DOI: Resilience Engineering in Financial Systems: Strategies for Ensuring Uptime During Volatility
Hari Dasari , Expert Infrastructure Engineer Leading Financial Tech Company Aldie, VirginiaAbstract
Financial institutions suffer volatility, regulatory scrutiny, cyber risks, and complex technical linkages. System outages and operational failures can influence market stability, customer trust, and regulatory compliance in this setting. For proactive financial system design that can predict, withstand, and recover from interruptions with little service deterioration, resilience engineering is essential.
This article examines financial system resilience engineering strategies in detail. It covers redundancy, observability, adaptive capacity, microservices, multi-region deployments, service meshes, Site Reliability Engineering (SRE), chaotic testing, and real-time monitoring. It also examines worldwide regulatory frameworks like the UK FCA recommendations, EU DORA regulation, and US FFIEC standards, highlighting regulatory alignment in operational resilience.
JPMorgan Chase's resilience architecture is examined in detail, along with AI-driven observability, Zero Trust architectures, edge computing, and blockchain-based settlements. This research integrates technical, operational, and compliance methods to help financial institutions maintain uptime and service continuity in a dynamic digital economy.
