GaaS: Customized Grids in the Clouds

摘要

Cloud Computing has been widely adopted as a new paradigm for providing resources because of the advantages it brings to both users and providers. Even if it was firstly targeted at enterprises wishing to reduce their equipment management costs, it has been rapidly recognized as both an enabler for new applications and as a mean to allow enterprises of all sizes at running high demanding applications. Recently, Cloud Providers are trying to attract new applications, such as scientific ones, that today already benefit from distributed environment like Grids. This work presents a way to remove the paradigm mismatch between Cloud and Grid Computing, enabling the use of Cloud-provided resources with well-established Grid-like interfaces, avoiding the need for users to learn new resources access and use models. The proposed approach is validated through the development of a prototype implementation and its integration in a working Grid environment.
