Deployment of Nuclia: in our cloud or in your infra.

For most organizations,
the elegant E2E solution

Once the data is fed, Nuclia will process it & store it on its own cloud located in the Europe region. Then, just setup the search, the answers, the training & the UI component.

For organizations who want data on sight, a hybrid solution with a twist

Same as the E2E solution but with a big plus, data will be processed in Nuclia’s cloud and stored in your own local instance of NucliaDB. Nothing gets stored in Nuclia’s cloud.
