Garbage Collection GC in Modern Java Applications: GC Considerations for Microservices

on YouTube ↗19m

" summary

Microservices at Get Your Guide experience frequent out‑of‑memory crashes, latency spikes and retries traced to GC behavior: the search service hits failure when traffic exceeds 700 requests per second and switching to ZGC cuts tail latencies and pauses without extra CPU, while the inventory service stores huge 16‑month objects and needs G1GC for predictable collection. Clear metrics on GC frequency, pause durations and heap object sizes drive the decision and validate fixes.
