Integration of CLEVER clouds with third party software systems through a REST web service interface

摘要

Nowadays, a typical scenario in the panorama of cloud computing includes an IaaS cloud provider offering on-demand VM hosting services to its clients. In this field, famous examples of large scale commercial providers are Amazon and Rackspace. However, how to arrange analogous providers with open source tools is not totally clear. Moreover, the integration between an IaaS cloud middleware with third party legacy software systems, today, represents a difficult task to accomplish. CLEVER is an open source cloud IaaS middleware allowing the allocation and management of VMs. In this paper, through the development of a REST interface, we discuss how a CLEVER-based cloud provider can be integrated with third party systems, hence satisfying their VM allocation requests.
