Java applications form an important class of applications running in the data center and in the cloud. They may perform better when more memory can be used in the heap, as the time spent in garbage collections is reduced. However, when ample CPU is available and memory is tight, such Java applications may do well with a smaller heap as it can absorb the cost of more garbage collections. In the cloud,...
The need to perform data analytics on exploding data volumes coupled with the rapidly changing workloads in cloud computing places great pressure on data-center servers. To improve hardware resource utilization across servers within a rack, we propose Direct Extension of On-chip Interconnects (DEOI), a high-performance and efficient architecture for remote resource access among server nodes. DEOI...
Software Defined Networks are being considered as very promising solution for data centers and cloud environment and are in the scope of interest of many research groups and service providers over the world. Various implementations of software defined networking are implemented and operate in data centers and wide area networks of global IT companies. In spite of SDNs are being developed and put into...
Cloud computing is based on virtualization, where a single physical resource is virtualized into multiple virtual resources. Processor and network virtualization offer many advantages like saving in hardware cost, energy consumption, human effort and management of resources. In this paper we have evaluated the effect of network and processor virtualization using popular open source tools, Open vSwitch...
The Special Session on “Pathways to Servers of the Future” outlines a new research program set up at Technische Universität Dresden addressing the increasing energy demand of global internet usage and the resulting ecological impact of it. The program pursues a novel holistic approach that considers hardware as well as software adaptivity to significantly increase energy efficiency, while suitably...
This paper presents a comprehensive system architecture, which adopts private cloud computing as the deployment model for consolidating IT services and data centers across different agencies within Taiwan Environmental Protection Administration (EPA). Through a number of well-planned procedures we integrates original 130 servers into 25 servers and merges 9 data centers into 2 data centers. The project...
The traditional IT industry and the mode of E-Government are currently experiencing great changes, Cloud Computing becomes a trend. This paper explains the definition and understanding of the Cloud Computing. Combined with the demands of the seismic system E-government, such as high performance computing, resource sharing service, building the green network, this paper analyzed the key technology...
Virtualization has fundamentally changed the data center network. The last hop of the network is no longer handled by a physical network switch, but rather is typically performed in software inside the server to switch among virtual machines hosted by that server. In this paper, we present the concept of a sNICh, which is a combination of a network interface card and switching accelerator for modern...
