Oracle Autonomous Database Dedicated: Fleet Administration, Provisioning, and Role-Based Management

Oracle Autonomous Database on Dedicated Exadata Infrastructure enables organizations to build private database clouds with self-service capabilities while maintaining centralized governance and control. Understanding the fleet administration model, provisioning workflows, and role-based access control is essential for successfully deploying and managing dedicated autonomous database environments.

Fleet Administrator Role and Responsibilities

Core Fleet Administrator Functions

As fleet administrator, you set up your dedicated ADB platform in OCI and on Exadata Cloud@Customer, serving as the central point of control for infrastructure provisioning and management.

Infrastructure Provisioning:
The Fleet Administrator provisions Exadata Infrastructure by specifying its size, availability domain, and region, establishing the foundation for the private database cloud.

System Partitioning:
Fleet Administrators partition the system by provisioning Autonomous VM Clusters (AVMC) and Autonomous Container Databases (ACD), creating logical boundaries for different organizational units or workload types.

Key Responsibilities:

• Capacity Management: Monitor and allocate infrastructure resources
• Budget Control: Manage costs and spending across the fleet
• Compatibility Management: Control database versions and feature adoption
• Service Level Agreements: Define and enforce SLAs for database services
• Infrastructure Lifecycle: Plan and execute infrastructure upgrades and maintenance

Self-Service Database Provisioning Model

Developer and DBA Access:
Developers, DBAs, and end users provision databases within Autonomous Container Databases using self-service tools, enabling rapid database deployment without fleet administrator intervention.

Self-Service Capabilities:

• Database Creation: Instant provisioning of new autonomous databases
• Monitoring: Real-time performance and health monitoring
• Management: Day-to-day database operations and administration
• Scaling: Dynamic resource allocation adjustments
• Backup/Recovery: Self-service backup and restore operations

Billing and Cost Model

Autonomous Database Dedicated Pricing Structure

Infrastructure-Based Billing:
Billing is based on the size of Exadata infrastructure and the number of active ECPUs (Elastic CPUs) used by databases, providing predictable cost management.

ECPU Billing Metric:
Since January 2024, Oracle retired the OCPU billing metric in favor of ECPUs, providing more granular scaling and cost optimization. ECPU billing provides 50% lower entry cost with the smallest Autonomous Database being significantly less expensive than previous OCPU-based pricing.

Zero-Cost Resource Provisioning:
Organizations incur zero costs for resource provisioning activities like AVMC and ACD provisioning—costs are only incurred when databases actively consume compute resources.

Cost Optimization Benefits:

• Pay for Active Consumption: Only active database ECPUs incur charges
• Granular Scaling: Finer increments for resource allocation
• Predictable Costs: Infrastructure-level pricing provides budget predictability
• No Overhead Charges: Logical containers (AVMC, ACD) have no separate fees

Getting Started: Private Cloud Setup

Initial Setup Prerequisites

Provisioning Dedicated Resources: Step-by-Step

Step 1: Create Virtual Cloud Network (VCN)

Network Foundation:
To get started with Autonomous Database on Dedicated Exadata Infrastructure, the fleet administrator must create the core infrastructure resources and institute access controls to ensure that only authorized personnel and applications have network access.

VCN Configuration:

• CIDR Block: Define IP address range for your private cloud
• Subnets: Create private subnets for database resources
• Security Lists: Configure ingress and egress rules
• Route Tables: Define routing for traffic flow
• Network Security Groups: Implement fine-grained access control

Security Considerations:

• Use private subnets to eliminate public internet exposure

OCI Policies for Autonomous Dedicated

Role-Based Access Control Architecture

Identity and Access Management (IAM) Foundation:
Implement separation of duties between fleet administrators and database users through OCI's identity and access management system.

Core IAM Concepts:

Groups:
A set of users with the same privileges and access requirements. Groups enable consistent policy application across multiple users.

Policies:
Bind privileges for a group to a specific set of resources in a compartment, defining what actions group members can perform on which resources.

Compartments:
An operating context for a specific set of service resources, accessible only to groups who are explicitly granted access. Compartments provide resource isolation and access control boundaries.
