API scripts: CML and Vsphere

In the last months I have been trying to practice the knowledge from CCNA DevNet and managed to wrote very basic scripts using API.

CML is a simulation solution from Cisco that actually works (you have to pay and need hardware). There are nice docs out there:

CML sandbox

CML Starting guide + API examples (this saved me)

CML simulation lifecycle example (havent tried yet)

CML: I actually struggled in this one regarding how to authenticate….. Checking some pages I worked out. I was trying to use the theory from DevNet but no joy. The idea is to restore a lab after you have made many changes. The script log into CML, delete the lab and restore with a provided backup.

Some docs for vsphere api:

Vsphere create session: (quite useful)

vcenter REST API authentication

vcenter API with Postman

Vsphere postman examples (need to take a look)

Vsphere: This is even simpler…. at least in this one I didnt struggle with the auth as the documentation was quite clear. But the original goal of restore a VM from a snapshot looks like is not available via API.

I guess this is a bit old news already. But I wanted to test it for some weeks. I have just made one question so far (and it failed a couple of times until I got an answer.

And my very first question was to list the most famous quotes from Aristotle to his actual writings. Why? Because you read many quotes from many famous people that are not actually true and it is very hard to really track if you dont read all books from that person. And to be honest, philosophy is not easy to digest. 

Here are a few famous quotes from Aristotle that reference his actual writings:

"Happiness is the meaning and the purpose of life, the whole aim and end of human existence." - Nicomachean Ethics

"It is the mark of an educated mind to be able to entertain a thought without accepting it." - Metaphysics

"We are what we repeatedly do. Excellence, then, is not an act, but a habit." - Nicomachean Ethics

"The whole is greater than the sum of its parts." - Metaphysics

"Nature does nothing in vain." - Politics

Please note that these quotes should not be taken as direct verbatim from Aristotle's work but rather as a representation of his thoughts.

Apart from that, I wonder how is the infrastructure of this company? Is on premise or cloud? How is their DC network design? TCP? Checking one of the open positions it seems they have a pretty big cluster. Although they mention cloud platforms. And the company has some kind of agreement with MS (so Azure is going to be used)
