Cloud computing, the concept where resources are provided as a service over the Internet, has gained fertile ground by avoiding the need for upfront investment in capital investment. One of the main goals of RESERVOIR has been to enable smaller infrastructure providers to collaborate through the federation of their resources on demand. A European RESERVOIR Cloud provider can transparently extend its capacity by connecting over the Internet to another RESERVOIR Cloud provider with the capacity to habdle a higher volume of service requests.

Reducing costs for ICT

A major benefit of Cloud computing is that service providers pay for the amount of resources they actually consume. RESERVOIR has taken this a step further by allowing for automatic allocation and deployment of resources to a service as demand fluctuates. Using a concept called elasticity, RESERVOIR allows service providers the ability to define both an initial and maximum allocation of resources. RESERVOIR then automatically monitors the service performance that it is running, increasing or decreasing allocated resources behind the scenes to minimize costs. This allows for a greater utilization of physical resources in the Cloud, which translates into lower costs both for infrastructure and service providers, and, most importantly to the consumer.

RESERVOIR (Resources and Services Virtualization without Barriers) is a European Union FP7 project that has enabled massive scale deployment and management of complex IT services across different administrative domains, IT platforms and geographies. The project has provided a foundation for a service-based online economy, where – using virtualization technologies – resources and services are transparently provisioned and managed on an on-demand basis at competitive costs with high quality of service.

The combination of open standards and open source software is part of the return on investment of RESERVOIR’s contribution to the economic and scientific development within the European Union.
