1. Foundations of DNS, HTTP & TLS
Getting Started with DNS, HTTP & TLS
The protocols that power the web. How DNS resolves names, how HTTP requests work, and how TLS encrypts them. To build stable, high-performance systems, you need a firm grasp of the fundamental concepts that govern DNS, HTTP & TLS.
🏗️ Architectural Design
Every technology has a core set of components. For DNS, HTTP & TLS, understanding the interaction between data states, configurations, and environment resources is critical to writing maintainable workflows.
- Component Isolation: Keep parts separate to make debugging simple.
- Configuration Management: Avoid hardcoded variables; use environment variables.
- Continuous Integration: Integrate early and build pipelines to verify reliability automatically.
