Control Plane vs Karmada

Control Plane virtualizes cloud infrastructure into an AI-native cloud for deploying workloads across infrastructure selected by the customer. It combines bare metal, Kubernetes, and regions from AWS, GCP, Azure, and OCI. Supported workloads include containers, virtual machines, and ephemeral isolated sandboxes. Universal Cloud Identity provides credential-free service access across clouds without embedding credentials in workloads. Networking includes a service mesh, per-workload firewalls, and outbound-only Cloud Wormhole tunnels to private networks. The platform lists infrastructure provisioning, governance policies, infrastructure as code, role-based access control, audit logs, and Kubernetes management. Integrations include Terraform, Pulumi, Datadog, Logz.io, and Coralogix. Capacity AI is described as right-sizing resources; the company says most customers cut cloud bills by 30–50%. Usage pricing is billed monthly without contracts, minimums, or lock-ins. CPU is $0.06205654 per millicore-month, memory $0.00706330 per megabyte-month, and SSD $0.21224989 per GB-month.

Karmada manages cloud-native applications across multiple Kubernetes clusters and clouds without requiring changes to the applications. It supports public and private cloud, on-premises, edge, and self-built environments that meet Kubernetes specifications. Cluster connections can use Push mode through a Kubernetes API server or Pull mode through an in-cluster agent. Scheduling policies cover cluster affinity, taints and tolerations, topology spread, and replicated or divided placement. OverridePolicy allows per-cluster changes to images, arguments, commands, and plain-text configuration. Karmada can move replicas after a cluster failure, including migration that avoids service replicas dropping to zero. Through karmada-apiserver, teams can create, update, delete, and query resources across member clusters. Its components export Prometheus metrics; integrations described include Submariner networking and ErieCanal service governance. Installation options include CLI tools, Helm, an operator, binaries, or source. The CLI initialization requires escalated privileges to store shared configuration under /etc/karmada by default. Karmada is open source and free, with customer-managed control plane; it manages clusters but does not provision them.
