Spinnaker

Spinnaker. Is an open source multi-cloud continuous delivery platform.

Summary

Strengths: mature deployment strategies (red/black, canary); broad provider support; strong fit when teams already invested in Spinnaker ops.

Weaknesses: heavy operational footprint (multiple microservices); steep learning curve; many orgs now prefer Git-declared desired state plus ArgoCD or managed CD.

When to use: existing Spinnaker estate; complex multi-account AWS/GCP promotion with battle-tested runbooks.

When to skip: new platforms; small teams; Kubernetes-only shops that can standardize on Argo CD or GitHub Actions deploy workflows.
