About Big Data Cloud Clusters on Oracle Cloud Infrastructure

You can create Oracle Big Data Cloud clusters on Oracle Cloud Infrastructure and on Oracle Cloud Infrastructure Classic.

The infrastructure a cluster gets created on depends on the region you select when you create the cluster. If you see the Availability Domain and Subnet fields when you select a region for the cluster you're creating, that means the cluster will be created on Oracle Cloud Infrastructure. Otherwise, the cluster is created on Oracle Cloud Infrastructure Classic.

To determine which infrastructure your cluster is running on after the cluster has been created, click the Instance Details icon for the cluster, and then locate the Region information. If the value is us-phoenix-1, us-ashburn-1, eu-frankfurt-1, or uk-london-1, then the instance is running on Oracle Cloud Infrastructure.

Prerequisites on Oracle Cloud Infrastructure

Oracle Big Data Cloud clusters on Oracle Cloud Infrastructure require certain networking and storage resources that you must create on Oracle Cloud Infrastructure before you create your first cluster.

To learn about these resources, see Prerequisites for Oracle Platform Services in the Oracle Cloud Infrastructure documentation.

For step-by-step instructions to create these resources, see Creating the Infrastructure Resources Required for Oracle Platform Services.

Note:

Oracle Big Data Cloud uses the native Oracle Cloud Infrastructure object storage API rather than the Swift API. As such, an API signing key is required for authentication to Oracle Cloud Infrastructure Object Storage, not a Swift user name and password as described in the Prerequisites documentation above.

Differences Between Clusters on Oracle Cloud Infrastructure and Oracle Cloud Infrastructure Classic

The cluster environment on either type of infrastructure is substantially the same. A few differences exist in the underlying infrastructure components and in the supported capabilities. Awareness of these differences will help you choose an appropriate infrastructure when creating a cluster.

The following table lists differences between Big Data Cloud clusters on Oracle Cloud Infrastructure and on Oracle Cloud Infrastructure Classic.

Feature	Oracle Cloud Infrastructure Classic	Oracle Cloud Infrastructure
Availability domains	Not applicable	Each region has multiple isolated availability domains, with separate power and cooling. The availability domains within a region are interconnected using a low-latency network. When creating a cluster, you can select the availability domain that the cluster should be placed in.
Subnets and IP networks	You can attach clusters to IP networks defined on Oracle Cloud Infrastructure Compute Classic.	You must attach each cluster to a subnet, which is a part of a virtual cloud network that you create on Oracle Cloud Infrastructure.
Compute shapes	Standard and high memory shapes The list of available shapes may vary by region. For information about shapes, see About Shapes in Using Oracle Cloud Infrastructure Compute Classic.	VM.Standard and BM.Standard shapes The list of available shapes may vary by region. For information about shapes, see Overview of the Compute Service in the Oracle Cloud Infrastructure documentation.
IP reservations	Not supported	Not supported
Network access to clusters	Use the Oracle Big Data Cloud interfaces to configure access rules. Note that these access rules prohibit access by default (with the exception of SSH access on port 22), and you must enable them to provide access to other ports.	Use Oracle Cloud Infrastructure interfaces to configure security rules.
Scaling clusters	Supported	Not supported You cannot scale the shape of a cluster’s compute nodes; you can scale only the storage. The minimum size of a new storage volume on Oracle Cloud Infrastructure is 50 GB.
Using Oracle Identity Cloud Service to control access to applications deployed on the cluster	In accounts that use Oracle Identity Cloud Service, while creating a cluster, you can enable Oracle Identity Cloud Service as the identity provider for applications deployed on the cluster.	Not supported
Load balancer options	While creating a cluster, if you enable Oracle Identity Cloud Service as the identity provider, an Oracle-managed load balancer is created and configured automatically for the cluster. If you don’t enable Oracle Identity Cloud Service, then you can use Oracle Traffic Director.	Uses a custom load balancer.
Object storage	You can create the object storage container either before or during cluster creation.	You must create the object storage bucket on Oracle Cloud Infrastructure before creating the cluster.
