Cloud computing is one of the emerging technologies that will lead to the next generation of Internet. It provides optimized and efficient computing through enhanced collaboration, agility, scalability, and availability. In this paper, the evolution of the Cloud is discussed, the cloud computing model is explained, a set of cloud computing infrastructure metrics is listed, the cloud service model...
Requests for services and user demands increase continuously and faster than technology development. In this way, we often cannot wait for faster hardware and devices (newer technologies); however, division of jobs between computers in network can improve the computing speed. In this article, we have considered computing elapsed time as criteria to design software at the software architecture level...
As applications grow more and more complex, the current software faces a great challenge in dynamism. This paper proposes to modernize legacy software towards runtime plug-and-play architecture using service-oriented component model. Our object is to provide runtime plug-and-play feature for software to simplify development and adapt to changing execution environment. We propose a two-stage modernization...
Autonomic systems received lately a great deal of interest from the research and industrial communities due to their ability to configure, optimize, heal and protect themselves with little to no human intervention. Such systems must be able to analyze themselves and their environment in order to determine how best they can achieve the high-level goals and policies given to them by system managers...
