AI Architecture Reference
Visual overview of enterprise AI platforms and how OAIO pillars map to their capabilities. Use these references to communicate how your organization's agent strategy aligns with cloud provider infrastructure.
Why This Matters
AI agents are not just prompts—they require infrastructure for identity, governance, memory, and observability. Major cloud providers have built platform layers specifically for enterprise agent deployment. OAIO helps you prepare your organization to leverage these capabilities effectively, regardless of which platform you choose.

OAIO Pillar Mapping
The five pillars of OAIO are platform-agnostic principles. Here's how they map to specific capabilities in each platform.
OAIO Pillars to Platform Mapping
How each pillar maps to capabilities across all platform options
Platform Selection Considerations
AWS Bedrock AgentCore
- Best for: Custom agent frameworks (LangGraph, CrewAI, Strands)
- Strength: Infrastructure-level control and multi-model flexibility
- Models: Nova, Claude, Llama, Mistral + external via Gateway
- Ideal when: Building custom agents with specific tooling requirements
Microsoft Copilot + Agent 365
- Best for: M365-centric organizations with existing investments
- Strength: Native integration with Office apps and Microsoft Graph
- Data access: Automatic grounding in organizational data
- Ideal when: Extending Copilot with custom agents for business users
Bespoke Agent Stack
- Best for: Maximum control and frontier model access
- Strength: Direct API access to OpenAI, Anthropic, and others
- Trade-off: You build and maintain all governance infrastructure
- Ideal when: Specialized requirements that CSP platforms don't cover
Google Cloud Vertex AI
- Best for: Workspace-centric orgs and multimodal use cases
- Strength: Gemini models + 200+ models via Model Garden
- Data access: Native Workspace integration and enterprise search
- Ideal when: Leveraging Google's AI research and multimodal capabilities
Platform-Agnostic Readiness
OAIO prepares your organization to leverage any AI agent platform. The five pillars ensure you have the value cases, data foundations, governance models, and economic controls in place—regardless of which technology stack you deploy.
Remember: OAIO creates the blueprint—your implementation partner builds the agents.
