Creating a PCI Compliant Cassandra Cluster


The PCI compliance standards relate to the security of user data and transactional information. You can read more about PCI and our support for it here.

In order to create a new cluster compliant with PCI standards, there are several steps that are required:

  1. Enable PCI Compliant account security settings
  2. Selecting Cassandra as the base bundle
  3. Include the PCI add-ons
  4. Select the AWS provider
  5. Configure any other cluster attributes
  6. Start cluster provisioning

Creating a cluster

  1. Heading over to the security tab in your account settings, select the “PCI Compliant Account” box at the top. PCI compliance relies on multi-user access, as such we recommend having 2 account owners in case of loss of access for one person. This satisfies the first section of the PCI requirements. From here, enable the ‘PCI compliance mode’ checkbox. This allows you to access the requirements for using PCI with a cluster. ROUTE NOTE: From here on out you can continue with the Console interface to finish the PCI compliant cluster provisioning or alternatively you can continue with the API from here to finish the PCI compliant cluster provisioning.
  2. Moving back to the Create Cluster page, enter an appropriate name for your cluster (it cannot be changed after cluster creation), choose a cluster configuration matching your performance and pricing requirements. Note: Instaclustr recommends that cluster nodes are allocated across different racks within a data centre and that the allocation be evenly distributed. This ensures stability, fault-tolerance and consistent performance.
  3. Under the Applications section, select the Cassandra base application and choose the PCI add-on. Additionally, choose any other add-ons you require for this cluster.
    Note: Certain add-ons are not PCI compliance, see here for more information.
  4. Under the Data Centre section, choose the AWS provider, Region, Custom Name (which is a logical name for the data centre within Cassandra), Data Center Network address block, Node Size, EBS Encryption option, Replication Factor and number of nodes. Refer to our support article on Network Address Allocation to understand how we divide up the specified network range to determine the node IP addresses.
  5. Under [Cassandra Options] section, select your Network and Security settings.

    NOTE: Ensure you have the “add xx.xx.xx.xx to cluster firewall allowed addresses” option ticked, this will allow your computers IP to connect with the cluster. Certain web proxies may interfere with this mechanism and Instaclustr will see their IP address instead. We suggest you verify the detected address.
  6. Select SLA Tier you want to tag your cluster with. Non-production clusters may receive lower priority support and reduced SLAs. Production tier is not available when using Developer class nodes. You can find more information here.
  7. The Summary section displays a brief summary of your cluster configurations and pricing details. Click the Terms and Conditions link to open the Instaclustr Terms and Conditions and other policy documents. After going through the document, select the checkbox to accept the Terms and Conditions. Once you are happy with the cluster configuration and have accepted the terms and conditions, click the Create Cluster button to start creating the cluster.

    NOTE: Your cluster will be placed in a deferred state if you have not specified your payment details, if you have not already done so please follow the blue banner to update your payment details.

    Once you have confirmed your details, your cluster will begin provisioning.

By enabling a PCI cluster, our security team will get in contact with you to complete additional steps related to PCI onboarding. We recommend reviewing the following support articles as a next step

  • Connecting to your cluster
  • Connecting to your cluster using CQLSH

Contact us at if there is any issue in provisioning your cluster.
