Cloud-Native Resilience and DORA Compliance: A DevOps implementation framework for Financial Services
Year: 2025
Type: article
Abstract: : European financial institutions face a distinctive challenge in operationalising DORA: transforming observability, incident governance and third-party control from compliance exercises into embedded elements of software delivery. The focus is practical. Observability is anchored in user-facing indicators and traceable records rather than tool catalogues, so that evidence read by engineers can also be followed by supervisors. Incident management is framed as real-time classification against regulatory thresholds with an auditable trail that shows who decided, on what basis and when notifications were sent. Third-party risk moves from periodic review to continuous dependency visibility, vendor-impact correlation and exercised exit strategies that prove substitutability. Two implementation archetypes recur in practice. Large banks advance by placing controls at legacy boundaries and migrating inward through bounded services while keeping external contracts stable. Mid-size and greenfield organisations adopt a platform-led model in which golden paths and asynchronous enforcement preserve speed without losing accountability. Across both contexts, two patterns explain most success: integration before tools, and automation measured by outcomes such as time to detect, time to recover and change failure rate. Limits are explicit. Results depend on disciplined evidence generation and on validating improvements across incidents rather than relying on narrative claims. The aim is lower compliance cost and resilience that customers can feel. --- Interactive supplementary material:DORA x DevOps - Interactive Demo (GitHub Pages)It demonstrates how operational metrics (MTTR, CFR, RTO/RPO, multi-region resilience, supply-chain security) can be modeled within a DORA compliance framework. --- Official reference version:Zenodo DOI: https://doi.org/10.5281/zenodo.17344907 Parallel version available:SSRN: https://ssrn.com/abstract=5541800 - DOI: https://doi.org/10.2139/ssrn.5541800
