Autonomous Database Licensing Models

Understanding the licensing options is crucial for making informed decisions about your Autonomous Database deployment.

ECPU Pricing Metric

Oracle Autonomous Database introduced the new ECPU billing metric in January 2024, with the retirement of the legacy OCPU billing metric for enhanced flexibility and cost optimization.

ECPU (Elastic CPU) is an abstract compute metric of cloud resources that is performance-based, offering several advantages:

• No physical cores or threads dependencies

• Performance-based scaling rather than hardware-constrained

• Future-proof pricing that adapts to hardware evolution

• Simplified capacity planning with elastic characteristics

ECPU Key Features

Available for ADW (Autonomous Data Warehouse) and ATP (Autonomous Transaction Processing), ECPU provides:

Universal Cost Models

• Universal Cost Model (UMC): Standardized pricing across regions and services

• Bring Your Own License (BYOL): Auto-scaling, autonomous data guard, cloning, and other core features are fully supported in both billing metrics

Payment Structures

Oracle Universal Credit payment structure includes:

• Pay As You Go (PAYG): Flexible hourly billing for variable workloads

• Annual Universal Credits: Committed spend programs with volume discounts

• Elastic Pools: Allow you to consolidate autonomous databases into a pool, providing up to 87% compute cost savings

Storage Cost Improvements

ECPU introduction brought significant storage cost reductions: Autonomous Data Warehouse storage price reduced from $118.40 to $25.00 per TB per month, and Autonomous Transaction Processing storage can be provisioned in increments of 1GB with a minimum of 20GB.

Autoscaling with Autonomous Database

Autonomous Database's autoscaling capabilities provide intelligent resource management that optimizes both performance and cost.

CPU and I/O Autoscaling

ADB scales CPU and I/O resources automatically based on workload demands:

• Autoscaling is enabled by default for immediate benefit

• Can be disabled at any time for predictable resource allocation

• Intelligent scaling algorithms based on workload patterns

• Real-time performance monitoring drives scaling decisions

Scaling Parameters

• 3x base number of ECPUs (active): Maximum automatic scaling limit

• ECPUs autoscale back down to base number: Cost optimization during low-demand periods

• Independent scaling: ADB allows you to very easily scale both ECPU and storage independently

Scaling Benefits

• Cost optimization: Pay only for resources actually consumed

• Performance consistency: Maintain response times during demand spikes

• Operational simplicity: No manual intervention required

• Predictable billing: Clear understanding of scaling costs

Oracle ADB Provisioning Process

The provisioning process for Autonomous Database is designed for simplicity while maintaining enterprise-grade capabilities.
