## ✨ What is Constellation?
|
|
|
|
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.

## 🛠 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
