Microsoft has wrapped up its Agent Factory blog series with a bold blueprint for what it calls the "agentic web stack," a framework designed to power the next era of intelligent, autonomous software agents. The company sees this stack as a critical foundation for enterprises looking to build, scale, and govern AI-driven multi-agent systems across industries.

The Rise of Enterprise AI Agents

AI agents—autonomous systems capable of performing tasks, collaborating, and making decisions on behalf of users—are moving from research prototypes to production-grade enterprise tools. Microsoft argues that creating effective agents requires more than strong models or clever code. It demands a standardized and interoperable blueprint spanning design patterns, developer tooling, security, observability, governance, and integrations.

Throughout the Agent Factory series, Microsoft walked enterprises through each layer of this journey—from early use cases and developer workflows to governance models and interoperability standards. Now, it's final post zooms out to paint the bigger picture: a shared agentic web stack, as fundamental to AI agents as HTTP and TCP/IP were to the internet.

Eight Core Pillars of the Agentic Web Stack

The Microsoft Azure AI Foundry team outlined eight essential elements required to build an open, secure, and scalable ecosystem for multi-agent systems:

• Communication Protocols: Standards like the Model Context Protocol (MCP) and Agent-to-Agent (A2A) unlock collaboration between agents, whether within one company or across supply chains. Azure AI Foundry integrates A2A to enable cross-enterprise workflows securely.

• Discovery and Registry Services: Much like search engines power the web, catalogs and registries allow agents, APIs, and tools to be discovered, tracked, and reliably orchestrated in real-world environments.

• Identity and Trust: Verified identity standards (OIDC, JWT) combined with Microsoft Entra ID bring a zero-trust security model to agents, giving enterprises fine-grained control, accountability, and compliance-by-design.

• Tool Integration via MCP: Agents can instantly connect to enterprise APIs registered once in Azure AI Foundry, making interoperability seamless across frameworks such as Semantic Kernel, AutoGen, LangGraph, and more.

• Multi-Agent Orchestration: Real breakthroughs occur when multiple agents collaborate on distributed tasks, from financial processing to IT incident response. Azure AI Foundry offers orchestration services that handle dependencies, conflicts, and governance.

• Observability and Telemetry: Extending OpenTelemetry, Azure Foundry enables real-time tracing of conversations, performance monitoring, and end-to-end transparency for audits and compliance.

• Memory Systems: With both short-term and long-term memory, agents move from transactional workers to adaptive strategic partners—like remembering past customer complaints or supply chain disruptions to improve future operations.

• Evaluation and Governance: In-built governance hooks ensure compliance, safety, and ethical boundaries through continuous evaluation, audit trails, and controlled approvals for sensitive workflows.

Real-World Enterprise Benefits

Microsoft highlighted how this foundational stack translates into tangible business value:

• End-to-End Process Automation: From procurement to payments, multiple agents collaborate to slash cycle times from weeks to hours.

• Cross-Border Supply Chains: Agents securely interoperate across companies, reducing delays at customs and improving logistics coordination.

• Knowledge Worker Augmentation: Agents handle repetitive, high-value tasks, while memory capabilities keep them context-aware across workflows.

• Complex IT Operations: Multi-agent workflows detect, diagnose, and resolve outages with speed, while observability ensures compliance.

• Adaptive Customer Journeys: Personalized, memory-driven support agents transform customer relationships by blending efficiency with trust.

Strategy for the Agentic Era

Microsoft recommends organizations prepare now by:

• Embracing open standards like MCP and A2A to future-proof deployments.

• Prioritizing identity, observability, and memory as non-negotiable pillars.

• Operationalizing governance early to scale AI adoption responsibly.

• Actively contributing to open-source and standards communities.

• Training employees to collaborate and supervise AI agents, not just use them.

Looking Ahead: Ignite 2025

The vision behind the Agent Factory series will take center stage at Microsoft Ignite 2025, where Azure will showcase new innovations, deeper enterprise integrations, and advanced multi-agent orchestration capabilities.
