Paul Chiusano announces that Unison Cloud, which turns a pool of nodes into a distributed computer programmable in Unison, is now MIT licensed, newly open-sourcing the Nimbus worker node, the Haskell Cloud API server and the Unison Cloud UI alongside the existing client.

Unison Cloud is now open source

Unison Cloud is now open source, MIT licensed. There are four projects:

What is Unison Cloud?

Unison Cloud turns any pool of nodes into a distributed computer, programmable with the Unison language. See a series of demos. Some features:

Service deploys in seconds. Services are lightweight, < 200kb. No more building and shipping around multi-GB containers.
Fast, typed, inter-service communication using adaptive service graph compression .
Distributed batch jobs, using a high-level fork/join style distributed computing model.
Transactional storage (backed by DynamoDB) and object storage (backed by S3).
Secrets management, long-running background jobs, and more.
The Unison Cloud client defines the programming model for a Unison Cloud cluster. It includes both a local interpreter (for testing and local development) and the real interpeter that talks to a distributed Unison cluster. This has been open source for a long time.
Nimbus is the worker node for a Unison Cloud cluster. It is written in Unison. The system supports any number of workers, and can be scaled dynamically up or down. This is newly open sourced.
The Unison Cloud API Server is a Haskell service that the Unison Cloud client talks to when interacting with a remote Unison Cloud cluster. It also acts as a control plane for tracking cluster membership, handling authentication, and so on. This is newly open sourced.
The Unison Cloud UI is the code behindapp.unison.cloud (for viewing deployed services, logs, and so on). This is newly open sourced.
