Hybrid cloud architectures for the online commerce

Cloud Computing is a relatively new computing approach which promises enhanced scalability, flexibility and cost-efficiency. In practice, however, there are many uncertainties about the usage of this way of provisioning IT resources. Concerns about evolving dependencies and security issues have arisen. As online commerce is dependent on a reliable, secure online stores, it is vital to take those concerns into account. The hybrid architecture combines traditional IT service provisioning with the usage of internet-based services. This approach would help to harness the strengths of Cloud Computing, while minimizing the impacts of its potential risks. This article discusses hybrid cloud architectures with the focus on realizing shop functionalities. Advantages and drawbacks of integration for each service type in the Cloud Computing stack are given, from which possible problems of hybrid clouds are derived. The conclusions in this article provide a conceptual basis for further research and evaluation of the use of net-based services in the field of online commerce.
