Autoscaling cloud resources with real-time metrics

Kaithe, Bhanu Kiran (2025) Autoscaling cloud resources with real-time metrics. World Journal of Advanced Research and Reviews, 26 (2). pp. 435-442. ISSN 2581-9615

This article comprehensively examines cloud resource autoscaling systems driven by real-time metrics, exploring their theoretical foundations, practical implementations, and emerging challenges. The article analyzes the evolution from static resource allocation to sophisticated dynamic scaling mechanisms that continuously monitor performance indicators and automatically adjust cloud infrastructure to match demand patterns. The article investigates critical performance metrics across computational, network, and application domains that inform scaling decisions, alongside the collection methodologies and temporal analysis techniques that transform raw data into actionable intelligence. The article identifies distinctive capabilities and limitations that influence adoption decisions. The article further evaluates performance assessment methodologies, cost-performance tradeoffs, and responsiveness characteristics across diverse application types. Finally, the article addresses pressing challenges in multi-dimensional resource optimization, containerized and serverless environments, edge computing contexts, and sustainability integration, concluding with an outlook on emerging technologies that promise increasingly autonomous and business-aligned scaling capabilities. This article contributes to both the theoretical understanding and practical application of autoscaling technologies in modern cloud environments.
