Service Engineering: Entwicklung und Gestaltung innovativer Dienstleistungen
Die schnelle und effiziente Realisierung innovativer Dienstleistungen stellt zunehmend einen Erfolgsfaktor für die Wettbewerbsfähigkeit von Dienstleistungsunternehmen dar. Dienstleistungen werden in der Praxis jedoch oft "ad hoc", d. h. ohne systematische Vorgehensweise, entwickelt. Das Konzept des "Service Engineering" beschreibt Vorgehensweisen, Methoden und Werkzeugunterstützung für die systematische Planung, Entwicklung und Realisierung innovativer Dienstleistungen.

Eucalyptus is an open-source Cloud computing platform that attempts to clone AWS. It has realized functionalities similar to Amazon EC2, achieving flexible and practical Cloud computing with computing clusters and workstation clusters; it provides compatibility interfaces for EC2 and S3 systems. The applications that use these interfaces can interact directly with Eucalyptus, and it supports Xen [20] and KVM [21] virtualization technology, as well as Cloud management tools for system management and user account settlements.
High scalability: data allocation and computing task completion occurs in available computer clusters, and these clusters can be expanded to the scale of thousands of nodes easily. Big Data Technologies and Cloud Computing 37 3. High efficiency: data can be dynamically moved between nodes and the dynamic balance of each node is ensured, thus the processing speed is very fast. 4. High fault-tolerance: multiple copies of data can be saved automatically and failed tasks are reassigned automatically.
Use of local memory on every processing node to avoid disk I/O bottlenecks and to minimize latency. 4. Use of a decentralized, peer-to-peer architecture; all nodes provide the same functions and responsibilities with no central node to take special responsibility. This greatly simplifies deployment and maintenance. 5. Use of a pluggable architecture to keep the design as generic and customizable as possible. 6. A user-friendly design concept—that is, one that is easy to program and is flexible.
