In their own words
Argo Workflows
Argo Workflows is a free, open-source engine for orchestrating container-based jobs on Kubernetes. Workflows can be arranged as sequential steps or as tasks linked in a directed acyclic graph, with each step running in a container. The project lists machine learning pipelines, data and batch processing, infrastructure automation, and CI/CD as use cases. Controls include loops, conditionals, retries, timeouts, suspension and resumption, cancellation, and limits on parallel work. Cron scheduling, workflow archiving, a UI for viewing and managing runs, and Prometheus metrics are included. Artifact support covers S3, Artifactory, Alibaba Cloud OSS, Azure Blob Storage, HTTP, Git, GCS, raw artifacts, and plugins. The server provides REST API support over HTTP and gRPC, with client libraries for Java, Go, Python, and TypeScript. Argo Workflows is self-hosted and can run on any Kubernetes cluster. Its listed plan costs nothing, and the official pages list no paid plans or usage limits. Administrators should configure transport security, authentication, roles, and permissions; workflow pods run as root by default unless their security context is set.
Juju
Juju is Canonical’s open source orchestration engine for deploying, connecting and managing application lifecycles with charms. A charm packages reusable business logic to automate parts of an application’s life. Juju treats application integrations as part of lifecycle management and can manage software across public clouds, Kubernetes, virtual machines and bare metal. It can apply networking and configuration changes between applications even when they run on different clouds. Charmhub is a curated marketplace with charms for tools such as PostgreSQL, MySQL, MongoDB, Kafka, Kubeflow, Apache Spark, Prometheus, Grafana, Loki, Vault, Traefik and Landscape. For enterprise use, JAAS provides a central control plane that can manage hundreds of Juju controllers. It adds fine-grained access controls, auditing and support for external identity providers through OIDC and single sign-on in the CLI and web dashboard. JAAS also has a graphical administration and monitoring dashboard. Juju is free and open source; listed platforms include Linux, macOS, Windows, API and self-hosted environments.
