Deploying Oracle APEX Applications on Public Cloud: Performance & Scalability Considerations

Abstract

The deployment of Oracle Application Express (APEX) on public cloud environments introduces new paradigms in performance scalability, elasticity, and cost efficiency for enterprise-grade low-code applications. This study presents a comparative evaluation of APEX deployments across bare-metal, virtual machine, and autonomous serverless configurations on Oracle Cloud Infrastructure (OCI) and AWS platforms. The experimental analysis quantifies throughput, latency, and resource utilization under concurrent user loads, demonstrating that autonomous serverless environments outperform traditional configurations through adaptive compute allocation and in-memory PL/SQL execution. The research further outlines optimal autoscaling thresholds, architectural guidelines for cost-effective resource management, and resilience strategies for fault-tolerant hosting. By integrating insights from database-level optimization and cloud-native elasticity, the work establishes a methodological foundation for intelligent APEX deployment design and paves the way for future incorporation of ONNX-based inference and AutoML-driven scaling intelligence.
