3. Three “ranges” need to be addressed: 1.Immediately relevant topics: overcome the immediate barriers catch up with key players boost industry 2.Sustainability support issues: maintain the position by keeping up with progress create business value through advanced features 3.Paradigm shifters: overcome the long-term fundamental barriers create new business value by preparing for future market demand  All these types have different timescales  Must be initiated soon and mostly in parallel R&D Time Ranges (reminder) 1 2 3

4. 1.Data Management 2.Communication & Network 3.Resource description & usage 4.Resource management (Provider Support) 5.Multiple Tenants 6.Federation (& interoperability, portability) 7.Programmability & Usability 8.Political & Legislatory 9.Security 10.Business & Cost Models Main Research Topics

5. Managing data deluge Improved networking Improve the capabilities to exploit CLOUD features Improve the performance and portability of applications (Security) vulnerabilities Reducing vendor lock-in Comparability between offerings Viable business models / clear European benefit Immediately Relevant Topics

6. better understanding of the relationship between application and user / usage behaviour Means to use that relationship – this includes manage service discovery, (re-)composition and execution autonomically allow developers to produce quickly and cheaply well-designed software identification and provisioning of typical CLOUD usage patterns (cf. HADOOP) Deal better with the growing heterogeneity Paving the way for personalised service provisioning and usage Extended outsourcing and composition of capabilities Scalable orchestration of services and virtualised resources Maintain / improve trust through Enhanced protection Address privacy concerns Sustainability R&D Topics

7. New paradigms to address the underlying challenges and ‘leapfrog’ the competition Dynamic (re-)composition of services; intelligent networking; cross-platform service deployment Big data managing integrity (state) and heterogeneity of data models. declarative programming with execute-time data binding – for flexibility, heterogeneity, consistency etc. interoperation and federation (heterogeneity and mobility) - appear to the application environment as one uniform platform. Exploitation of new device types and environments advances in hardware for processors, storage, detectors and instruments and networks – along with associated low-level (embedded) software Paradigm Shifters

8. And the response

9. Major Objective To deliver an open and integrated platform to support both design and deployment of Cloud applications, together with an accompanying methodology that allows model-based development, configuration, optimisation, and deployment of existing and new applications independently of the existing underlying Cloud infrastructures.
