Energy-Efficient Virtual Machine Consolidation
Found in: IT Professional
By Pablo Graubner,Matthias Schmidt,Bernd Freisleben
Issue Date:March 2013
pp. 28-34
A novel approach to virtual machine (VM) consolidation, based on energy-efficient storage migration and live VM migration, is implemented using Eucalyptus, an open source clone of the Amazon Elastic Compute Cloud. Several experiments demonstrate the potent...
 
Checking Running and Dormant Virtual Machines for the Necessity of Security Updates in Cloud Environments
Found in: Cloud Computing Technology and Science, IEEE International Conference on
By Roland Schwarzkopf,Matthias Schmidt,Christian Strack,Bernd Freisleben
Issue Date:December 2011
pp. 239-246
A common approach in Infrastructure-as-a-Service Clouds or virtualized Grid computing is to provide virtual machines to customers to execute their software remotely. While giving full super user permissions eases the installation and use of a customer's so...
 
Energy-Efficient Management of Virtual Machines in Eucalyptus
Found in: Cloud Computing, IEEE International Conference on
By Pablo Graubner,Matthias Schmidt,Bernd Freisleben
Issue Date:July 2011
pp. 243-250
In this paper, an approach for improving the energy efficiency of infrastructure-as-a-service clouds is presented. The approach is based on performing live migrations of virtual machines to save energy. In contrast to related work, the energy costs of live...
 
Efficient Storage Synchronization for Live Migration in Cloud Infrastructures
Found in: 19th Euromicro International Conference on Parallel, Distributed and Network-Based Processing (PDP 2011)
By Katharina Haselhorst,Matthias Schmidt,Roland Schwarzkopf,Niels Fallenbeck,Bernd Freisleben
Issue Date:February 2011
pp. 511-518
Live migration of virtual machines is an important issue in Cloud computing environments: when physical hosts are overloaded, some or all virtual machines can be moved to a less loaded host. Live migration poses additional challenges when virtual machines ...
 
TrustBox: A Security Architecture for Preventing Data Breaches
Found in: 19th Euromicro International Conference on Parallel, Distributed and Network-Based Processing (PDP 2011)
By Matthias Schmidt,Sascha Fahl,Roland Schwarzkopf,Bernd Freisleben
Issue Date:February 2011
pp. 635-639
In this paper, a novel approach to prevent accidental or deliberate data breaches is presented. The proposed approach provides platform, network and offline security. Data is categorized as sensitive or insensitive, and the corresponding applications are i...
 
Efficient Distribution of Virtual Machines for Cloud Computing
Found in: Parallel, Distributed, and Network-Based Processing, Euromicro Conference on
By Matthias Schmidt, Niels Fallenbeck, Matthew Smith, Bernd Freisleben
Issue Date:February 2010
pp. 567-574
The commercial success of Cloud computing and recent developments in Grid computing have brought platform virtualization technology into the field of high performance computing. Virtualization offers both more flexibility and security through custom user i...
