Learn About Confidential Clusters
Red Hat, Wednesday, September 3rd, 2025
The Confidential Clusters project integrates confidential computing technology into Kubernetes clusters. It's an end-to-end solution that provides data confidentiality on cloud platforms by isolating a cluster from its underlying infrastructure.
In a confidential cluster, all nodes run on top of confidential virtual machines (cVM). Before a node can join the cluster and access secrets, the platform and environment's authenticity are verified through remote attestation. This process involves communication with a trusted remote server.
