The OMII software - Flexible for being a grid and a cloud

Abstract

Cloud Computing aims to provide scalable and inexpensive on-demand computing infrastructures with good quality of service (QoS) levels. More specifically, this involves a set of network-enabled services that can be accessed in a simple and pervasive way [1]. Currently Amazon EC2/S3, Windows Azure, Google Docs and Google Apps are leading commercial service providers. Open source cloud projects such as Nimbus, Eucalyptus, CloudSim and Aneka are offering incentives for pioneering cloud projects. There are attempts for re-prototyping Grid software as bespoke Cloud software, which include Globus and Nimbus. There is a particular project, OMII-UK software, which is started as a Grid but also in the process to be part of, or fulfil capabilities as a Cloud. To achieve this, we propose an OMII-UK Cloud Framework 1.0 to describe how OMII platform can be used as a Grid and a Cloud, particularly targeting for Platform as a Service (Paas) and Software as a Service (SaaS)
