Striae Origins, Episode 2: The Evolution of Striae's Architecture
Stephen Lu discusses the evolution of Striae's architecture, emphasizing security, forensic integrity, and edge-first design principles. He shares insights into building a cloud-native forensic platform with layered security, modular workers, and a thin UI, highlighting the importance of constraints and principles in architecture.
Key Topics
Architecture evolution from paper sketch to multi-worker platform
Security layering and cryptographic signing
Separation of concerns for forensic evidence integrity
Edge-first deployment with Cloudflare workers
Incremental development: UI first, backend later
Additional concerns: PDF generation, audit logging, key management
