Conclusion & Perspectives
soCloud is a distributed PaaS, that provides a model for building any multi-cloud SaaS applications
We describe the approach used by the soCloud to achieve portability, provisioning, elasticity and high availability
We explained how the components in a SaaS application descriptor can be annotated with elasticity rules, placement constraints, computation constraints.
In comparison of soCloud availability with public cloud availability, we demonstrate that soCloud ensures high availability in minutes
We have analysed the flash crowd phenomenon on a use case, and demonstrated how the soCloud platform increases the elasticity of the application

We will investigate in how to overcome the constraint which consists to build the SaaS application with SCA model
