Goal: design for failure — high availability, disaster recovery, containerized deployment patterns, and the ideas behind infrastructure as code.

Modules

1. High Availability Concepts (redundancy, failover, health checks)
2. DNS & Load Balancer HA Patterns
3. Backup & Disaster Recovery Strategy
4. Containerization Basics (Docker) as a Deployment Pattern
5. Infrastructure as Code Overview
6. Configuration Drift & Idempotency
7. Service Mesh & Internal Networking Concepts
8. Chaos Engineering Basics
9. Observability at Scale (metrics, logs, traces)
10. Capstone — Highly Available Web Service Design

Work through the modules in order — HA concepts and DNS/LB patterns set up the vocabulary, backups and IaC give you the tools to rebuild and recover, and the capstone has you design a full highly-available web service from the primitives covered along the way.
