Given the above, the following design-goals follow:
- Support multiple cloud vendors across multiple NRENs
- Easy migration from existing visualization platforms
- Allow for university datacenter networks to be extended to cloud providers
- Low/zero maintenance and end-user tools for provisioning

- All cloud service providers are connected to the NRENs (eg SUNET) over a transparent MPLS service provided by NORDUNet.
- Private cloud services shared between universities are connected using a similar MPLS service
Service design
The service presented to the end-user should be as simple as possible. There are two basic tools/services
- A tool for network provisioning, i.e setting up a connection between a vlan on the hosting provider to a vlan in the university datacenter
- A tool for host provisioning, i.e setting up resources in the hosting providers clusters
Both tools need to be enabled for federated AAI and integrated into Kalmar2. Procurement of hosting providers must include requirements for AAI integration. Part of the work on the greeqloud PoC involves developing AAI support for OpenStack which is used by greeqloud. In the process we will gather requirements for future RFPs in this field.
