Level 6: The Component Catalog
The infrastructure building blocks every senior engineer should be able to reason about and evaluate.
Welcome to Level 6
Senior engineers do not just know databases and caches. They know the full catalog of infrastructure components that modern systems are built from. Each module in this level is a deep dive into one component category.
What you will learn
| Module | Topic |
|---|---|
| 6.1 | Containers and Orchestration (Docker, Kubernetes) |
| 6.2 | Object and Blob Storage (S3, GCS) |
| 6.3 | Search Infrastructure (Elasticsearch) |
| 6.4 | Task Queues and Job Scheduling |
| 6.5 | Notification Infrastructure |
| 6.6 | Logging and Monitoring Pipelines |
| 6.7 | Payment and Billing Systems |
| 6.8 | Feature Flags and A/B Testing |
| 6.9 | Checkpoint |
Key Takeaway
Knowing the component catalog lets you quickly assemble architectures from proven building blocks instead of reinventing solutions. Each component has established patterns, common pitfalls, and decision criteria.
