The usage of the infrastructure services of multiple Clouds, either to easily migrate an application from one Cloud to another, or to benefit from the special facilities of particular Clouds, requires to reach a certain level of application portability and technology independence which are currently hardly reachable in the absence of well established standards. One possible approach is to design a set of open APIs which can offer a level of abstraction that ensure the vendor agnosticity. Moreover, such a set of API should be integrated in an open-source alternative to the existing platforms allowing the usage of services from multiple providers of infrastructure services, and releasing the application developer from the burden of remote infrastructure settings. A recent open-source API and platform-as-a-service for multiple Clouds, namely mOSAIC, shortly presented in this paper, proves the viability of such an approach through its recent software releases and initial test results. While the proposed solution was presented earlier, in this paper we discuss how we can ensure a certain level of dependability for Cloud computing using mOSAIC.
