    Internet Cloud Architectures

    In the area of Internet cloud architectures, we work on national and international projects with different focus. In the following, projects are listed and results are presented.

    Das Team um Florian Wamser, Frank Loh, Roberto Bruschi, Paolo Lago, Michael Seufert und Phuoc Tran-Gia hat mit der Demo "Dynamic Cloud Service Placement for Live Video Streaming with a Remote-Controlled Drone" den Best Demonstration Award des IFIP/IEEE International Symposium on Integrated Network Management 2017 (IM) in Lissabon gewonnen. Die Demonstration zeigt wie durch Migration von Clouddiensten in Edge Cloud-Netzwerken die Quality of Experience (QoE) beim Fernsteuern einer Drohne verbessert werden kann. Sie wurde im INPUT Projekt zusammen mit den Partnern vom Consorzio Nazionale Interuniversitario per le Telecomunicazioni (CNIT) an der Universität Genua vorbereitet.

    Current Projects

    INPUT (In-Network Programmability for Next-Generation Personal Cloud Service Support, funded by European Commission H2020)

    The goal of INPUT is to design a novel edge cloud supported infrastructure for personal cloud services. Within this project, our focus is mainly on monitoring, orchestration, and consolidation algorithms for optimized configuration of network/cloud infrastructure and allocation of virtualized cloud services with respect to energy consumption and Quality of Experience.

    DFG QoE-DZ (Analysis and Optimization of the Trade-off between QoE and Energy-Efficiency in Data Centers)

    This project focuses on quantifying and adjusting the trade-off between QoE and energy-efficiency in data centers for highly relevant use cases. An interesting use case for the interconnection between data centers, QoE, and energy-efficiency that is considered to have an increasing impact in the following years, are Virtual Desktop Infrastructures (VDIs). A VDI enables users to use very lightweight systems, e.g., so-called thin clients, whereby the actual operating system including all computations and software runs in a data center.
