Mexican multi-bank institution modernising its digital landscape
Hybrid Banking Modernization
Brownfield · Cloud + on-premise · Active
Status·Architecture & Transformation Design — Active
Enterprise and transition architecture for a banking landscape combining cloud, on-premise appliances and legacy systems: capability and core assessment, baseline and target architectures, transition plateaus, work packages and a governed roadmap.
Role: Platform Architect / interim Solution Architect
Context
A brownfield environment combines cloud, on-premise appliances and legacy systems.
Tension
The bank needs target-state modernization without assuming all legacy capabilities can move at the same pace.
Scope
Target architecture defined independently of legacy constraints, with explicit transition states, layer boundaries and anti-corruption boundaries.
Transition
The as-is informs the target architecture; it does not imprison it. Transition states are declared rather than implied, so each legacy capability can move on its own schedule.
Governance
Architecture governance and formal conformity assessments applied to irreversible decisions, with security architecture treated as part of the decision set rather than a later review.
Result
Baseline and target architectures with explicit transition plateaus, work packages and a governed decision path for the irreversible choices.
