Re: APIC equals SDN controller?
Or does it?
For months Cisco has been touting ACI as anything but SDN, in effect it was a highly reactive response to SDN in which they've come out the otherside incomplete and incoherent, just one of the reasons why the majority of network pro's will struggle with ACI concepts.
Unfortunately, there is a level of creative thinking the average network pro just doesn't possess, which is why the majority will probably rally behind NSX. Notwithstanding that networking vendors have been pandering more towards application developers over the past few years.
Overall I would not be compelled to pay for either, especially when you've got solutions like OpenContrail, Windows Server & System Center 2012 R2, which equates to very much the same thing, but for FREE!
