Cloud Computing gewann in den letzten Jahren zunehmend an Bedeutung. Dies hatte zur Folge, dass immer mehr Cloud-Anbieter unterschiedliche Dienste in diesem Bereich anboten. Die Autorin Christine Affenzeller befasst sich mit dem aktuellen Stand dieser neumodernen Technologie und bietet einen strukturierten Überblick zur Definition, den Vor- und Nachteilen, den verschiedenen Modelltypen sowie den Sicherheitsmaßnahmen und Bedenken zu Cloud Computing. Anhand der Cloud-Systeme ‚Eucalyptus Open Source Cloud‘ und ‚Amazon EC2‘ wird die praktische Umsetzung dieser Technologie betrachtet. Im Speziellen steht hier auch das Verhalten von Web-Portalen in Clouds zur Diskussion. Letztlich wird mit Hilfe von Simulationstests die Belastbarkeit und Hochverfügbarkeit der Cloud-Systeme mit einer traditionellen physischen Server-Umgebung verglichen und auf mögliche Unterschiede untersucht.
