Software

NGINX is an open-source HTTP and reverse proxy server. Domino uses NGINX to serve the Domino web application, and as a reverse proxy to route requests to internal services.

The Domino application exposes the Domino API and handles REST API requests from the web application and user clients.

The Domino dispatcher orchestrates workloads on compute nodes. The dispatcher launches new compute pods, connects results telemetry back to the Domino application, and monitors the health of running workloads.

Keycloak is an enterprise-grade, open-source authentication service. Domino uses Keycloak to store user identities and properties. It can also be used for identity brokering or identity federation to SSO systems and identity providers.

MongoDB is an open-source document database. Domino uses MongoDB to store Domino entities, like projects, users, and organizations. Domino stores the structure of these entities in MongoDB, but underlying data is stored separately in encrypted blob storage.

Git is a free and open-source distributed version control system. Domino uses Git internally to revision projects and files. Domino Executors also run Git clients, and they can interact with user-controlled external repositories to access code or data.

Elasticsearch is a distributed, RESTful search and analytics engine. Domino uses Elasticsearch to power user searches for Domino objects like projects, files, and models. Domino also uses Elasticsearch for logging.

The Docker registry stores and distributes Docker images. Domino uses its registry to store images for Domino environments and Model APIs. These images are built to user specifications by compute nodes.

Fluentd is an open-source application that unifies and processes logging and telemetry data. Domino uses Fluentd to aggregate logs and forward data to durable storage.

Redis is an open-source data structure cache. Domino uses Redis to cache logs in-memory to stream back to users through the web application.

RabbitMQ is an open-source message broker. Domino uses RabbitMQ as an event bus to asynchronously distribute event messages between Domino services.

Postgres is an open-source relational database system. Domino uses Postgres as a storage system for Keycloak data on user identities and attributes.
