Setting Up a Datacenter with EBS Encryption
Datacenters running on Amazon’s EBS infrastructure can be encrypted with an AWS KMS key. This will encrypt both your EBS volumes and S3 backups. This involves a few steps to set up:
In your AWS account:
- Go to key management service
- Create/view an AWS Encryption Key in the datacenter’s intended region.
- Go to Account → Encryption Keys to add encryption keys.
- You’ll need the AWS key’s ARN, found in the key’s details after key creation.
- The alias will identify this key in other parts of the Instaclustr console.
- When you Create a cluster or Add a datacenter:
- Select an EBS-based Node Size
- Under EBS Encryption, select Encrypt data at rest and select a key from the dropdown. The keys listed will be those that have been previously added and are in the same region as the datacenter being requested.
- Finish the create a cluster or add a datacenter process to provision the encrypted datacenter.That’s it! Encryption and decryption will be handled transparently by AWS’ Key Management Service, so use the datacenter as you would with a datacenter of no encryption.
In your Instaclustr account:

Enabling this feature on existing cluster
Most clusters will require a DC migration to move to encrypted EBS.
Set up your AWS Encryption keys as per the process above, and email firstname.lastname@example.org to request adding this on your existing cluster.
