Autonomous Database

Autonomous Database is a fully managed Oracle Database that uses machine learning to automate routine tasks:

Self-Driving

• Auto-tuning — automatically optimises queries and indexes
• Auto-scaling — scales compute and storage based on demand
• Auto-patching — applies patches and updates with zero downtime

Self-Securing

• Auto-encryption — data encrypted at rest and in transit (always on, cannot be disabled)
• Auto-security patches — applied automatically without downtime
• Data Safe — built-in data security assessment and masking

Self-Repairing

• Auto-backup — continuous automatic backups
• Auto-failover — automatic failover in case of failure
• 99.995% SLA — with Autonomous Data Guard

Autonomous Database Workload Types

Workload	Optimised For	Use Case
Autonomous Transaction Processing (ATP)	OLTP, mixed workloads	Applications, microservices
Autonomous Data Warehouse (ADW)	Analytics, data warehousing	BI, reporting, data science
Autonomous JSON Database	JSON document storage	APIs, document workloads
APEX Application Development	Low-code apps	Rapid application development

All workload types use the same underlying Oracle Database technology.

Deployment Options

Option	Description
Serverless	Shared infrastructure, scales automatically (most common)
Dedicated	Isolated Exadata infrastructure for your exclusive use
Cloud@Customer	Autonomous Database in your own data centre

Serverless OCPU Scaling

• Base OCPUs — minimum compute always available
• Auto-scaling — up to 3x the base OCPUs when demand increases
• Scale to zero — stop compute when not in use (storage remains)

For workloads that need full control over Oracle Database:

DB Systems

Type	Description
VM DB System	Oracle Database on virtual machines
Bare Metal DB System	Oracle Database on dedicated bare metal servers
Exadata DB System	Oracle Database on Exadata hardware (highest performance)

Exadata Cloud Service

OCI's highest-performance database platform:
