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] 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/static/img/constellation-shell-windowframe.svg) Sounds great, how can I try this?
