This time is referred to as a strategic inflection point. Adopting new technology or fighting the competition may not be enough when these critical moments arise. That’s because inflection points build up force so quickly that organizations may have a hard time even putting a finger on what has changed. The way a firm responds could propel it to new heights or lead to its demise. Over the last few years, industry has begun developing a model of information technology known as Cloud computing, which includes Software as a Service. This new model has reached an inflection point and will give users the choice to purchase IT as a service, as a complement to, or as a replacement of the traditio.“

Software as a Service
Software as a Service (SaaS) ist die oberste und letzte Schicht des Cloud Computing Service-Models. Sie stellt dem Anwender vollständige Anwendungen zur Verfügung. Sie kann als eine Art Distributionsmodell verstanden werden, bei dem die Nutzung von Software (Lizenzen) über das Internet von einem Drittanbieter angeboten wird. Der Drittanbieter übernimmt dabei u.a. die Wartung/ Aktualisierung und das Hosting der Software. Für den Anbieter besteht der Vorteil darin, dass nur eine Instanz einer Software auf den Servern bereitgestellt werden muss, welche unzählige Anwender gleichzeitig nutzen können. Wird die Software auf einen aktuellen Stand gebracht, genügt ein Update Vorgang an zentraler Stelle und die Software ist für alle Anwender gleichzeitig aktuallisiert. Der Vorteil für den Anwender besteht darin, dass lediglich – wie schon bei PaaS – nur ein Desktop-PC, ein Web-Browser und eine Internetverbindung ausreicht um z.B. Dienste wie E-Mail, Office Anwendungen oder sogar ERP-Systeme nutzen zu können. Die Anschaffung und Wartung großer Serverlandschaften bzw. Softwarepakete entfällt ebenso wie das ‚lästige‘ Updaten der lokalen Anwendungen. Der Drittanbieter sorgt immer für einen aktuellen Stand der Software und stellt die gesamte Infrastruktur für das Hosting der Software bereit. Dazu gehören auch das Speichern von Dateien (Dokumenten) auf den Servern des Anbieters. Der Anbieter ist demnach für alle notwendigen Bereiche des Betriebs, wie Verfügbarkeit, Backup, Redundanzen und auch die Stromversorgung verantwortlich. Auch hier erfolgt die Abrechnung wieder mit pay per use, mit dem kleinen Unterschied, dass die Kosten pro nutzenden Anwender der Software berechnet werden.
