AI in the Cloud: Microsoft Foundry — The Agentic Developer Platform
Microsoft Ignite 2025 introduced Foundry, and it's positioned to be the central hub for building AI agents on Azure.
What Is Microsoft Foundry?
Think of it as the unified platform for everything agentic AI on Azure:
1. Unified MCP Tool Catalogue
The Model Context Protocol (MCP) finally gets a proper home. Foundry provides a catalogue of MCP-compatible tools that any AI agent can discover and use. No more reinventing integrations for every project.
2. Foundry Agent Service
A hosted multi-agent runtime with built-in memory. Deploy agents that can:
- •Maintain conversation state across sessions
- •Coordinate with other agents
- •Access enterprise data securely
3. Foundry Control Plane
Enterprise-grade observability and governance. This is where IT and security teams get visibility into what agents are doing, what data they're accessing, and how to enforce policies.
The Scale Is Impressive:
Azure now hosts over 11,000 models. Whether you want Claude, Gemini, Llama, or proprietary models — they're all accessible through the same platform.
Why This Matters for Cloud Engineers:
The agentic AI pattern is moving from experimentation to production. Foundry provides:
- •Standardization: MCP means your tools work across different AI models
- •Governance: Control Plane means you can actually deploy agents in regulated environments
- •Scalability: Azure's infrastructure handles the compute complexity
The Bigger Picture:
Microsoft, Anthropic, and NVIDIA just announced a massive partnership — $30B from Anthropic for Azure compute, $5B from Microsoft, $10B from NVIDIA invested in Anthropic.
Foundry is the platform that makes this partnership practical. Build once, deploy anywhere in the Azure ecosystem.
Getting Started:
- 1Explore Azure AI Foundry in the portal
- 2Check out the MCP tool catalogue
- 3Start with a single-agent prototype before scaling to multi-agent
The agentic era isn't coming. It's here.
