Cloud providing on demand storage services enforcing techno commercial service level agreement for an improved QoS

摘要

Advancements in the application service provisioning have created stringent scenarios in the world of cloud. The framework now needs to comply with specific requirements of consumers with specific demands. The diversified needs of storage and other related services in the dynamically changing needs of consumers. Such application requirements are becoming frequent as a consequence to high performance computing and large data/information retrievals. At the same time, understandings between the Cloud and its consumers have to be more transparent and should work under pre-defined terms. This leads to a committed Quality of Service delivered which directly effects revenues. To bring in transparency and durability between the service providers and service seekers, there is a need of a Techno Commercial Service Level Agreement that fixes responsibility of both parties. In this work, authors propose and implement an algorithm for meta scheduling that envisages enforcement of SLA apart from managing the distinct cloud applications such as storage. The work assesses the changes brought in terms of revenues, QoS enhancement, recoveries, building long term ties etc. The results have been found to be encouraging while testing the scheduler proposed with stringent service level conditions well. The agreement imposes clear by laws and penalties to the bi-part irate redressed on service provider cloud & the consumers. The frame work is tested and achieves objectives & goals with specific features suitable for storage cloud.
