# Product features
|
||
|
|
|
||
|
|
Constellation is a Kubernetes engine that aims to provide the best possible data security in combination with enterprise-grade scalability and reliability features---and a smooth user experience.
|
||
|
|
|
||
|
|
From a security perspective, Constellation implements the [Confidential Kubernetes](confidential-kubernetes.md) concept and corresponding security features, which shield your entire cluster from the underlying infrastructure.
|
||
|
|
|
||
|
|
From an operational perspective, Constellation provides the following key features:
|
||
|
|
|
||
|
|
* **Native support for different clouds**: Constellation works on Microsoft Azure, Google Cloud Platform (GCP), and Amazon Web Services (AWS). Support for OpenStack-based environments is coming with a future release. Constellation securely interfaces with the cloud infrastructure to provide [cluster autoscaling](https://github.com/kubernetes/autoscaler/tree/master/cluster-autoscaler), [dynamic persistent volumes](https://kubernetes.io/docs/concepts/storage/dynamic-provisioning/), and [service load balancing](https://kubernetes.io/docs/concepts/services-networking/service/#loadbalancer).
|
||
|
|
* **High availability**: Constellation uses a [multi-master architecture](https://kubernetes.io/docs/setup/production-environment/tools/kubeadm/high-availability/) with a [stacked etcd topology](https://kubernetes.io/docs/setup/production-environment/tools/kubeadm/ha-topology/#stacked-etcd-topology) to ensure high availability.
|
||
|
|
* **Integrated Day-2 operations**: Constellation lets you securely [upgrade](../workflows/upgrade.md) your cluster to a new release. It also lets you securely [recover](../workflows/recovery.md) a failed cluster. Both with a single command.
