Hi, We have released Fuseki (I believe 3.16.0) as a free container-based product on the AWS Marketplace: https://aws.amazon.com/marketplace/pp/prodview-vlw4v7stfhqsu
Some other triplestores are available there, and some have free trials, but the annual licenses go up into tens of thousands of dollars. We wanted to provide an alternative to that. The product comes with a CloudFormation template which makes the installation really easy, literally 5 button clicks. The features are really basic (no HTTPS, no authentication, no custom domains). An extended version is on the roadmap. Please give it a try, we welcome the feedback (and reviews). Martynas atomgraph.com
