The 4CaaSt project aims to create an advanced PaaS Cloud platform which supports the optimized and elastic hosting of Internet-scale multi-tier applications.

The goal of CloudScale is to aid service providers in analysing, predicting and resolving scalability issues, i.e., support scalable service engineering. The project extends existing and develops new solutions that support the handling of scalability problems of software-based services.
