Cloud-Aware Middleware

The exponential growth of cloud computing popularity in the last years brings up new possibilities to reduce costs and places new challenges for application and middleware developers. As usually adopted, applications are developed atop middleware systems whose role is to hide the complexity of underlying cloud technologies and distribution mechanisms. However, traditional distribution transparencies and services provided by off-cloud middleware need to be redesigned in order to leverage cloud computing facilities and capabilities such as elasticity, infinite resource illusion, virtualization, and so on. In this context, this paper proposes a middleware, namely CaMid, which takes advantages of the inherent cloud characteristics and made available them to applications in a transparent way, i.e., applications developers are kept away from IaaS and distribution mechanism complexity. In order to evaluate the CaMid, we carry out an experimental assessment to measure its impact on the performance of distributed applications.
