GÉANT Federation as a Service - FaaS is an easy entry point for NRENs who are developing or are in early stage of operating an WebSSO Identity federation. FaaS service is offered to organisations which operate an Identity federation - Federation Operators to facilitate efforts needed for uptake and day-to-day operations. FaaS offer enables Federation Operator (typically an NREN) to roll out Identity federation services to their constituents in a way which accommodates best current practices for operating Identity federation and connecting to eduGAIN.
FaaS target users are Federations that are developing or in early stage of production. FaaS is offered at no additional costs to GÉANT partners. Current FaaS users are:
All level of support are provided by FaaS operations team.

Service is operated by GEANT project and offered to the Identity Federation operators in a form of SaaS offering. The request for the service is sent to the FaaS contact following procedure explained at https://wiki.edugain.org/Become_FaaS_user. Upon from receiving the request and all technical parameters, FaaS operations team deploys a single-tenant service instance for the Identity Federation operator. The FaaS instance is hosted on the domain chosen and provided by the Federation operator, and it is localized so that it looks like its in constituency of the Federation operator (localized language, logo etc.). FaaS offering is delivered in a way that is transparent to the Federation members.
FaaS operations team is responsible for maintaining and administering all deployed FaaS instances. Federation Operator personnel is responsible for using its FaaS registry to manage SAML metadata and to promote usage of the registry in line with local policies and practicies, to their members. Depending on that, administrators of IdPs and SPs, could also use their federation FaaS registry to registerer SAML entities.
FaaS toolbox is built by using open source tools sourced from the academic community:
Metadata aggregator used in FaaS is configured to consume eduGAIN metadata and registered local federation entities metadata and to produce two metadata streams:
Metadata aggregator is run:
Each federation using FaaS is provided with its own, single-tenant, FaaS instance. FaaS operations team is maintaining a FaaS instance for each user and also QA instances. All FaaS instances are described in FaaS instances configuration parameters. VM infrastructure is provided by PSNC.
Metadata aggregator signs the metadata using HSM - Hardware Security Module provided by NORDUnet. HSM is state of the art technology used for secure signing where signing key is stored in hardware.
There are two HSM partitions for all FaaS instances. Each partition is hosted on a different HSM appliance, located at different locations in Stockholm, Sweden. On each FaaS instance HA (High availability) group is defined and metadata aggregator is set to address its requests to the HA group instead of addressing its requests to any partitions directly. This approach provides:
