- 1. A Reflective Platform for Highly Adaptable Multi-Cloud Systems Philippe Merle, Romain Rouvoy, Lionel Seinturier Inria & U. of Lille, France ARM Workshop 2011 http://frascati.ow2.org http://adam.lille.inria.fr
- 2. A wonderful world with Cloud Computing
- 3. A phethora of heterogeneous clouds
- 4. Clouds are complex phenomenons
- 5. Major issues for Cloud Computing 2.0 Multi -Cloud portability How to build service-oriented applications portable on different cloud platforms Inter -Cloud distribution How to provision service-oriented applications distributed across different cloud platforms Migration, brokering, geo-diversity
- 6. Service Component Architecture (SCA) Technology- agnotic OASIS standard component-based programming model for SOA Network Network Sec. Trans. log

- 15. Lessons learnt The experiment works! Heterogeneous IaaS/PaaS management SaaS portability FraSCAti both as a SaaS or a PaaS support for heterogeneity Reconfiguration vs security
- 16. Lessons learnt (2) Adaptation @ design time 22 out of 62 plugin/module/feature used FraSCAti as a SPL Towards a principled SPL for IaaS/PaaS/SaaS? Adaptation @ run time Low level REST reconfiguration API DSL FraSCAti script Scenario such as: adding peers, etc. Towards a feature-based reconfiguration DSL?

Editor's Notes
- #6: Migration, brokering, geo-diversity Avoid vendor lock-in syndrome, princing strategy, power consumption (small data centers consumes less)
- #16: When embed as a SaaS layer in another PaaS, the extra layer of indirection remains compatible with the scalability requirements for multi-cloud scenario
- #18: ComplexArchitectureDescription addresses a designchallenge related to the description of SaaS that spawns billions of nodes Consistent Software Configuration refers to the exploration of approaches, such as software product lines (SPL), … soft- ware development kit (SDK), libraries (e.g., Java), operating system, or resources (memory, processor, etc.), Continuous Service Delivery refers to the scalable and dynamic brokering and deployment of a system across a cloud of clouds. This challenge exhibits the need for an abstraction that federates existing clouds as an open infrastructure used to deploy SaaS Autonomous Management … reliability and the optimization of the infrastructure, … pricing variations of a given Cloud solution, and consider alternative deployments for a given SaaS. In the context of GreenIT Cloud Language Unity finally groups all the above challenges into the definition of a multi-view dynamic language, which is continuously synchronized with the SaaS, independently of its current state
