Constellation

Always Encrypted Kubernetes

Constellation License Govulncheck Go Report Discord Twitter

Constellation is a Kubernetes engine that aims to provide the best possible data security. It wraps your K8s cluster into a single confidential context that is shielded from the underlying cloud infrastructure. Everything inside is always encrypted, including at runtime in memory. For this, Constellation leverages confidential computing (see the whitepaper) and more specifically Confidential VMs.

Concept

Goals

From a security perspective, Constellation is designed to keep all data always encrypted and to prevent access from the infrastructure layer (i.e., remove the infrastructure from the TCB). This includes access from datacenter employees, privileged cloud admins, and attackers coming through the infrastructure (e.g., malicious co-tenants escalating their privileges).

From a DevOps perspective, Constellation is designed to work just like what you would expect from a modern K8s engine.

Use cases

Encrypting your K8s is good for:

  • Increasing the overall security of your clusters
  • Increasing the trustworthiness of your SaaS offerings
  • Moving sensitive workloads from on-prem to the cloud
  • Meeting regulatory requirements

Features

🔒 Everything always encrypted

  • Runtime encryption: All nodes run inside AMD SEV-based Confidential VMs (CVMs). Support for Intel TDX will be added in the future.
  • Transparent encryption of network and storage: All pod-to-pod traffic and all writes to persistent storage are automatically encrypted
  • Transparent key management: All cryptographic keys are managed within the confidential context

🔍 Everything verifiable

🚀 Performance and scale

  • High availability with multi-master architecture and stacked etcd topology
  • Dynamic cluster autoscaling with verification and secure bootstrapping of new nodes
  • Competitive performance (see K-Bench comparison with AKS and GKE)

🧩 Easy to use and integrate

Getting started

If you're already familiar with Kubernetes, it's easy to get started with Constellation:

  1. 📦 Install the CLI
  2. ⌨️ Create a Constellation cluster in the cloud or locally
  3. 🏎️ Run your app

Constellation Shell

Live demos

We're running public instances of popular software on Constellation:

These instances run on CVMs in Azure and Constellation keeps them end-to-end confidential.
