Spinnaker is an open-source, multi-cloud continuous delivery platform that helps you release software changes with high velocity and confidence.
You use Spinnaker’s application management features to view and manage your cloud resources.
Modern tech organizations operate collections of services—sometimes referred to as “applications” or “microservices.” A Spinnaker application models this concept.
Applications , clusters , and server groups are the key concepts Spinnaker uses to describe your services. Load balancers and firewalls describe how your services are exposed to users.
An application in Spinnaker is a collection of clusters, which in turn are collections of server groups. The application also includes firewalls and load balancers.
An application represents the service which you are going to deploy using Spinnaker, all configuration for that service, and all the infrastructure on which it will run.
You will typically create a different application for each service, though Spinnaker does not enforce that.
You can define Clusters, which are logical groupings of Server Groups in Spinnaker.
