Sveltos is a Kubernetes controller that automates the deployment of applications and configurations across large-scale fleets. By using declarative "ClusterProfiles," it identifies target clusters via labels and ensures they consistently run the required resources. It features an event-driven framework to detect and remediate configuration drift or health issues automatically. Ultimately, Sveltos simplifies multi-cluster management, making it an ideal "central brain" for edge and multi-cloud environments.
