router/switch/server instances/VMs/ on the same platform. Is this
desirable?

How about hardware slicing support? such as switch, server and router

Re: CDN server log

[Djamel Sadok]

Hi Pete,

I do not use a CDN I am only interested in analyzing content popularity in
logs. These could be anonymized.

 Hi djamel.  If I understand your question - you should take a look at what
 sawmill offers. Many of our clients use this product to analyze our cdn
 produced logs.

  Good question Nick, what is a cloud switch? Is this like VSS in cisco

 The vss is virtual management software for a virtual switch.  This box
 looks like a piece of hardware that you can plug things into, so I'm
 just
 wondering what makes this a cloud switch and some other piece of kit not
 a
 cloud switch.
