Ubiquity and QoS for Cloud Security

Cloud computing brings many advantages in terms of externalization, service delivery, elasticity, dependability and scalability. Nevertheless, it can be exposed to several vulnerabilities and security attacks. Therefore, we propose, in our UBIS (Ubiquity and Integration of Services) project, an architectural model that aims to satisfy cloud user requirements and cloud security challenges. For this purpose, our solution is based on two key elements. The former deals with ubiquitous services in Service Oriented Architecture. The latter considers QoS management that includes security aspects based on Event Driven Architecture.
