Fault tolerance plays a vital role in ensuring high serviceability and reliability in cloud. A lot of research is currently under way to analyze how cloud can provide fault tolerance for an application. The work proposes a reactive fault tolerant technique that uses check pointing to tolerate the fault. The work proposes a VMμ Checkpoint framework to protect both VMs and applications in the VMs...

Web services, with an emphasis on open standards and flexibility, can provide benefits over existing capital markets’ integration practices. However, Web services must first meet certain technical requirements, including performance, security, and so on. Based on extensible markup language (XML), Web services inherit not only the advantages of XML, but its relatively poor performance, which mak...

Managing power and energy consumption has become a primary consideration for microprocessor design. This report examines the effect of technology scaling on static power and energy dissipation and evaluates three techniques to reduce static energy in primary and secondary microprocessor caches. We examine the energy and performance tradeoffs associated with each technique and present the leakag...

in the beginning of the 1980s, the organizational entrepreneurship was considered a factor which could affect the output of the small, medium and big organizations and improve the growth and innovation of an organization.  nowadays, large numbers of organizations exploit the entrepreneurship as a procedure to achieve long-term competitive advantages. thus, it is of great importance to identify ...

We address the seemingly implausible project of moving the technical support of complex organisational technologies online. We say ‘implausible’ because from the point of view of micro-sociological analysis and the influential work of Julian Orr (1996) there is a consensus that the diagnosis and resolution of technical failures is an intrinsically ‘localised affair’ (i.e., rooted within a speci...
