GARCIA PERELLADA, Lilia Rosa  e  GAROFALO HERNANDEZ, Alain Abel. A Private Cloud's Reference Architecture Proposal. EAC [online]. 2015, vol.36, n.1, pp. 1-16. ISSN 1815-5928.

The Infrastructure as a Service model belonging to the Cloud Computing paradigm constitutes for most organizations a secure-cost-effective solution for rapidly achieving the computing infrastructure demand through dynamically scalable private data centers. The solutions proposed by leaders in the industry are generic architectures based on expensive hardware infrastructure of high-level computation, which may be inappropriate according to the real needs and constraints of the institution's Information and Communications Technologies. This hinders the adoption of this model in companies with strong economic constraints, so the goal of this investigation was to propose a Private Cloud Infrastructure supporting Infrastructure as a Service based on legacy hardware, or not, and Free and Open Source Software tools, with Quality of Service levels comparable to the commercial solutions levels. The results achieved were: a Reference Architecture that lets the design of Private Clouds that meet the objectives and constraints of the interested organizations; a deployment solution based on general purpose hardware and Free and Open Source Software. These results favorably impacts on the reduction of the organization's TIC´s investments.
