This paper presents results of the ongoing development of the CYCLONE as a platform for scientific applications in heterogeneous multi-cloud/multi-provider environment. The paper explains the general use case that provides a general motivation for the CYCLONE architecture and provides detailed analysis of the bioinformatics use cases that define specific requirements to the CYCLONE infrastructure components. Special attention is given to the federated access control and security infrastructure that must provide consistent security and data protection for distributed bioinformatics data processing infrastructure and distributed cross-organisations collaborating teams of scientists. The paper provides information about selected use cases implementation using SlipStream cloud automation and management platform with application recipe example. The paper also addresses requirements for providing dedicated intercloud network infrastructure which is currently not addressed by cloud providers (both public and scientific/community).

Various Cloud layers have to work in concert in order to manage and deploy complex multi-cloud applications, executing sophisticated workflows for Cloud resource deployment, activation, adjustment, interaction, and monitoring. While there are ample solutions for managing individual Cloud aspects (e.g. network controllers, deployment tools, and application security software), there are no well-integrated suites for managing an entire multi cloud environment with multiple providers and deployment models. This paper presents the CYCLONE architecture that integrates a number of existing solutions to create an open, unified, holistic Cloud management platform for multicloud applications, tailored to the needs of research organizations and SMEs. It discusses major challenges in providing a network and security infrastructure for the Intercloud and concludes with the demonstration how the architecture is implemented in a real life bioinformatics use case.

Multi-cloud applications delivered across heterogeneous public cloud service providers poses different technical and operational challenges in terms of resource brokering, integration, implementation of security trusts, etc. In this paper we describe the federation approach taken in the H2020 CYCLONE project, which designed a multi-cloud platform integrating and orchestrating different open-source cloud and network management tools (Openstack, OpenNaaS, SlipStream and TCTP). Some real-life use-cases in the scientific area of energy optimization and bioinformatics are in use to validate the CYCLONE architecture and integrated platform, from the viewpoints of service deployment, service availability, elasticity and security. These validation activities are carried out in the CYCLONE shared testbed infrastructure, whose high-level description is also presented in this paper. Initial feedbacks on the validation of the CYCLONE federation approach will be available at the beginning of Q4-2016, when the CYCLONE usecase portfolio will be extended to increase external users' involvement and attempt validation of the federation approach from real world market
