Understand the Life Cycle of Oracle Big Data Cloud Service

For each Oracle Big Data Cloud Service cluster you want to create, you must have a separate subscription.

The process is as follows:

  1. Purchase a subscription. Go to cloud.oracle.com or contact an Oracle Sales Representative to buy a subscription. See How to Begin with Oracle Big Data Cloud Service.

    Every cluster must have at least three permanent Hadoop nodes (a starter pack) and can have an additional 57 permanent nodes, which can be a combination of permanent Hadoop nodes and edge nodes. When you purchase your subscription, make sure to include enough resources to create a cluster or clusters with the number of nodes you want to have initially.

    After you’ve created a cluster, you can extend your subscription with additional permanent nodes, up to the maximum 60.

  2. If this is a new Oracle Cloud account, provide account details, such as account name and administrator details.

  3. Create a service instance. This step allocates the resources for a cluster. A cluster must have one and only one starter pack of 3 permanent nodes and can have up to 57 additional nodes (for a total of 60 permanent nodes), so you must create an instance with the number of nodes you initially want for your cluster. The minimum is the three –node starter pack, but at least five nodes are recommended for production environments. Creating an instance doesn’t create the cluster itself. See Create an Oracle Big Data Cloud Service Instance.

  4. Create the cluster. You can have only one cluster per service instance. See Create a Cluster.

  5. After the cluster is created, you can extend it in two ways:

  6. If needed, you can delete the cluster and create a new one, using the resources specified in your subscription and allocated to the service instance. In this case, you don’t have to create a new service instance before creating the cluster. Because the resources are already allocated, you can create the cluster directly.

The above steps are similar to the steps for other Oracle Cloud services, but each service has its own variations. For generic instructions on subscribing to a service and instantiating it, see Getting Started with Oracle Cloud.


If you’ve included the Oracle Big Data SQL Cloud Service add-on in your subscriptions, there are a few additional steps. See Use Oracle Big Data SQL Cloud Service with Oracle Big Data Cloud Service
