Operationalizing Reliability Engineering at Scale in Hybrid Cloud Banking Systems

Abstract

The emergence of hybrid cloud architectures in the banking sector has necessitated the evolution of traditional operational practices toward Site Reliability Engineering principles to ensure continuous service availability and regulatory compliance. This research examines the operationalization of reliability engineering practices within large-scale hybrid cloud banking infrastructures, analyzing implementation frameworks, performance metrics, and organizational impacts observed between 2016 and May 2021. Quantitative analysis revealed that financial institutions implementing comprehensive SRE practices achieved 99.93 to 99.96 percent service availability, representing significant improvement from the baseline 99.5 to 99.7 percent observed in traditional banking infrastructures.
