Bundles are collections of charms that link services together, so you can deploy whole chunks of infrastructure in one go.

Charms contain scripts that simplify the deployment and management of a service.

Model

With Juju, relationships between linked charms are formed automatically.

Easily configure charms via the inspector.

Deploy

Deploy and redeploy to all major public clouds or locally on your own hardware.

Monitor, maintain and scale on demand.

Why use Juju?

Whether it involves deep learning, container orchestration, real-time big data or stream processing, big software needs operations to be open source and automated.

Juju is the best way to encapsulate all the ops knowledge required to automate the behaviour of your application.

What people are saying about Juju

Spicule logo

Using the modelling ethos brought by Juju allows me to quickly run big data applications in a multitude of places.

Be it locally on my laptop, on bare metal or in the Cloud, Juju lets me reuse the same models and code without changing any aspects of my deployment.

Juju enables you to encapsulate each different part of your infrastructure and lets everything talk to each other.

So if you have a web server that’s managed by Chef and a database that’s deployed by a Docker container, you can have the web server talk to the database and the relations between these two very easily.

Juju acts as a thin layer on top of your infrastructure that allows all your operational code to talk to each other.

And because of this communication layer, a lot of the problems that conventional configuration management systems have just don’t exist anymore.
