OW2 ProActive features the unique capacity to build Private Cloud (both in Native and Virtualized modes), together with dynamic bursting on all major Public Clouds. Overall, ProActive actually enables Cloud Brokering. Such an installation has been successfully achieved with ActiveEon’s customer SCP (Société du Canal de Provence). SCP mission is to develop and manage water resources, in order to provide a safe and reliable water supply for agriculture, industry and domestic use. SCP has strong credentials in over 40 countries in the fields of water development, management and engineering, as well as in operation and maintenance of hydraulic infrastructures. SCP uses ProActive and Azure Cloud to accelerate the IRMA application that simulate and compute settings for water distribution networks. ActiveEon made it possible to accelerate IRMA execution, to execute it on a private Cloud specifically built with ProActive over SCP internal resources (Windows and Unix OS), and to execute it as well on Microsoft Cloud, Windows Azure. With ActiveEon, SCP is able to execute IRMA runs that were lasting 3 full days, in only 30 minutes on Windows Azure. Moreover, all data and result transfers are included and automatically achieved in the figure above!
