Apache Cassandra is an open-source NoSQL database. It scales linearly, and data is replicated automatically to multiple nodes. Run your Apache Cassandra clusters in Oracle Cloud Infrastructure, and take advantage of enterprise-grade reliability, security, and operational flexibility.

For details of the architecture, see Deploy a highly available Apache Cassandra cluster

Prerequisites

• Permission to manage the following types of resources in your Oracle Cloud Infrastructure tenancy: vcns, internet-gateways, route-tables, security-lists, subnets, and instances.

• Quota to create the following resources: 1 VCN, 1 subnet, 1 Internet Gateway, 1 NAT Gateway, 1 route rules, and 6 compute instances (Cassandra nodes).

If you don't have the required permissions and quota, contact your tenancy administrator. See Policy Reference, Service Limits, Compartment Quotas.

Deploy Using Oracle Resource Manager

1. Click

   If you aren't already signed in, when prompted, enter the tenancy and user credentials.

2. Review and accept the terms and conditions.

3. Select the region where you want to deploy the stack.

4. Follow the on-screen prompts and instructions to create the stack.

5. After creating the stack, click Terraform Actions, and select Plan.

6. Wait for the job to be completed, and review the plan.

   To make any changes, return to the Stack Details page, click Edit Stack, and make the required changes. Then, run the Plan action again.

7. If no further changes are necessary, return to the Stack Details page, click Terraform Actions, and select Apply.

Deploy Using the Terraform CLI

Clone the Module

Now, you'll want a local copy of this repo. You can make that with the commands:

git clone https://github.com/oracle-quickstart/oci-arch-cassandra.git
cd oci-arch-cassandra
ls

Set Up and Configure Terraform

1. Complete the prerequisites described here.

2. Rename provider.tf.cli to provider.tf

3. Create a terraform.tfvars file, and specify the following variables:

# Authentication
tenancy_ocid         = "<tenancy_ocid>"
user_ocid            = "<user_ocid>"
fingerprint          = "<finger_print>"
private_key_path     = "<pem_private_key_path>"

# Region
region = "<oci_region>"

# Compartment
compartment_ocid = "<compartment_ocid>"

Create the Resources

Run the following commands:

terraform init
terraform plan
terraform apply

Destroy the Deployment

When you no longer need the deployment, you can run this command to destroy the resources:

terraform destroy
