In many regions of Europe, citizens and businesses are faced with the difficulty or impossibility of finding information and services provided by local public authorities on the internet. Any such information currently available is often segmented and isolated in a non-user friendly manner. The current project will facilitate access to information, public services and economic promotion by grouping online services in a unified portal following a user-centered logic . Federating services in a unique environment will enable public administrations to make better use of customer and businesses information and adapt public services (e-services) so they more often meet the needs of people and businesses. The result will be services that are more accessible, more user-friendly, more efficiently run by public authorities and less expensive for the taxpayer.The OASIS project will take advantage of open platforms and open standards using a cloud architecture. The Internet provides a reliable and trusted base for building applications and services. Cloud computing offers highly scalable databases for applications achieving great performances. Distributed data centers also provide fault tolerance against disasters, therefore improving the robustness of communications. Cloud distribution offer ubiquitous network access, location independent resources and rapid elasticity.The pilot will focus specifically on 12 applications for citizens, public authorities and businesses. The pilot will include user-enriched content from citizens/residents and will be accessible via internet, and smart phones with a telephone hotline and training sessions for support. The Pilot B of shared services will be demonstrated in 5 sites during 12 months.
