What is NFVi?
For many years at Ericsson, we made SW and HW very dependent on each other. Customers bought whole racks of custom HW and the Ericsson SW applications deployed and running on top of that HW.
- NFVi is part of the NFV framework and it means, more or less, decoupling the SW from HW for network nodes using virtualization.
- It means you can run the telecom applications(the SW) on any HW (like Dell, HP, Qanta, SuperMicro, Fujitsu servers, whatnot), in VMs or containers.
- Basically, you can run it on Intel HW, 'cause that's so much better ... meltdown ... spectre ... zombieload

Traces of this decoupling of the network functions from proprietary hardware have been there for many years now.
Around 2003, I worked in an ISP. We used Cisco routers to do BGP with customers and the upstream provider. I was in awe when GNU Zebra came out and I could run BGP in a Linux box.

- In 2001 my first job was sysadmin working for a big Eastern European Internet Service Provider
- Many customers asked to move their web servers and mail servers on our premises.
- It was because their services would access directly the big pipe and we had a generator. 2001 Eastern Europe meant lots of power outages ... daily.
- They would bring desktop tower PCs that we would place on and under lined up tables against the wall. Soon enough, we ran out of physical space on those tables and bought racks.
- We asked customers to buy rackable servers in order to host with us, then we ran out of space again, we build an awesome datacenter and somewhere 2005 we ran out of space there too. We started using VMs with kvm.
- Fast forward, today our datacenters are collections of those stacked boxes that used to be desktop computers. To me, this is insane, does it make any sense to you? Should we go down the timeline of computer history and disagragate it all and have racks of compute, memory, storage, networking?

+ 1. Moral rights, such as the right of integrity, are not
+ licensed under this Public License, nor are publicity,
+ privacy, and/or other similar personality rights; however, to
+ the extent possible, the Licensor waives and/or agrees not to

+
+ 2. You may satisfy the conditions in Section 3(a)(1) in any
+ reasonable manner based on the medium, means, and context in

+ c. You must comply with the conditions in Section 3(a) if You Share
+ all or a substantial portion of the contents of the database.
+
+For the avoidance of doubt, this Section 4 supplements and does not
+replace Your obligations under this Public License where the Licensed
+Rights include other Copyright and Similar Rights.
+
+
+Section 5 -- Disclaimer of Warranties and Limitation of Liability.
+
+ a. UNLESS OTHERWISE SEPARATELY UNDERTAKEN BY THE LICENSOR, TO THE
+ EXTENT POSSIBLE, THE LICENSOR OFFERS THE LICENSED MATERIAL AS-IS

+ ACCURACY, OR THE PRESENCE OR ABSENCE OF ERRORS, WHETHER OR NOT
+ KNOWN OR DISCOVERABLE. WHERE DISCLAIMERS OF WARRANTIES ARE NOT
+ ALLOWED IN FULL OR IN PART, THIS DISCLAIMER MAY NOT APPLY TO YOU.
+

+ ADVISED OF THE POSSIBILITY OF SUCH LOSSES, COSTS, EXPENSES, OR

+ IN PART, THIS LIMITATION MAY NOT APPLY TO YOU.
+
+ c. The disclaimer of warranties and limitation of liability provided
+ above shall be interpreted in a manner that, to the extent
+ possible, most closely approximates an absolute disclaimer and
+ waiver of all liability.
+
+
+Section 6 -- Term and Termination.
+
+ a. This Public License applies for the term of the Copyright and
+ Similar Rights licensed here. However, if You fail to comply with
+ this Public License, then Your rights under this Public License
+ terminate automatically.
+
+ b. Where Your right to use the Licensed Material has terminated under

+
+ 1. automatically as of the date the violation is cured, provided
+ it is cured within 30 days of Your discovery of the

+ c. For the avoidance of doubt, the Licensor may also offer the
+ Licensed Material under separate terms or conditions or stop
+ distributing the Licensed Material at any time; however, doing so

+ conditions.
+
+ c. No term or condition of this Public License will be waived and no
+ failure to comply consented to unless expressly agreed to by the

+# `bin`
+
+This directory contains scripts that sometimes come in handy doing
+presentations.
+
+## `screen.sh`
+
+This is a wrapper around the Linux `script` command that invokes
+`screen -xR` (which spawns a new `screen`, or connects to an existing
+`screen` session if one is running).
+
+This script requires the `script` and `mktemp` commands, which should
+be available for any contemporary distribution as installable packages
+— if they're not already installed by default.
+
+## `shellinabox.sh`
+
+This is another wrapper script that also starts `screen`, attaching to
+the same session as previously created by the `screen.sh` script, and
+exposes the terminal as a small embedded web server at
+ . You are then able to add this terminal to
+your screen, for the purpose of doing a live demo or anything else you
+might need a terminal for. To do so, simply include an inline frame in
+one of your slides, like so:
+
+```html
+
+```
+
+Alternatively, you can also include the terminal as a slide
+background, which has the added advantage that you can easily
+configure it to fill the full available screen.
+
+```html
+
+```
+
+## `demo.sh`
+
+If you're using the `data-background-iframe` option in your slides,
+you will not be able to type into your screen session from within the
+presentation. However, with the `demo.sh` script you can still include
+a terminal demo easily:
+
+- Ahead of your presentation, start `screen.sh` and `shellinabox.sh`.
+
+- In addition, start `demo.sh`. This will simply create yet another
+ connection to the same `screen` session.
+
+- Start your presentation. Hit `s` for the speaker console, then pull
+ your main window to your projector screen — be sure to put
+ your browser into full-screen mode —, and leave the speaker
+ console (and your terminal application) on your laptop display.
+
+- When you get to your demo slide, use `Alt-Tab` to switch to the
+ terminal, and type from there. Your typing will be displayed nicely,
+ and in full width, on the projector screen.
+
+- When your demo is complete, use `Alt-Tab` again to switch back to
+ the speaker console, and continue advancing through your slides.
+
+
+## `asciinema.sh`
+
+If you are making your slides available after your presentation, you
+may want to include a screencast of your demo. To turn your recorded
+`script` into an asciicast, simply run `asciinema.sh`. It uses
+`scriptreplay` to play back your demo, and then uploads it to
+[asciinema.org](http://www.asciinema.org).
