Mais ce service peut être considéré comme une offre de niche, car il ne reflète pas la stratégie de la société. En effet, on considère que la société est arrivée tardivement dans les services Cloud car elle a longtemps essayé de protéger son offre la plus rentable : les logiciels pour PC. Windows et Office sont en effet la « vache à lait » de Microsoft depuis presque 20 ans et il n’est pas dans l’intérêt de Microsoft que l’on utilise des solutions équivalentes dans le Cloud. Microsoft a donc longtemps résisté à la cannibalisation de son offre principale en refusant de proposer des services Cloud aux particuliers comme aux entreprises.

Lorsqu’on conserve plusieurs années d’e-mail, dans Outlook, le fonctionnement du logiciel ralentit, car l’exploration du disque dur lui prend de plus en plus de temps. On peut généraliser ce problème à Windows ou MacOS : plus l’ordinateur est ancien et saturé, plus son fonctionnement devient lent. Il est alors nécessaire de faire le ménage, de « défragmenter » pour regagner un peu de vélocité, sachant qu’on ne retrouvera jamais la rapidité initiale de l’appareil neuf. Ce problème n’existe pas avec le Cloud car les services Cloud sont bâtis différemment.

Il faut noter que certains acteurs du Cloud ne proposent pas la réversibilité, afin d’enfermer leurs utilisateurs dans leur outil. Il est donc conseillé de vérifier l’option de réversibilité avant d’utiliser un nouveau service Cloud. org). Ces employés ont poussé Google à être exemplaire sur ce sujet. Pourrais-je transmettre mes données ? La question de la transmission des biens numériques stockés dans le Cloud est un casse-tête. On peut envisager cette transmission dans divers cas de figure : je souhaite prêter un album musical ou un film acheté dans le Cloud, par exemple sur Apple iTunes, je souhaite donner ce même album musical ou film à un ami, je souhaite donner en héritage à mes enfants toutes mes données stockées dans le Cloud.
