Experts are predicting the cloud software market to grow at a high rate in the coming years. Merrill Lynch and Gartner predict the cloud computing market to be worth between $160 and $150 billion in 2013. Many computing services have now migrated to the cloud and many applications are becoming cloud-based and function as standalone or in orchestration with other cloud-based services. With the advent of the cloud and the reliance on Big Data, cloud-based systems are driving our digital economy and increasingly becoming pervasive in many daily applications. Cloud has become the backbone for many e-businesses; engineering, scientific and experimental processes; real-time control and monitoring data intensive systems such as disaster management, weather and  climate predictions, which heavily depends on the Big Data thing. The dependability of these systems and their continuous evolution are essential pre-requisite for the success and prosperous growth of our digital economy. The “cloud wave” has urged the need for advancing the fundamentals of cloud software engineering, supporting the emergence and the advancement of this emergent digital economy
