Life cycle and characteristics of services in the world of cloud computing

Gerd Breiter; Michael Behrendt

The emerging style of cloud computing provides applications, data, and information technology resources as services of a network. The cloud services approach focuses on a positive user experience while shielding the user from the complexity of the underlying technology. Each cloud service progresses through a well-defined life cycle: The cloud service provider defines the cloud services to be offered and exposes them via a service catalog; service requesters instantiate the services, which are managed against a set of servicelevel agreements; and finally the cloud service is destroyed when it is no longer needed. This paper describes this life cycle and explains the relationship of managing the life cycle of cloud services to traditional ITILt (Information Technology Infrastructure Library) processes as they are present in many data centers today. Furthermore, this paper elaborates on ensembles that provide the hardware infrastructure required to optimally support such flexible and massively scalable cloud services. An ensemble is an autonomically managed pool of like resources that exposes only virtualized resources while hiding the physical infrastructure. This approach allows growing the physical infrastructure with very little or no incremental administration costs.

Cloud Computing — An Industry Perspective

Gerd Breiter; Thomas Spatzier; Michael Behrendt

Abstract Cloud computing is a new way in which IT is provided and consumed, enabling a gain in flexibility and cost-efficiency. In this paper, we give an industry perspective on cloud computing, discussing both consumer aspects as well as provider aspects that go along with that phenomenon. We present cloud computing as an evolutionary step based on advances in technology and economy, and in essence as the industrialization of IT. We will have a closer look at the concept of cloud services, including aspect like service templates, or service lifecycle, and we present an architecture enabling the efficient management of a cloud. Finally, we elaborate on aspects such as security and trust as well as standardization. Zusammenfassung Cloud Computing ist eine neue Art und Weise, IT flexibler und kosteneffizienter zu nutzen. In diesem Arikel betrachten wir Cloud Computing von Kunden- und Anbieterseite unter industriellen Gesichtspunkten als den nächsten Schritt in der Evolution von IT, bzw. der Industrialisierung von IT. Wir betrachten das Konzept von Cloud Services, Service Templates und deren Lebenszyklus und wir präsentieren eine Architektur zum effizienten Management von Clouds. Darüber hinaus betrachten wir Aspekte wie Sicherheit im Rahmen von Cloud Computing sowie Standardisierung.

Die weiteren Aussichten — wolkig!

ZusammenfassungCloud Computing und die Transformation des Rechenzentrums. In der heutigen globalisierten Welt müssen Unternehmen aller Bereiche sehr flexibel auf Veränderungen in ihrem Geschäftsumfeld reagieren können. Effektive und effiziente Unterstützung durch die entsprechenden IT-Services ist dabei von entscheidender Bedeutung. Doch diese Forderung zieht in vielen Fällen (r)evolutionäre Veränderungen im Rechenzentrum nach sich. Der technologische Fortschritt in den letzten Jahren hat viele fundamentale Änderungen im Geschäftsprozess und im Rechenzentrum möglich gemacht. Gleichzeitig hat jedoch die Komplexität in den Rechenzentren dramatisch zugenommen. Wie kann Cloud Computing dazu beitragen, mit diesen Herausforderungen umzugehen?
