In this paper we propose a new service delivery platform (SDP), named Future SDP that incorporates principles of cloud computing and service oriented architecture (SOA). Future SDP allows resources, services and middleware infrastructure deployed in diverse clouds to be delivered to users through a common cloud Broker. This cloud Broker is enhanced with policy, management, security and mediation functionalities that ensures proper use of development tools, resources and services only to certified participants of the federated clouds. This work focuses on solving interoperability problems both into infrastructure and middleware layer of the conventional SDPs. Finally, the operational attributes of Future SDP are depicted through a delivery scenario of healthcare telemonitoring services.
