Semantic Kernel (Legacy)

• Key points are in the visual diagram above.

Enterprise teams need a production-grade framework that integrates with existing Microsoft ecosystems (Azure OpenAI, Cosmos DB, Entra ID) while supporting multiple languages (.NET, Python, Java). Semantic Kernel provides the plugin architecture, planning, and memory abstractions for enterprise agent development.

Semantic Kernel is like an enterprise service bus for AI — it connects LLMs to your existing systems through standardized plugins, with the governance and integration patterns enterprises require.

Scenario

Enterprise HR bot on Semantic Kernel: user asks about benefits → planner selects BenefitsPlugin → native function queries HR database → semantic plugin formats response → responsible AI filter checks output → Entra ID validates user access → response with telemetry logged.

Solution

In Agent Framework Landscape, apply Semantic Kernel (Legacy) to this scenario: Enterprise HR bot on Semantic Kernel: user asks about benefits → planner selects BenefitsPlugin → native function queries HR database → semantic plugin formats response → responsible AI filter checks output → Entra ID validates user access → response with telemetry logged. Identify the inputs, run the technique, validate the output, and note one thing you would monitor in production.

Do this before moving to the next module — reading alone is not enough.

Open the Code Walkthrough below and run it locally. Change one parameter related to Semantic Kernel (Legacy) (e.g. model, temperature, top_k, or tool name), observe the difference in output, and write 2–3 sentences explaining what changed.

• Only semantic plugins — missing native code integration
• No responsible AI filters in production
• Ignoring Process Framework for long-running tasks
• Not leveraging Entra ID for enterprise auth
• Using SK without Azure integration — loses key benefits

Quick recap — the most important points from this module.
