Operational resilience
Regulators expect demonstrated recovery of critical business services, not component-level uptime figures.
Banking, insurance, and capital markets
Financial Services
Financial institutions operate under supervisory examination, resilience expectations, and vendor concentration scrutiny. Architecture decisions are evaluated for recoverability as often as for capability.
Business challenges
What makes change difficult in this sector
Change control
Rapid delivery has to coexist with documented approval and segregation of duties.
Concentration risk
Cloud and vendor dependency requires documented exit and alternative-path analysis.
Data lineage
Reported figures must be traceable from source to statement.
Architecture principles
Decisions we hold constant
- Critical business services are the unit of resilience planning
- Separation of duties is enforced by platform configuration
- Every reported metric has a documented lineage
- Recovery is tested, not asserted
Governance considerations
- Impact tolerance defined per critical business service
- Model and data governance with named accountable owners
- Change approval evidence retained with deployment records
- Third-party and cloud exit analysis maintained current
Transformation phases
A sequence that protects service while it changes
Service mapping
Identify critical business services and their supporting technology chain end to end.
Control hardening
Establish identity, key management, and separation-of-duties controls in the target platform.
Resilience validation
Test recovery of mapped services against defined impact tolerances.
Governed delivery
Embed evidence capture into the deployment pipeline.
Technology alignment
Where platform capability supports the approach
Cloud platform
Azure landing zones with policy guardrails, separated subscriptions, and paired-region design.
Data
Microsoft Fabric with catalogued lineage for reported measures.
Governance
Microsoft Purview for data governance and access transparency.
Security
Microsoft Sentinel for consolidated detection and supervisory reporting inputs.
