The OCI Architecture Diagram Toolkit is Oracle's official, free set of assets for building professional architecture diagrams. It's the definitive resource for creating documentation that accurately represents your Oracle Cloud Infrastructure (OCI) deployments.
Here is your complete guide to using the official toolkit and modern AI-powered alternatives.
Cloud Architecture
Create cloud architecture diagrams for AWS, Azure, GCP, and more. Design scalable infrastructure with professional cloud icons.
Complete guide to the official OCI Architecture Diagram Toolkit—PowerPoint, draw.io, Visio, SVG/PNG icons—plus AI generators, best practices, and common mistakes.
Click Cloud Architecture to open AI Line Studio and generate diagrams from natural language in seconds.
Oracle offers the toolkit in three core formats to suit different tools and workflows. You can download all of them from the official documentation page.
This is the most comprehensive format, containing the most templates, examples, and service icons. It is ideal for creating polished, presentation-ready diagrams for stakeholders. The .pptx file includes guidance on how to create diagrams for your specific cloud deployment.
This is a favorite among engineers because draw.io is free to use. This template comes pre-loaded with the OCI icon library, allowing you to create diagrams quickly.
For those proficient in Microsoft Visio, this format provides the official OCI stencils and templates.
If you just need the official OCI icons, this is the best resource. It contains all the official service icons in scalable vector (SVG) and portable network graphic (PNG) formats.
AI tools can dramatically accelerate diagram creation, generating a professional layout from a simple text description.
This browser-based, AI-first platform is purpose-built for modern cloud professionals.
How it works:
Key benefits:
MockFlow's AI understands OCI services natively and arranges them with proper VCN structures, fault domain groupings, and Oracle's red color scheme.
How it works:
OCI Icons:
The AI maps plain-language service references to Oracle's official icon library. Mention "database" and it resolves to Autonomous Database; mention "container orchestration" and OKE appears.
VCN Layout:
The AI creates proper VCN containers with grouped subnets, fault domains, and network boundaries. Public, private, and database subnets are all color-coded following Oracle Cloud architecture conventions.
AI Line Studio generates cloud architecture diagrams from natural language descriptions in 15–20 seconds. It supports 3,000+ officially licensed icons across AWS, Azure, GCP, and OCI. The AI cloud diagram generator helps you iterate quickly during design sessions, while the AI architecture diagram builder enables collaborative editing and refinement. For end-to-end system design, the AI system architecture generator creates complete architectures, and the cloud architecture diagram tool provides editable templates with official icons.
Beyond the toolkit, the Oracle Architecture Center is a critical resource for OCI architects. It provides:
Always use the official OCI icons from the toolkit. Using unofficial icons creates confusion and undermines credibility.
Compartments are the primary organizational unit in OCI. Clearly show which resources belong to which compartment and the compartment hierarchy.
OCI network diagrams are incomplete without showing gateways like Internet Gateway, NAT Gateway, Service Gateway, and Dynamic Routing Gateway (DRG).
Include Security Zones, VCN flow logs, OCI Vault and encryption, Security Lists, and Network Security Groups (NSGs).
OCI's fault domain architecture provides anti-affinity. Show which resources are deployed in which fault domains to demonstrate high availability.
A generic "DB" label is not enough. Write "Oracle Autonomous Database" or "OCI Object Storage" to be precise.
