Most terms for cloud environments e.g.: open clouds, public clouds are described from the application or customer view. From our perspective, we require a technological and operational view. We apply the following terms in our documents:
- IT-element: We use this term for all kinds of components of an IT infrastructure, for instance, LAN switches, SAN storage devices, servers.
- On-premise solution: These IT infrastructure models employ on-premise software products which lead to a close interconnection between the software and the hardware. The on-premise model is slowly being replaced by the cloud model, but still has a wide customer system distribution.
- Enterprise cloud solution: With these IT infrastructures, the applications are embedded in a dynamic IT framework. These applications, e.g., standard databases, are not designed with an open cloud software standard. The dynamics and resilience of the application is mainly is mainly hardware driven.
- Open cloud solutions: Core element in this particular cloud platform is, contrary to the enterprise cloud solution, driven by the application, e.g., web Services.
