5. FP7-257993 Platform as a Service (PaaS) –vs. Infrastructure as a Service (IaaS) –Applications can be easily deployed into the platform Standard programming model (e.g., JEE) Multi-tier architecture –Highly scalable even with many updates (100+ nodes) –Highly available –Low response times / high throughput –Elastic: use only as many resources of the IaaS as needed –Providing full transactional properties Strong consistency required Cumulo Nimbo Goals (and Challenges) 5

6. FP7-257993 Fully transactional and scalable PaaS –End users are cloud application developers High performance communication and storage infrastructure. –The target users of this infrastructure are cloud providers. A business intelligence use case –For evaluation purposes –The target users are end users of business intelligence applications. Performance Evaluation and comparison with state-of-the Art –The target users are the scientific and industrial communities Promised Outcomes and their interest groups 6
