Building Cloud-Agnostic Logging for Node.js: Production-Grade ELK Stack Without Vendor Lock-In

This approach solves a critical architecture challenge for teams running microservices across multi-cloud environments: achieving production-grade observability while avoiding vendor lock-in. By implementing a Non-Blocking Logger Factory pattern with ELK stack and proper resilience mechanisms, organizations can maintain centralized logging without dependency on proprietary cloud services. The design ensures logging infrastructure becomes a reliability enabler rather than a single point of failure.
