This paper describes a novel architecture for supporting orchestrated distributed computing and other forms of dynamic communities that can benefit from on-demand access to processing and communications resources. This effectively provides a mechanism that allows network operators to sell communication and resource management services rather than `connections'. It offers a cost-effective solution, for example, for SMEs or other end users, who can delegate some backoffice processing to the operator. We show that this system is achievable by extending 21CN functionalities. The operator is no longer seen as simply providing infrastructure, but also generic services upon that infrastructure. A key feature of the approach is to capitalise on MPLS technology, enabling specific quality of service requirements to be accommodated. This communications infrastructure is used to support on-demand operations, coupling end users with resources owned by the network operator or third party providers. Furthermore, given the importance of security, the paper considers VPN-specific security issues.
