This includes the [Helmholtz Cloud](https://helmholtz.cloud), where members of the Helmholtz Association of German Research Centres provide selected IT-Services for joint use.
## Purpose
This is to document the calculcation of the **Helmholtz Cloud Service Operation KPI** (WP 1.4) for Helmholtz Cloud Services by the HIFIS Cloud Cluster Management of HIFIS. For further information, see <https://hifis.net> and [Original platform proposal for HIFIS](https://www.helmholtz.de/fileadmin/user_upload/01_forschung/Helmholtz_Inkubator_HIFIS.pdf), Page 56 about WP 1.4.

## Regular Measurement Series and Calculation
Each [Helmholtz Cloud Services](https://helmholtz.cloud/services) determine **regular measurement series**that reflect the current usage. The measured raw values show as best as possible how much the service is used. Accordingly, the character of the measurement series depends on the character of the service and varies from service to service.

The measured raw values indicate how much the individual service is used. Accordingly, the character of the measurement series depends on the character of the service and varies from service to service.
All steps of the calculation are publicly available, i.e. scripts, intermediate results, final result.
The numeric information are collected in a common public repository at
- All steps of the calculation are publicly available in a [**public repository**](https://gitlab.hzdr.de/hifis/overall/kpi/kpi-plots-ci), i.e. scripts, weighting, intermediate results, final result. The full history is accessible.

## Interpretation of the KPI
Generally, the KPI represent both individual users (50%) and resource usage (50%) of Helmholtz Cloud services.
Positive KPI can be interpreted as increased usage in relation to when the serivce was added to the Helmholtz Cloud; negative values would indicate decreased usage.
Addition of more services (# services) and/or increased number of users per service and/or increased usage of services lead to an increasing KPI.
Therefore, one can interpret the KPI as follows:
- Overall KPI (third column below) indicate the **quantitative** development of the Helmholtz Cloud services over time.
- Overall KPI divided by numbers of services (fourth and fifth column below) indicate the **qualitative** development of the Helmholtz Cloud Services, i.e., the average user acceptance per service over time.
