Oracle Autonomous Database Deployment Options: Serverless vs Dedicated Infrastructure

Oracle Autonomous Database offers flexible deployment choices designed to meet diverse organizational requirements, from fully managed serverless deployments to dedicated infrastructure with maximum control and isolation. Understanding these deployment options is crucial for optimizing performance, security, and operational efficiency.

Understanding Deployment Choices

Oracle Autonomous Database provides two primary deployment models, each designed for specific use cases and organizational needs:

Complete Oracle Automation:
In the serverless model, Oracle manages and automates the entire database infrastructure stack, enabling organizations to focus exclusively on application development and data management.

Key Characteristics:

  • Zero Infrastructure Management: Oracle handles all infrastructure operations
  • Automatic Scaling: Dynamic resource allocation based on workload demands
  • Shared Infrastructure: Cost-efficient multi-tenant architecture
  • Rapid Provisioning: Instant database deployment in minutes
  • Pay-Per-Use Pricing: Consumption-based billing model

Ideal Use Cases:

  • Development and testing environments
  • Applications with variable workload patterns
  • Organizations seeking minimal operational overhead
  • Quick proof-of-concept deployments
  • Cost-sensitive workloads

Dedicated Infrastructure Deployment

Customer-Controlled Private Database Cloud:
Autonomous Database on Dedicated Exadata Infrastructure enables customers to provision autonomous databases into their own dedicated Exadata cloud infrastructure, providing customization over operational policies.

Deployment Locations:

  • Oracle Public Cloud: Dedicated Exadata infrastructure within OCI regions
  • Cloud@Customer: On-premises deployment with cloud management
  • Multicloud: Deployment in AWS and Azure cloud regions

Benefits of Autonomous Database Dedicated

Private Database Cloud Architecture

Dedicated Exadata Infrastructure:
Organizations get a completely dedicated compute, storage, network, and database service, providing the highest security, isolation, and governance levels.

Infrastructure Isolation:
Your own private database cloud running on dedicated Exadata infrastructure ensures complete resource isolation from other tenants.

Customizable Operational Policies:

  • Maintenance Windows: Define custom maintenance schedules
  • Database Versions: Control database version upgrades

Multiple Isolation Levels

Autonomous Database Dedicated provides comprehensive isolation at multiple architectural layers:

1. Autonomous Database Level:
Individual database instances with dedicated resources and isolated workload management.

2. Autonomous Container Database (ACD):
Logical container providing multi-tenancy capabilities while maintaining isolation between database groups.

3. Autonomous VM Cluster (AVMC):
Dedicated virtual machine cluster providing compute and memory isolation.

4. Separate Hardware (Exadata Infrastructure):
Physical infrastructure isolation with dedicated Exadata servers, storage, and networking.

5. Network Isolation:

  • Virtual Cloud Network (VCN): Dedicated network infrastructure
  • Private Subnets: No public internet access to databases
  • Private Endpoints: Secure connectivity without public exposure

Shared Responsibility Model

Customer Responsibilities:

  • Data Schemas: Application schema design and management
