Item Responsive Resource Scheduling in Cloud Environment(Department of Library and Information Science, Faculty of Social Sciences, University of Kelaniya, Sri Lanka, 2016) Ravindhren, V.G.; Ravimaran, S.Cloud computing has driven the IT industry to the next level in its evolution. Many IT companies provide subscription-based access to different types of Computing resources in the form of Infrastructure-as-a-Service (IaaS), Platform-as-a-Service (PaaS), and Software-as-a-Service (SaaS). Due to the rise of these services the cost of computation and application hosting has come down dramatically by several orders. But still there are challenges and complexity involved in the development of reliable and scalable applications in the dynamically changing cloud environment. One of challenging issues is to have efficient scheduling systems for cloud computing. Cloud computing resources being distributed across large geographical area makes it difficult to forecast the dynamic change of cloud environment in real-time. The Scheduling in Cloud environment is complicated further by the various QoS constraints such as: Optimization goals, choosing a scheduling algorithm for the nature of the task, system performance and cost. Most of the conventional resource allocation strategies are not suitable to handle the fast and dynamic nature of the Cloud Environment and may not satisfy the requirements of the clients. Therefore, this paper presents a new ResponsiveResource Scheduling framework which improves resource utilization as well asprovides cost effective solution. The core ideais to choose different scheduling algorithms for different situations. The result will demonstrate the suitability of the proposed scheme that will increase throughput, reduce waiting time, reduction in missed process considerably and balances load among the physical machines in a Data centre.Item Cloud Computing and its Applications in Library: A Review(Department of Library and Information Science, Faculty of Social Sciences, University of Kelaniya, Sri Lanka, 2016) Raja, S.; Krishnan, V.Cloud computing have not been a new technology that suddenly appeared on the web but it is a new form of computing. Cloud computing is a kind of computing technology which facilitates in sharing the resources and services over the internet rather than having these services and resources on local servers/ nodes or personal devices. Cloud computing is a kind of computing technology which facilitates in sharing the resources and services over the internet rather than having these services and resources on local servers/ nodes or personal devices. The combination of servers, networks, connection, applications and resources is defined as 'cloud'. Application of cloud computing user would be able to browse a physical shelf of books, CDs or DVDs or choose to take out an item or scan a bar code into his mobile device. All historical and rare documents would be scanned into a comprehensive, easily searchable database and would be accessible to any researcher. Many libraries already have online catalogues and share bibliographic data with OCLC. More frequent online catalogues are linked to consortium that share resources. The combination of servers, networks, connection, applications and resources is defined as 'cloud'. This article describes models of Cloud computing, applications in library, advantages, disadvantages of cloud computing in library and its barriers.Item Usage and Impact of Cloud Computing for Library Services(Department of Library and Information Science, Faculty of Social Sciences, University of Kelaniya, Sri Lanka, 2016) Bharanidharan, S.; Krishnamoorthy, G.Cloud Computing helps the people to share the resources and services in a distributed manner that belongs to various organizations via the network. Many organizations such as Google, Amazon etc.., develop cloud computing technologies to serve large number of users by enhancing the cloud based services. In the age of new information technology. Cloud computing plays a vital role in handling library services and resources for various activities such as storage, collection and processing of library information. New technologies and developments of new concepts are added newly to make ease of the library practices and to satisfy the needs of the people in the society. With the invention of cloud based technologies, the library activities are automated which is considered as a basic advancement and the efforts are moving forward to create virtual libraries. The advancement in digital technologies, usage of internet, and some of the web tools are introduced for library management. The most common cloud computing based library services includes Data (Bibliography, Technical), Content (Subscription, Digital Printing and Publishing) and Services (Content-access, research). Cloud based services like management of journal access, statistical information tracking etc.., are adopted for libraries. Since cloud computing is the new IT technology, the library professionals should be aware of these new technologies and should be trained to work with the library applications of cloud computing.Item Awareness and Usage of Cloud Computing Services (CCS) by members of the Library Staff: A Case Study on the Library of University of Kelaniya(Research Centre for Social Sciences, Faculty of Social Sciences, University of Kelaniya, Sri Lanka, 2016) Chamara, K.A.T.Today in this technical era, cloud computing is a very effective technology model for delivering Information Technology (IT) services. University libraries have started adopting Cloud Computing Services (CCS) for functioning the library in smoothly. The purpose of this paper is to identify the level of awareness and usage of CCS by members of Library in the University of Kelaniya. And also to identify the CCS they are using. A questionnaire and interviews were used for data collection. Questionnaires were distributed among all the members of Library staff except labourers. Most of the academic staff members of the library were aware of CCS and appeared to be using that knowledge for official and personal activities. However the use of this CCS by Non-academic staff members of the library was not at a satisfactory level. The findings revealed that staff members mostly use CCS such as mailing services, social networking services, video services, file sharing services for their activities. They only use WorldCat Cloud Library Service (CLS) for the library and most of them did not seems to know about other CLSs. It is observed that high rate awareness and advance computer literacy skills had led to high levels of usage of CCS. It is recommended that more awareness programmes and hands on trainings should be arranged for all the members of the library and at the same time Computer Literacy programmes are recommended for those members of the Non-academic staff who lack knowledge in computer literacy.
