Cloud instances
Characteristics
In addition to the characteristics available for a server, you can use the following:
| Name | Unit | Default value | Description | Example | 
|---|---|---|---|---|
| usage | None | See cloud usage | .. | 
Cloud usage
In addition to the characteristics available for server usage, you can use the following:
| Name | Unit | Default value | Description | Example | 
|---|---|---|---|---|
| instance_per_server | None | None | See usage | 10 | 
| hours_life_time | hours | 35040 | Lifespan of the cloud element | 2 | 
| use_time_ratio | /1 | 1 | Proportion of time the device is used during the given duration. | 0.5 |

Method
Embedded impacts of cloud instances correspond to the impact of the physical server hosting the instance divided by the number of instances hosted on the server.
\[
\text{cloud_instance}_\text{embedded}^\text{criteria} = \frac{\text{server}_
\text{embedded}^\text{criteria}}{\text{instances_per_server}}
\]
Components configuration are never sent by the user but pre-recorded as an archetype.
Usage impacts
Usage impact of cloud instance are measured only from its consumption profile.
As for embedded, usage impacts for a physical server are divided into the number of instances hosted by the server.
Consumption profile
We use the same process as described for the servers .
