Setting Up a Datacenter with EBS Encryption | Cassandra Documentation

Menu

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.

  1. Add Instaclustr’s account (624537489435) as an External Account

In your Instaclustr account:

  1. 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.
  2. 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.
  3. 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 support@instaclustr.com to request adding this on your existing cluster.
