Agents

Most agent demos die in production. Here’s a practitioner’s playbook for designing LLM agents that are observable, testable, and actually ship.

Most LLM agent demos die in production because teams skip the boring parts: tool contracts, eval harnesses, and observability. This post walks through the architecture, patterns, and evaluation loops that turn a clever prototype into a system you can actually operate.

Table of Contents Introduction What Is an “Agent” in Computing? From Stand‑Alone Bots to Agents as a Service (AaaS) Core Architectural Components of AaaS Deployment Models: Cloud, Edge, and Hybrid Real‑World Use Cases 6.1 Customer‑Facing Conversational Agents 6.2 DevOps & Infrastructure Automation 6.3 Personal Knowledge & Productivity Assistants 6.4 IoT & Industrial Automation 6.5 Financial Services & Risk Management Building a Simple Agent Service – A Step‑by‑Step Example Scaling the Service: Container Orchestration & Serverless Patterns Benefits of AaaS Challenges and Mitigation Strategies AaaS vs. Traditional SaaS / PaaS Future Directions: LLM‑Powered Agents and Autonomous Orchestration Best Practices Checklist Conclusion Resources Introduction The term “Agent as a Service” (AaaS) has started to appear in cloud‑native roadmaps, AI strategy decks, and developer forums alike. At its core, AaaS is the packaging of autonomous, goal‑oriented software entities—agents—into a consumable, multi‑tenant service that can be invoked via APIs, event streams, or messaging queues. ...

No longer confined to narrow, task‑specific tools, AI agents—software entities capable of perceiving, reasoning, and acting autonomously—are now integral components of everything from self‑driving trucks to personalized health coaches. This guide provides a deep dive into the technological foundations, architectural patterns, real‑world deployments, and emerging ethical questions that define the autonomous systems landscape today. ...

Introduction Tool calling (also called function calling or plugins) is the capability that turns large language models from text predictors into general-purpose controllers for software. Instead of only generating natural language, an LLM can: Decide when to call a tool (e.g., “get_weather”, “run_sql_query”) Decide which tool to call Construct arguments for that tool Use the result of the tool to continue its reasoning or response This post is a deep dive into the anatomy of tool calling: the moving parts, how they interact, what can go wrong, and how to design reliable systems on top of them. ...
