Case Study: MUFG – Scalable AWS Platform Enablement

Client Snapshot

Industry: Banking & Financial Services

Company Size: Global enterprise

Region: North America & Global Operations Overview: MUFG is one of the world’s largest financial institutions. Their cloud platform team was looking to scale AWS account governance, network segmentation, and observability across an enterprise spanning nearly 100 AWS accounts.

The Challenge

  • A small internal team with limited capacity to deliver the scope of enterprise-wide cloud platform enablement
  • No centralized management of subnets, IPs, or logging across AWS accounts
  • Existing Terraform modules lacked maturity and coverage
  • Needed rapid execution and documentation to bring vision into reality
  • Complex integration with on-premises logging systems (e.g., Splunk)

Why They Chose Us

  •  Recognized AWS partner with strong credentials and deep Terraform + DevOps experience
  • Ability to scale infrastructure management across 80–100 AWS accounts
  • Demonstrated thought leadership and rapid delivery from day one
  • Experienced in hybrid-cloud integrations and log pipeline automation

Our Solution

  • Extended and enhanced existing modules

  • Created new reusable infrastructure-as-code patterns

  • Enforced consistency across accounts via Terraform

  • IP and Subnet Management at Scale:

  • Designed IP allocation strategy across accounts and VPCs

  • Automated subnet creation using parameterized modules

  • Introduced tagging conventions for traceability

  • Centralized Logging Pipeline:

  • Configured real-time log streaming from all AWS accounts

  • Integrated with Splunk using cross-account ingestion pipelines

  • Ensured compliance with audit/security logging requirements

  • Automation via Azure DevOps:

  • CI/CD pipelines deployed Terraform modules seamlessly

  • Built automated approvals, drift detection, and validation workflows

  • Delivered documentation and onboarding support for internal teams

  • Documentation & Diagramming

  • Produced detailed runbooks and architecture diagrams

  • Created onboarding guides and design docs to ensure maintainability

Outcomes & KPIs

  • Standardized, scalable Terraform infrastructure modules

  • Full IP and subnet segmentation plan implemented

  • Azure DevOps pipelines orchestrating all infra deployments

  • Delivered ahead of schedule
