Sample text

L’application Cloud que nous utilisons peut se trouver San Francisco, Paris ou Pékin : cela fait finalement peu de différence pour nous. Le mot « nuage » fait principalement référence à cette abstraction sur la localisation. La métaphore est la suivante : les vrais nuages se déplacent perpétuellement autour de la terre, on ne sait pas les localiser ; il en est de même du Cloud pour lequel la position géographique des données est inconnue. Certains acteurs du monde du Cloud jouent d’ailleurs sur cette abstraction : ainsi Google entretient un certain mystère autour de l’emplacement de ses centres de données.

Google propose aussi une plateforme technique destinée aux informaticiens : Google Cloud Platform. Elle permet de créer des sites et des applications web réalisés par programmation. Pour terminer la présentation de Google, on peut citer quelques projets futuristes de la société : Google Car, une voiture qui se conduit toute seule, et qui commence à rouler sur les routes Californiennes (voir chapitre 7) ; Google Project Glass, des lunettes qui projettent des informations sur leurs verres, comme des e-mails ou le chemin à suivre pour attendre une destination (voir chapitre 9).

Pour éviter ce syndrome du « Big Brother », certains choisissent donc d’utiliser des services en ligne issus de nombreux acteurs du Cloud et d’avoir une identité séparée pour chaque service en ligne. Ainsi, le fournisseur de service de photo en ligne différera de celui d’e-mail, de celui de messagerie instantanée, etc. Ces tenants de l’anonymat se créent parfois plusieurs comptes sur le même service (ex : Gmail ou Twitter) afin de se présenter sous divers traits de leur personnalité selon les contextes.
