Container Resilience Analysis

Shared Testbed for Container Performance & Resilience Research

Repository ini menyediakan infrastruktur pengujian terpadu untuk dua penelitian:

• Paper A (resource-contention-analysis): Analisis resource contention dan CPU throttling pada Single-Host Docker deployment
• Paper B (nginx-spof-mitigation): Evaluasi mitigasi SPOF pada Nginx Reverse Proxy dalam arsitektur kontainer
