1. Department of Computer Science and Engineering, and KINDI Laboratory for Computing Research Joint Seminar Cloud computing is a paradigm shift to a new enterprise distributed computing which takes place outside of the cloud consumer’s enterprise environments. In cloud computing, everything is considered a service such as software services, application development platform, and infrastructure supports. These characteristics of cloud computing require enterprise architecture to be redefined in terms of changing roles of key architectural components. In this presentation we show how the characteristics of cloud computing affect the enterprise architecture in four domains: business, data, application and technology. The ownership and control of architectural components are shifted from organisational perimeters to cloud providers. We demonstrate with a running example that although cloud computing promises numerous benefits to enterprises, the shifting control from clients to cloud providers introduces several architectural challenges. The diminishing control of an enterprise on the architecture ultimately causes service inflexibility and data confidentiality problems. The organisational control on the enterprise data and business processes, and the cloud providers control on technology and services are the two critical issues that need to be addressed in the changing architectural framework. This presentation identifies the architectural components along with the issues and research challenges emerging from cloud-based enterprise architecture.
