm tug of war between software-centric solutions and hardware-centric solutions. 

Looking back at past examples such as software-based firewalls, VPN servers, etc.  It seems that hardware wins exept when the software version is so tightly integrated with other systems that it becomes the natural choice.

For example, in a Windows environment, DNS, DHCP, and print servers are typically configured as a windows server role, rather than relying on the perfectly functional native capabilities found in firewalls and printer firmware.

Re: NFV vs. SDN?
Well, first i'm just thinking that (since i'm just a student :) not  a specialist )

If NFV reaches all its objective, all vNFs will run on commodity hardware in datacenter. NFV will have features such as auto scaling and orchestration. So after the deployment of application, no human effort is needed  or at least not as in todays network. Also, if all operator uses NFV, who will needs hardware architect (expect intel and amd).

For jobs creation, all compagnies should migrate their solution to software, so they may hire new employees to help them.

Re: NFV vs. SDN?
Can you elaborate on how NFV will impact jobs? What kind of jobs will it create and what ones it will kill?

Re: NFV vs. SDN?
yes i'm referring to it, it's the organization behind the NFV,

they are working on it, but for example, SDN may see the light cause cloud operator could rebuilt datacenter from scratch, or new datacenter, but we can't simply replace the network infrastructure of a country..

also they provide only paperwhite, just concepts, or in the launch of SDN, there was many real implementation that's why it makes an impact...

I hope thay can make it, that will create many jobs :) and kill others

Re: NFV vs. SDN?
Are you referring to the European Telecommunications Standards Institute and the NFV standards I believe it's working on?

Re: NFV vs. SDN?
well, its marketing move : ).. but really for NFV as example, we see some real product such as OpenvSwitch that support openflow and some product of different startup around the world(north america and asia) , but for NFV, i don't really think the ETSI will make it.

Salaheddine, Your closing line makes me think you might be a fan of HBO's "Silicon Valley" ?

Re: NFV vs. SDN?
hey AbeG,

SDN is about virtualization of the network infrastructure, while NFV is about the virtualiztion of network function. NFV may run over SDN. each technology can be used separetely. However using them both will help create a better world :)
