System Design & Scaling Guide

Master architectural thinking for AI systems: scaling strategies, reliability patterns, integration patterns (webhooks, event-driven, MCP), real-world channels (Slack/Discord), and performance vs cost trade-offs. This synthesis guide connects everything you've learned—Docker, CI/CD, deployment, monitoring, cost optimization, security—and teaches you to DESIGN production-ready systems. Culminates with the complete architecture design for the Capstone: AI-Powered Knowledge Assistant with Agentic RAG and Slack/Discord integration.

Outcomes

What you'll be able to do

  • Apply architectural thinking specific to AI systems (constraints, trade-offs, design documents)
  • Compare and choose between monolith, microservices, and event-driven architectures for AI
  • Design scaling strategies: horizontal vs vertical, auto-scaling, stateless design
  • Implement integration patterns: webhooks, event-driven, MCP (Model Context Protocol)
  • Design reliability at scale: load balancing, queue-based processing, rate limiting
  • Design Slack and Discord bots as production channels (OAuth, webhooks, best practices)
  • Apply decision frameworks for performance vs cost, managed vs self-hosted, cache vs compute
  • Design the complete architecture for the Capstone: AI-Powered Knowledge Assistant

Before you start
