Apache Jena Fuseki is one of the popular open-source RDF graph databases (triplestores). It is an essential component of a reliable, low-cost Knowledge Graph infrastructure.
Fuseki complies with the SPARQL 1.1 specification and supports SPARQL query and update as well as SPARQL Protocol and Graph Store Protocol.

Fuseki has a low footprint yet great scalability which makes it suitable as a backend for any kind of RDF datasets, from personal dataspaces to moderately-sized enterprise Knowledge Graphs.
We have packaged it as a Docker container-based product that can be installed into your AWS infrastructure with a few clicks of a button. The best part: it's free!
