Using proxies to facilitate collaboration in Multi-Cloud Computing Environments.

Abstract

As cloud computing becomes more predominant, the problem of scalability has become critical for cloud computing providers. For the client to be able to simultaneously use services from multiple clouds; individually interaction with each cloud service provider, gathering intermediate results, processing the collective data, and generating final results is necessary. Collaboration among multiple cloud-based services, like cloud mashups, opens up opportunities for Cloud service providers (CSP’s) to offer more-sophisticated services that will benefit clients. Today, cloud mashups need pre-established agreements among providers. This approach to building new collaborative services does not support agility, flexibility, and openness. This paper present the survey of the proxy-based multi-cloud computing framework which provides on the-fly, dynamic collaborations and cloud-based resource sharing services, addressing, policy trust, and privacy issues without pre-established collaboration agreements or standardized interfaces.
