Companies and developers stick in a dilemma. On the one hand, cloud computing should provide easy access to IT resources. But on the other hand, an enormous knowledge about distributed programming is assumed, to create solutions that are both scalable and highly available simultaneously. In particular, the issue of the responsibility for scalability and high availability for the virtual infrastructure respectively of the web application is largely suppressed by the cloud providers. This leads to a higher complexity of knowledge on the way into the cloud and to a lack of the seemingly simple use of cloud services. Furthermore, the cloud is currently lacking of complete services that represent individual modules for a specific business scenario and can be adapted easily and independently from each other.
