Lesson Overview

Today marks your transformation from workflow builder to production deployment expert. You'll learn to take your automations from development to production-ready systems that handle real business load with enterprise-grade reliability.

The Production Mindset

Production Principles:

• Reliability First: Systems must work when it matters

• Scalable Design: Handle growth without breaking

• Observable Operations: Know what's happening always

• Graceful Recovery: Bounce back from failures quickly
