<![CDATA[Cloud delivery of financial services is increasingly adopted for mission-critical applications such as portfolio management, electronic trading, risk analytics, fraud detection, and regulatory reporting. However, distributed multi-account and multi-region cloud environments introduce persistent challenges in operational visibility, security governance, compliance monitoring, and service resilience. This study develops and evaluates a generalized framework for enterprise cloud observability and security governance in financial services organizations. The framework integrates centralized log analytics, multi-account network governance, identity and access management, automated policy enforcement, AIOps-based predictive operations, and cloud-native disaster recovery within a unified operational model. The approach combines observability engineering, cloud governance, security control, and financial-sector compliance requirements to establish coordinated monitoring and governance across distributed environments. Experimental evaluation was conducted to assess the framework's effectiveness in operational monitoring, security governance, compliance management, anomaly detection, incident response, and resilience. The results demonstrate that integrated observability and governance mechanisms improve the timeliness of anomaly detection and incident resolution, reduce compliance violations, and strengthen operational resilience across complex multi-account environments. Centralized visibility and automated policy controls also improve consistency in security enforcement and compliance oversight, while predictive operational capabilities support earlier identification of potential service disruptions. The findings indicate that the framework provides a structured and adaptable model for organizations requiring strong visibility, controlled access, continuous compliance, and reliable cloud-based financial services. Its modular architecture also supports adaptation to other highly regulated sectors, including banking, insurance, healthcare, and government services. The study concludes that integrating observability with security governance provides a practical foundation for managing operational complexity and regulatory requirements in distributed cloud environments]]>
