A curated collection of visual representations and diagrams to help prepare for technical interviews, focusing on core concepts in cloud computing, containerization, and distributed systems.
This repository consolidates visual representations of complex technical concepts that are frequently asked about in technical interviews. Each diagram is designed to be:
- Interview-ready: Clear, concise, and easy to explain
- Comprehensive: Covers the complete flow or architecture
- Accurate: Based on current best practices and standards
- Memorable: Uses visual cues and color coding for easy recall
