8. Scaling & Operations
Production Readiness & Scaling
Combine architecture, security, observability, recovery and capacity into a production operating system.
Lesson overview
Production readiness is an operating loop: deploy, observe, detect, mitigate, recover, learn and improve. Scaling can mean better queries, caching, workers, replicas or additional instances depending on the measured bottleneck.

Step 1
Theory
Production readiness is an operating loop: deploy, observe, detect, mitigate, recover, learn and improve. Scaling can mean better queries, caching, workers, replicas or additional instances depending on the measured bottleneck.
Step 2
Example
A final readiness review should cover rollback, security, observability, recovery, capacity, dependencies, ownership and incident procedures.

Step 4
Practice
Review your current application and apply Production Readiness & Scaling. Document the current behavior, one production risk, the change you would make, and how you would verify it.
Step 5
Quiz
1. What is the central production concern in "Production Readiness & Scaling"?
Step 6
Challenge
Design a production-ready implementation for Production Readiness & Scaling. Include failure handling, security considerations, observability, testing and a rollback or recovery path where applicable.
