jsondiff VS Juju

I currently work for a company that provides a security operations center to major corporations and governments. In my current role, the most important language is Python since any non-developer in our company still often knows Python due to the nature of their work, but I wrote a reasonably complicated Lambda in Go and have contributed to some Go open source projects we depend upon (Argo). There are a range of libraries I've used from github.com/nsf/jsondiff to AWS SDK stuff to Zap (a logging lib from Uber) to Hashicorp Vault stuff and testify for testing purposes. I've also had to use yaml, and I used the K8s library for that. I can't think of too much else I've used outside the standard library offhand.

Basically juju is used to deploy microservices, and other stuff too: https://juju.is/

Each app is packaged in a charm which seems to be a yaml declaring inputs, dependencies and other meta data and optional python code that can respond to certain lifecycle hooks

I am currently working myself through setting up our new Research GPU-Cluster where we have "sort of" managed to deploy MAAS to manage all the servers more efficiently, and on top of MAAS then use Juju to deploy the further components of the cluster. The components here are

Kubernetes Custom Resources were created to allow the Kubernetes API to be extended for domain-specific logic, by defining new resource types and controllers. OSS frameworks like operator-sdk, kubebuilder and juju were created to simplify the creation of custom resources and their controllers. Tools built with these frameworks came to be known as Operators.

Depending on what you're trying to accomplish, Juju and MAAS, if not just automate with preseed for custom desktops.

At Canonical I work on two open-source projects written in Go: Juju, a large cloud-based application deployment tool, and Pebble, a small Linux service manager. Both include CLI clients and API-based server daemons. Juju in particular is a large distributed system.

The new Portainer charm allows users of Canonical’s Charmed Kubernetes distribution to automatically install and integrate Portainer Business as part of the Kubernetes cluster deployment process, using Juju, the Charmed Operator framework.
