Welcome to Constellation!

Constellation is the first Confidential Kubernetes platform. It leverages confidential computing to isolate entire Kubernetes clusters and all workloads from the rest of the cloud infrastructure.

From the inside, it's a fully featured, [certified] Kubernetes engine. From the outside, it's an end to end isolated, always encrypted stronghold. A Confidential Cloud in the public cloud. Constellation is open source and enterprise-ready, tailored for unleashing the power of confidential computing for all your workloads at scale.

For a brief introduction to the Confidential Kubernetes concept, read the [introduction][confidential-kubernetes]. For more elaborate overviews of Constellation, see the [architecture] documentation. ## 🛠 Features ### Everything always encrypted - Memory runtime encryption of all Kubernetes nodes - [Transparent network encryption][network-encryption] for the entire cluster node to node traffic. Provided by [Cilium], application independent, no sidecar required - [Persistent volume](https://kubernetes.io/docs/concepts/storage/persistent-volumes/) encryption for block storage. [Encrypted in the confidential Kubernetes context][storage-encryption], keys and plaintext data never leave the cluster. No trust in the cloud storage backend required - [Key management][key-management] for transparent network and storage encryption ### Everything verifiable - [Verifiable][cluster-attestation] integrity and confidentiality of the entire Kubernetes cluster - Kubernetes node attestation based on confidential computing. Nodes are [verified][node-attestation] on their integrity and identity with a hardware-based remote attestation procedure before joining the cluster - [Supply chain protection][supply-chain] with [sigstore](https://www.sigstore.dev/) - [Confidential computing-optimized][images], fully measured, and integrity-protected node OS ### Performance and scale - High-available, enterprise-ready Kubernetes engine - Multi-master architecture - [Stacked etcd topology][etcd-stacked] - Dynamic cluster autoscaling ### 100% compatibility

- [Certified][certified] Kubernetes engine - Works with all your existing containers and tools - The only cloud-agnostic Confidential Kubernetes platform - Aligned to the [version support policy of Kubernetes][k8s-version-support] - [Cilium][Cilium] networking ## 🚀 Getting started ![Constellation Shell](docs/constellation-shell-windowframe.svg) Sounds great, how can I try this?
