SLIDE 2: What You Will Learn
Course Coverage
Production Architecture Decisions:
- How production constraints change your design choices
-Service boundaries, ownership, and API contracts
-Sync vs async patterns and when to use each
-Data schemas that can evolve without downtime
-Caching and queue patterns that survive failure
-Deployment strategies that do not wake you at 3am
Reliability and Operations:
- Failure handling: timeouts, retries, circuit breakers
-Observability that helps you debug, not drown in alerts
-Incident response and postmortem culture
-Cost-aware architecture decisions

Production systems are never “done.” They evolve continuously.
SLIDE 3B: The Gap: Interview vs Production (continued)
What Interviews Test vs What Production Requires:
The Question This Course Answers:
You know how to design systems on a whiteboard. This course teaches you how to design systems that do not page you at 3am.
SLIDE 4: Who This Course Is For
Target Audience
This Course Is For You If:
- You can pass a system design interview but have never operated a system at scale
- You have built systems but want to understand production patterns formally
- You are preparing for senior or staff level interviews where production experience matters
- You want to understand why your oncall keeps paging you
Prerequisites:
- Basic understanding of system design concepts (databases, caching, load balancing)
- Familiarity with at least one backend programming language
- Ideally: have watched or understand content similar to the Instagram System Design course
Not Covered:
- Basic system design concepts (this is not an intro course)
- Language-specific implementation details
- Cloud provider specific configurations (concepts apply to AWS, Azure, GCP)

These Constraints Shape Every Decision:
- Uptime SLA: 99.9% means 8.7 hours downtime per year maximum
- Latency Budget: P99 under 500ms across all dependencies
- Cost Ceiling: Infrastructure budget is finite
- Team Size: 5 engineers cannot operate 50 microservices
- Compliance: GDPR, SOC2, HIPAA restrict architecture choices
Key Insight:
In interviews, you optimize for elegance. In production, you optimize for constraints.
