Renovator: Resilience System in Microservices Architecture Using Fault Tolerance Factor
Sari
ABSTRAK
Arsitektur microservices menghadapi tantangan dalam menjaga ketahanan layanan akibat cascading failure, ketergantungan antarlayanan yang dinamis, serta keterbatasan mekanisme fault tolerance berbasis ambang statis. Pendekatan seperti circuit breaker dan bulkhead hanya memberi perlindungan terbatas ketika beban dan latensi berubah cepat. Untuk menjawab gap tersebut, penelitian ini memperkenalkan Renovator, kerangka kerja ketahanan yang memperluas circuit breaker melalui pemantauan adaptif dan pemulihan otomatis. Evaluasi pada simulasi Sistem Presensi dengan empat skenario yaitu cascading failure, latency spike, normal load, dan single-service failure menunjukkan peningkatan signifikan dibandingkan baseline: ketersediaan naik (86,31% menjadi 93,95%), MTTR berkurang 49–67%, tingkat kesalahan turun 55–63%, serta latensi membaik 20–27% tanpa memengaruhi throughput. Kontribusi utama penelitian ini adalah pengembangan Renovator sebagai mekanisme circuit breaker yang lebih adaptif dan otomatis untuk meningkatkan ketahanan microservices.

ABSTRACT
Microservices architectures face resilience challenges due to cascading failures, dynamic dependencies, and the limitations of fault tolerance mechanisms that rely on static thresholds. Techniques such as Circuit Breaker and Bulkhead provide only partial protection under rapidly changing workloads. To address this gap, this study introduces Renovator, a resilience framework that enhances circuit breaker functionality through adaptive monitoring and automated recovery. Evaluated on a simulated Attendance System under four scenarios—cascading failure, latency spike, normal load, and single-service failure, Renovator shows notable improvements over the baseline: availability increases (from 86.31% to 93.95%), MTTR decreases by 49–67%, error rates drop 55–63%, and latency improves 20–27% with no throughput degradation. The main contribution is an adaptive and automated circuit-breaker–based framework to strengthen microservices resilience.
