Do you mean AGPL? GPL backend/database code can be modified (i.e. to integrate with Amazon internal systems) and run as a service without releasing modifications, so long as none of the covered code (only its outputs) are "distributed" to end users. AGPL is specifically designed to work around that, but most folks don't release as AGPL (likely because it's that much easier to spread FUD about it); https://neo4j.com/ https://neo4j.com/ is one exception. https://www.gnu.org/licenses/agpl-3.0.en.html https://www.gnu.org/licenses/agpl-3.0.en.html
