Nua is an open source cloud platform project launched by Abilian in 2021. It offers a PaaS (platform as a service) that can be easily installed on bare metal or virtualised servers, and which allows containerised web applications to be run, managing their lifecycle, the providers they need (storage, databases, etc.), user access rights, backups, monitoring, logs, etc.

Nua enables the management of applications from an application portfolio (“marketplace”), i.e. packaged and optimised by the platform’s developers (or third parties). Nua also allows the deployment of applications under development (demo / qualif / prod), including several instances of the same application, and including automatic deployment (example use case: create demo instances on request from prospects, optimising provider consumption).

Nua is based on the main standards of the open source and cloud world: database (Postgres, MySQL, MongoDB, Redis), storage (S3), OCI, dockerfiles and buildpacks, LDAP and SSO, etc. Nua currently relies on Docker, but will eventually allow applications to be deployed in other execution environments (other containers, classic or lightweight VMs, SlapOS…).

Presentation outline

  • Vision and main features of the project

    • Simplification of packaging and multi-instance deployment,
    • Self-hosting, digital sovereignty
    • General architecture
  • Why python?

    • A python runtime in the container
    • An orchestrator driving the containers
    • Reuse of components between packaging, script execution and orchestration
  • Examples and demo

    • Configuration file (packager view)
    • Deploying configurations (user CLI view)
  • Roadmap and how to contribute


  • For developers / devops: how Nua can help to quickly deploy dev versions in the dev / preprod / prod phase, and to manage production constraints (backup, upgrades)?
  • For IT managers: how can Nua help to easily deploy and manage a portfolio of open source Web applications (intranet / extranet / Web)?
  • For third-party application developers: how to port their applications to Nua?
  • For open source contributors: what is Nua’s roadmap and how to contribute to it?
