The following preliminary service scenarios are envisioned:
- Hosted Service Scenarios
- A) One cloud broker instance is hosted at a central location (e.g., TERENA offices), metadata is stored at the same place (i.e. inside the broker), storage data is stored in the public cloud contracted by TERENA - This is the scenario of the current pilot installation!
- B) One cloud broker instance is hosted at a central location (e.g., TERENA offices), metadata is stored at the same place (i.e. inside the broker), storage data is either stored in the public cloud or in the data storage facilities provided by NRENs participating in the pilot coordinated by TERENA.
- Brokered Service Scenarios
- A) Several cloud broker instances are hosted by NRENs or end-sites, metadata is stored locally (i.e. inside the distributed brokers), storage data is stored in the public cloud that is brokered to NRENs by TERENA.
- B) Several cloud broker instances are hosted by NRENs or end-sites, metadata is stored locally (i.e. inside the distributed brokers), storage data is stored in the mix of public cloud and data storage facility of NRENs brokered and coordinated by TERENA.
Other potential scenarions may come up...
