⚙ Full Stack
Kotlin/Spring Boot backend with an embedded SQLite database indexing a filesystem library, plus a Vue.js frontend. Single JVM process handles scanning, thumbnailing, and serving.
📈 Scaling Analysis
Scales vertically only — one JVM process, one SQLite file — which is adequate for personal/family libraries but would need re-architecture (external DB, stateless workers) for a multi-tenant SaaS.
🚀 Running on Nexlayer
Single pod with a persistent volume for the comic library and another for the SQLite index; mirror the JVM base image via mirror.gcr.io. No external services needed for a basic deployment.
