ATMOSPHERE (Adaptive, Trustworthy, Manageable, Orchestrated, Secure Privacy-assuring Hybrid, Ecosystem for REsilient Cloud Computing) is a 24-month project aiming at the design and development of an ecosystem of a framework, platform and application of next generation trustworthy cloud services on top of an intercontinental hybrid and federated
resource pool. The framework considers a broad spectrum of properties and their measures.
The platform supports the building, deployment, measuring and evolution of trustworthy cloud resources, data networks and data services. The platform is demonstrated on a sensitive
scenario to build a cloud-enabled secure and trustworthy application related to distributed telemedicine. This report belongs to WP6, which is the WP responsible for going beyond the state of the art in developing Trustworthy Data Processing Services (TDPS). Specifically, this deliverable is a report on principles and practices that should be integrated in the development process of TDPSs, from early design phase, to the development, integration, and testing of these services. The concept of trustworthiness is presented in detail in this deliverable, taking into consideration all the issues and challenges someone has to overcome when designing and providing trustworthy data intensive cloud services. This work is the outcome of literature review, and also of an aggregation of work carried out in relevant ATMOSPHERE WPs, and their main findings so far.
Service design principles are presented, after examining all desirable properties such as Privacy, Security, Fairness and Transparency (PSFT) and reviewing appropriate
frameworks/architectural approaches, like the Lemonade platform [LEMONADE17]. Once developers have at their disposal all the necessary tools, metrics, and mechanisms for developing Trustworthy Data Processing Services, the best practices provided in this report will help them with a warm start towards providing data intensive apps with PSFT guarantees.
