## What it is
Juju is Canonical's open-source orchestration engine for deploying, integrating, and managing the lifecycle of applications at any scale using reusable operators called 'charms'. It works uniformly across Kubernetes, public clouds, VMs, and bare metal, with a CLI client and controller architecture.

## Use cases
- deploy postgresql on kubernetes with one command
- manage application lifecycle across multiple clouds
- integrate observability stack components automatically
- orchestrate charmed applications on bare metal
- scale and upgrade deployed software operators
- model multi-application systems with relations between services

## When to choose
- you want declarative, operator-based deployment across Kubernetes and VMs with the same tooling
- you rely on the Charmhub ecosystem of pre-built operators for databases, observability, and infrastructure
- you need lifecycle management (deploy, integrate, scale, upgrade) as first-class operations

## When to avoid
- you only need plain Kubernetes manifests or Helm charts without an operator abstraction layer
- you want a lightweight single-binary deployer with no controller/agent architecture
- your team is unwilling to learn the charm model or maintain custom charms
