Resilient cloud-native retirement platforms with Angular, React, and AWS

Robust cloud-native retirement systems represent a convergence of financial software engineering, distributed systems design, and user-centered digital service delivery. The growing sophistication of retirement planning applications necessitates the development and evaluation of resilient architectures capable of scaling under changing workloads while maintaining service continuity in cloud ecosystems. This paper develops and evaluates a hypothetical resilient retirement application based on Angular, React, and AWS-hosted services. Empirical testing in conditions of stress, cold-start mitigation and autoscaling prove that predictive scaling and adaptive circuit breakers contribute significantly to minimizing latency and propagation of failures, and thus, enhancing mean-time-to-recovery and availability. The paper provides a coherent set of conceptual and empirical models of how to apply the principles of resilience-oriented design to both front-end and back-end layers of cloud-native systems. The results have practical implications for architects of financial systems and digital platform engineers who need to find the right trade-off between scalability, compliance, and user experience in critical applications.
