After the large penetration of Cloud Computing, more and more developers are taking into account migrating their applications to the Cloud, in order to take advantage of the characteristics of this new environment. In close relation with application migration, an increasing number of development and execution platforms, delivered as PaaS solutions (such as mOSAIC, 4CaaSt, Cloud Foundry, Open Shift, Stackato, and others) are offering their services for development, deployment, and execution of applications that are using in an optimum manner the five characteristics of the Cloud. Following this massive migration of applications, especially from SOA, to Cloud environments, new requirements for application development could be identified in order to enable the construction of complex solutions, and to exploit a business level on the top of various *-as-a-Service layers. The introduction of a centralized component, the Cloud Governance, is necessary in order to enable the development of complex cloud ecosystems. This centralized component is extending, complementing, completing and integrating core features from the PaaS layer, like monitoring, provisioning, negotiation, and others, and integrate features of various Cloud management solutions.
