Clouddriver

Clouddriver is the cloud-provider integration layer of Spinnaker, exposing a uniform API and cache for infrastructure resources across multiple clouds. It discovers and tracks entities such as server groups, load balancers, security groups, images, and instances, normalizing them so higher-level services can reason consistently. The service also brokers mutating operations—like creating server groups or resizing clusters—by translating Spinnaker requests into provider-specific calls. A scalable caching subsystem maintains near-real-time views of accounts and regions to keep UI and pipelines responsive. Credentials, permissions, and account configuration are managed centrally, enabling multi-account, multi-region deployments at scale. In practice, Clouddriver is the backbone that lets Spinnaker orchestrate hybrid and multi-cloud delivery with a single pane of glass.
