The Digital Operational Resilience Act (DORA) has applied to EU financial entities since 17 January 2025. Proving compliance takes more than policy documents — it takes resilient code, and eighteen months in, a lot of Irish financial entities still have the paperwork ahead of the architecture, not behind it.
Resilience by Design
DORA mandates that you actually test your recovery capabilities, not just document them. If your disaster-recovery plan is a 40-page PDF nobody has tested in two years, you are non-compliant regardless of how thorough the document reads. The regulation expects scenario-based testing — proving a specific failure mode is survivable, not asserting that it probably is.
Key Architecture Shifts
- Multi-region active/active: moving away from "cold standby." In modern cloud systems (DynamoDB Global Tables, Aurora Global), you can run simultaneously in Dublin and Frankfurt. If one region falls, the other takes over instantly with zero data loss.
- Circuit breakers: making sure one failing third-party API doesn't take down your entire banking portal.
- ICT incident logging: DORA requires major incidents to be classified and, where they cross the significance thresholds, reported to the Central Bank within tight time windows. That means your monitoring stack needs to produce a clean, timestamped incident record automatically — reconstructing one after the fact from scattered logs is where most "compliant on paper" teams actually fail.
Vendor Risk Management
DORA also holds you accountable for your third-party ICT providers, including cloud. You need an up-to-date register of information covering every critical third-party dependency, and an engineered exit strategy for each one: if your primary cloud provider had a regional outage or ended the relationship, how fast could you actually move, and what would you lose? Containerization and infrastructure-as-code are the practical hedge — they turn "we could migrate" into something you've actually tested, not just asserted in a vendor questionnaire.
What this looks like delivered
We've built regulatory reporting infrastructure for the Irish financial sector before — see the LAAD compliance reporting and APEX actuarial platform case studies for what audit-ready, traceable systems look like in production.
