CloudAndVirtualNotes

Created Tuesday 03 October 2023

Also — "THE CLOUD"


There is no cloud, it's just somebody elses computer

A computer (possibly virtual), probably running Linux

Yep. Usually.

Funny, it's not talked about that much. Or enough.
Again, not the part that makes people Rich, or even popular

Why do we even use "cloud?"


After all, email is "cloud" and yet we never used that word.

Probably a B2B thing — this was the first time the SERVERS were freed from the bare metal


On Virtual

Many different ways to do "Virtual" and "Virtual-like," but roughly:

VIRTUALIZATION and CONTAINERIZATION

Pure Virtual

i.e. literally fake the whole computer. You have to install the OS, etc.


Containers

This is "Docker" et al:

You don't fake the whole computer;
you wrap up and "package" the stuff you need to use;
and try to wall it off from everything else.

When you get big, you have to think about this large scale

e.g. KVM
Kubernetes
and other tools for managing A BUNCH OF THESE.

Also, there's the Proton/Wine thing



But may be big in the future in terms of Linux killing windows;
given that games are usually the hardest thing to emulate.

more on containers later...
