Cross-Layer AI for zero-downtime cloud network infrastructure

Vaidya, Dakshaja Prakash (2025) Cross-Layer AI for zero-downtime cloud network infrastructure. World Journal of Advanced Engineering Technology and Sciences, 15 (2). pp. 3070-3077. ISSN 2582-8266

Cross-Layer Artificial Intelligence represents a transformative approach to achieving zero-downtime cloud network infrastructure through comprehensive visibility and autonomous remediation capabilities. This technical review explores how cross-layer AI integrates telemetry data across traditionally isolated domains—from application code to physical infrastructure—creating unprecedented insight into system behavior and enabling predictive maintenance. By correlating events across architectural boundaries, these systems detect emerging issues before they impact services, while autonomous remediation mechanisms maintain continuity during component failures. The architectural framework incorporates data ingestion from heterogeneous sources, correlation engines that establish causal relationships between disparate events, predictive analytics for anomaly detection, and orchestration systems that execute appropriate responses. Advanced machine learning techniques, including unsupervised learning for baseline establishment, reinforcement learning for response optimization, and explainable AI for operational transparency, form the technological foundation. Despite implementation challenges related to scale, data quality, legacy integration, and security considerations, real-world deployments across financial services, cloud providers, telecommunications, and healthcare demonstrate significant improvements in availability, mean time to recovery, and operational efficiency. As cloud architectures grow increasingly complex, cross-layer AI offers a compelling path toward self-healing infrastructure that fundamentally changes how organizations approach reliability and resilience in mission-critical digital environments.
