S4 provides a fully-managed RDF graph database-as-a-service (DBaaS) based on the Onotext GraphDB database.
Access to the database is via a simple RESTful API (OpenRDF API) and provisioning, operations, maintenance and upgrades are managed by the S4 platform on behalf of developers
The DBaaS version of GraphDB in the Cloud intends to be used for scenarios with small or medium database size and query load, where investing in software licenses and provisioning and maintaining an on-premise 24/7 server is not cost optimal.
