Third Party Services

The PHT relies heavily on other great open-source projects. Not only as libraries but also as standalone components of our architecture.

Central

Harbor

The container registry provided by the Harbor project is the central data/algorithm exchange platform of the PHT. Trains are defined as images which are distributed between the participants private harbor projects.

Vault

For securely storing sensitive user or train data as key-value pairs we utilize Vault by Hashicorp as secret storage for our central services.

Local

Apache Airflow

Apache Airflow is open source, community developed platform to programmatically author, schedule and monitor workflows and the primary component of the PHT Station.

FHIR

To overcome local setup differences between stations, the PHT provides controlled and reliable access to different FHIR Servers. We support the IBM FHIR Server, Blaze and HAPI server. University hospital Tübingen is using the IBM FHIR server.

Keycloak

A user within the central user interface has always to be associated to a station. Each station can independently use different IAMs. We in Tübingen use Keycloak for our user management.
