These days everything is shifting to cloud computing. Two of the major types of clouds are infrastructure as a service (IAAS) & Platform as a service (PAAS) cloud. Network engineers and administrators make use of IAAS instead of physical hardware for implementing servers. Software Developers use PAAS for programming purposes. Virtualization is the main base for implementing cloud computing. The...

In this paper we present results from the deployment of F/OSS virtualization platform. This platform was used both for providing existing NDC’s services, in a production environment, and for developing additional new services using agile development methods. In greater detail, F/OSS virtualization was selected as the best solution in order to meet a number of different NDC’s requirements, these...

The cloud, which consists of data centers featuring a high concentration of CPUs and storage, is the natural habitat of the more popular Internet services, such as Facebook, Google Search, Google Drive, YouTube, etc. It is not limited to such large corporations: other companies can rent machines in the cloud to build innovative services. For example, Dropbox relies on Amazon Web Services to off...

Timing isolation is critical for automotive systems. Real-time virtualization, such as RT-Xen, is a promising technique to integrate legacy automotive systems onto a powerful multi-core platform for achieving better performance and lower cost without breaking the timing isolation. However, the real-time virtualization has never been evaluated with real automotive applications in a non-simulatio...

In the past decade the virtualization paradigm has been remarkably successful in the server domain, and significant benefits are expected from the virtualization of network resources. However, to date the virtualization capabilities of proprietary systems remain limited while the impact of executing open software routers within system virtualization platforms has not been fully investigated. In...
