Getting Started

Learn how to get started with Big Data Service clusters.

Before you create and use Big Data Service clusters in a new account, review the following information and all prerequisites and required tasks.

When you sign up for Oracle Cloud Infrastructure (OCI), Oracle creates a tenancy for the account. The tenancy is a secure and isolated partition within OCI where you can create, organize, and administer your cloud resources.

Big Data Service uses Identity and Access Management (IAM) for authentication and authorization through OCI. Create IAM users, groups, and policies to control access to resources used in your Big Data Service environment. Manage authentication and authorization to Big Data Service by using OCI services and by using Linux OS services and accounts.

To set up access controls for Big Data Service through IAM, an administrator must:

  • Optionally create compartments in the tenancy to organize and isolate resources and services.

  • Configure the Virtual Cloud Network (VCN) for the service including subnets and network resources. Network access rules control access to the network and resources on the network.

  • Create groups and add users to the group. At a minimum, create an administrators group and a users group.

  • Create policies to control access. Policies can be written, for example, to say which groups can perform what actions on which resources in which compartments.

Note

Every tenancy has one or more users in the Administrators group. These users are cloud administrators and can perform the preceding actions, even if no administrator is defined for Big Data Service.

For information about users, groups, and policies defined through IAM, see Overview of Oracle Cloud Infrastructure Identity and Access Management and subsequent topics.
