The user must understand the relationship between DIET Deltacloud and the Cloud system it is using. A Cloud system is seen as a provider of on-demand resources and as such, the DIET Deltacloud SeD is the front-end to the Cloud system from the DIET user's point of view.
The DIET platform remains completely outside of the Cloud system and virtual resources are instantiated based on how they are needed. These virtual resources contain the task that solves the service required by the DIET client. It is the responsibility of the DIET service creator to provide Virtual Machine images that contain the service implementation.
The DIET Cloud system is part of the DIET Batch system and it is recommended that the user reads the corresponding chapter before the current.
