This document is a presentation about Juju and DevOps given by Sidnei da Silva. It discusses how Juju allows developers to easily deploy applications across multiple servers, reproduce deployments for testing, rapidly deploy dependencies, explicitly connect components, monitor deployments in real time, and collaborate between developers and operations teams. Juju uses charms to define how to install and configure applications, makes it simple to scale applications by adding more units, and handles provisioning, installation, configuration, and relations between services.
