Step | Description of action | Dependency on 3rd party services (EOSC-hub or other) |
|---|---|---|
UC1 | The DODAS admin requests the automated deployment of a DODAS cluster | TOSCA template to be submitted to the PaaS Orchestrator |
UC2 | The DODAS admin checks the status of the DODAS core services | Needs integration with some monitoring service. Is there anything already available in EOSC-hub? |
UC3 | DODAS Users access remote stored data from the DODAS cluster | Cluster configuration shall support OneData/XRootD integration. XRootD is maintained externally to EOSC-hub |
| UC4 | Jobs User jobs running on DODAS clusters store temporary data on local cluster | |
| UC5 | Jobs User jobs running on DODAS clusters access software from specific file system path | |
| UC6 | User jobs require to move input and output sandbox without the needs of moving data through storages (manually) | |
| UC7 | DODAS admin and users authenticate against a single AAI system | INDIGO-IAM |
| UC8 | Resource providers authenticate and authorize DODAS requests with INDIGO-IAM tokens | Integration through AAI EOSC-hub solutions |
| UC9 | Accounting data are gathered from the resource providers |
