Abstract:
Building a community cloud by federating private clouds is one of the lower cost alternatives for hosting applications that require distributed deployment to meet scale-saving, high availability, reliability, and service level compliance. Despite its potential benefits, there are many issues about lack of standardization, system integration, interoperability and portability across multiple service providers, resulting in low adherence to the model in organizations that are still struggling to adapt its legacy applications to a cloud architecture in complex environments, such as some governmental sector scenarios. Currently, there is no seamless approach to migrate from the traditional infrastructure model to a cloud computing model on these organizations. So, we propose an architecture for building a community cloud even in scenarios with a strong presence of non-cloud native applications by developing a low-coupled infrastructure middleware that supports different hypervisors, a GUI
and a CLI. To show the feasibility of our approach, we evaluate the architecture on a set of infrastructures at Superior Courts of Brazilian Judicial Branch, that may compose a cost-effective solution to start the transition to the cloud model in other organizations also.
