Fly.io (que certains présentent comme la principale alternative à Heroku) est, comme beaucoup de plateformes d’infrastructure, un système complexe construit sur un certain nombre de projets open source avec notamment Nomad, Consul et Vault de Hashicorp.

Au cœur de l’exécution des applications se trouve une variante de Firecracker d’Amazon. Et une surveillance avec des tableaux de bord utilisant Prometheus et Grafana.

[Fly and Open Source](https://fly.io/docs/about/open-source/)

Fly.io utilise des microVMs Firecracker. Il s’agit de machines virtuelles légères et sécurisées basées sur une virtualisation matérielle forte.

Les machines Fly sont des VM Firecracker dotées d’une API REST rapide qui peuvent démarrer des instances en 300 ms environ, dans toutes les régions prises en charge par Fly.io.

[Run User Code on Fly Machines](https://fly.io/docs/machines/guides-examples/functions-with-machines/)

Une des utilisations des machines est d’exécuter du code utilisateur pour étendre votre service, ou comme un service en soi. On appelle parfois cela “Functions-as-a-Service” (FaaS). L’idée générale est la suivante :

> emballer le code des utilisateurs

> définir un environnement d’exécution

> lancer le code dans une VM

> puis éteindre la VM lorsqu’elle est inactive afin d’économiser sur les factures de calcul.

> Le tout en facturant les utilisateurs à la demande ! …

Je vais m’interesser ici au projet JupyterLite. JupyterLite est en effet une distribution JupyterLab qui s’exécute entièrement dans le navigateur, construite de A à Z à partir de composants et d’extensions JupyterLab.

[JupyterLite - JupyterLite 0.1.0-beta.18 documentation](https://jupyterlite.readthedocs.io/en/latest/)

Bien que JupyterLite soit actuellement développé par les développeurs principaux de Jupyter, le projet est encore non officiel.

Et génération du contenu statique dans un répertoire contenant JupyterLite et ses extensions via cette commande :

> Maintenant que les actifs statiques ont été construits, vous pouvez utiliser un serveur HTTP simple pour les servir et accéder à JupyterLite depuis un navigateur web.

La commande **_jupyter lite serve_** offre soit un serveur web propulsé par le module **_http.server_** intégré de Python, soit **_Tornado_** , qui sera probablement disponible si d’autres outils Jupyter sont installés :

```bash

(base) ubuntu@julia50b1000001:~$ jupyter lite serve

            /home/ubuntu/dist/_output

Il ne me reste plus qu’à l’empaqueter pour le déployer dans la plateforme fly.io. Pour cela je m’inspire de la fiche documentaire consacrée au déploiement de contenus statiques :

This is flyctl, the Fly.io command line interface.

It doesn't look like you're logged in. Try "flyctl auth signup" to create an account,
or "flyctl auth login" to log in to an existing account.

flyctl does a lot of stuff! Don't panic, it's easy to get started:

  * fly launch: launch a new application ("fly help launch" for more)

  * fly apps: create and manage apps ("fly help apps")

  * fly machines: create and manage individual Fly.io machines ("fly help machines")

  * fly postgres: create and manage Postgres databases ("fly help postgres")

  * fly redis: create and manage Redis databases ("fly help redis")

  * fly help: for more help, and a complete list of commands.
