## Épuisement des ressources
|
||||
Apple a son iCloud, Adobe a son Creative Cloud, Orange son "Le Cloud", etc.
|
||||
OVH, hébergeur de site web, a même changé son nom pour devenir... OVHcloud.
|
||||
Les Échos avancent que 77% des entreprises ont au moins une application dans le cloud.
|
||||
Le cloud serait donc partout ?

## Redémarrage des VMs
|

En tout cas, dans l'enseignement supérieur, des cours de _cloud_ sont maintenant au programme.
|

Et me voilà donc devant des étudiants à parler ce dont tout le monde parle.
|
||||
Mais on parle de quoi au juste ?

|
||||
|
||||
#### Il n'y a rien à dire sur le _cloud_
|
||||
On commence par la base : le _cloud_ ce sont des ordinateurs. Beaucoup d'ordinateurs, allumés 24h/24. On les appelle des _serveurs_ et on les place dans des _datacenters_.
|
||||
D'ailleurs, les _serveurs_ et les _datacenters_ existaient bien avant l'invention du mot _cloud_.
|
||||
L'objectif de notre cours, c'est de comprendre comment, avec ces _serveurs_ on peut créer des Netflix, Google, Facebook, Twitter, Amazon, etc.
|
||||
C'est à dire des services qui ne tombent pas en panne, qui supportent des milliers (puis des millions et enfin des milliards) d'utilisateurs et qui ne coutent pas trop cher à maintenir.

||||
|
||||
#### Personne n'a besoin du _cloud_
