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:

  1. Go to key management service
  2. Create/view an AWS Encryption Key in the datacenter’s intended region.
  3. Add the AWS account ID (e.g. Your Provider account)  that this key would grant access to. In the example above it gives access to Instaclustr’s account (624537489435) as an External Account

    In your Instaclustr account:

  4. Go to Account → Encryption Keys to add encryption keys.
  5. You’ll need the AWS key’s ARN, found in the key’s details after key creation.
  6. The alias will identify this key in other parts of the Instaclustr console.
  7. When you Create a cluster or Add a datacenter:
  8. Select an EBS-based Node Size
  9. 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.
  10. 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.

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 to request adding this on your existing cluster.
