Definition
Spinnaker is an open-source, multi-cloud continuous delivery platform originally created by Netflix for releasing software changes with high velocity and confidence.
Overview
Spinnaker was built by Netflix and later developed jointly with Google to manage complex, large-scale deployment pipelines across multiple cloud providers and account boundaries. It models releases as pipelines composed of stages — such as running tests, baking a machine image, deploying to a canary environment, running automated analysis, and then rolling out to production — giving teams a structured, auditable process for shipping changes. A defining feature is Spinnaker's built-in support for advanced deployment strategies, including blue-green (red/black) deployments and canary releases, along with automated canary analysis that compares metrics between a new version and the baseline to decide whether a rollout should proceed or be rolled back automatically. It integrates with major cloud providers (AWS, Google Cloud, Azure), Kubernetes, and image bakeries, making it capable of deploying the same pipeline concept across heterogeneous infrastructure. Spinnaker is generally aimed at organizations operating at significant scale with sophisticated deployment requirements; smaller teams often find lighter-weight CI/CD tools, or Kubernetes-native GitOps tools like Argo CD, sufficient without Spinnaker's additional operational overhead.
