A 150-year-old bank automates assessment and containerization end to end.

# BFSI Customer Story — 70% ops cost reduction

**Industry:** BFSI
**Cloud:** Multi-Cloud
**Outcome:** 70% ops cost reduction

## Summary
Manual, per-application assessment was the bottleneck in a multinational bank's migration. Automating discovery through deployment cut operational cost 70% and made every workload traceable to source.

## The Challenge
A multinational investment bank with a history spanning over 150 years was executing a multi-year plan to move applications from its on-premises estate into the cloud — cutting run-cost while lifting the productivity of its business users.The bottleneck sat upstream. The bank had to assess a large existing application estate, identify the right strategy for each target-cloud landing, and then establish the environments to receive it. Done by hand, that work was time-consuming and susceptible to human error — and in a domain bound by confidentiality and organizational compliance, a mis-assessed dependency is not a rounding error.It also wanted headroom: the move was framed as a multi-year strategy, with modernization opportunities explored as applications landed rather than deferred to a second programme. What it needed was an assessment and migration motion trustworthy at estate scale — automated, repeatable, auditable. Not another wave of one-off scripts.

## The Solution
Discovery, container transformation, and cloud deployment ran as one continuous workflow — so the dependency data gathered up front determined the containers that got built, and the containers that got built were exactly what shipped.CHAI DART pulled application details and their component inventory across the estate, surfacing dependencies as data rather than tribal knowledge. Those dependency maps became the direct input to containerization — and to the rationalization call on each application.The bank wanted its application base moved to a newer, supported version. CHAI Flow changed the Dockerfile in the transform step and rebuilt the application containers on the upgraded base the bank specified — not a re-platforming project, a pipeline change. CHAI Universe then deployed the built containers into the bank's desired cloud environment, standardized as Application Blueprints so the next application followed the same path. Repository integration closed the loop with end-to-end traceability from source to running workload.

## The Outcome
The bank realized 70% operational cost savings from efficiently deploying product versions across client tenants and environments, with faster time-to-market on standardized Application Blueprint templates replacing hand-crafted work.Assessment became automatic — components and dependencies discovered as data, not hand-catalogued — and the container estate moved onto supported base images through a Dockerfile change rather than a rebuild programme.Every application after the first follows a path that already exists: assessed automatically, containerized on a supported base, and deployed as a standardized blueprint rather than a fresh project. With end-to-end traceability from source to running workload, the bank can evidence what is running where — keeping agility without trading away compliance.
