Quality of Services in Cloud Collaboration

Abstract

Today ,cloud collaboration become an integral part of large scale of applications ,which describes how can multiple domains like cloud and users collaboratly share their knowledge ,information ,documents, files at virtual location. Collaboration is also important because it reduce the communication cost of various large scale business applications like, e-commerce websites, online education system . Sharing, coauthoring are its important characteristics. QOS that is quality of service in cloud collaboration act as a monitor of services with respect to the cloud integrated with user domain. Quality of service parameters like performance, bandwidth, throughput, response time of services affect the cloud collaboration in greater extent .QOS, are used to satisfy the user domain for their requested services, if requested service are not reliable or satisfactory then they are not use by the user again which degrade the service performance for user utilization . Collaboration factor is secure if used services in clouds are also secure and reliable. Significant importance of QOS are to increase the robustness, availability , reliability, reduced response time of a services .Cloud collaboration use uploading services, editing services ,sharing services. Cloud-based systems are gaining enormous popularity due to a number of promised benefits, including ease of use in terms of deployment, administration and maintenance, high scalability as well as flexibility to create new services. The growing presence of cloud-based services creates new problems for users and resource share domain, results in a number of challenges that need to be addressed in order to ensure successful adoption of new paradigm. Besides well known and frequently raised issues of privacy and security, a major problem the cloud collaboration technique faces is about the quality experienced by those who using coud services.
