Hybrid & Cloud-Native Blueprint: AWS Migration for Financial Services
Tokyo-Based Financial Company
35% Savings Potential
25% Planning Boost
60% Improvement
Summary
Aokumo delivered a comprehensive hybrid cloud strategy that empowered a leading financial institution to modernize their legacy infrastructure. By creating a detailed roadmap blending on-premises optimization with AWS cloud migration, we delivered immediate business impact—reducing planning cycles by 60% and identifying 35% potential cost savings—all without changing a single line of code.
The Challenge
The institution operated a monolithic infrastructure built around a central Oracle database and tightly coupled .NET applications running on Windows Server. While these systems were reliable, they had become a liability to agility, scalability, and innovation.
Specific pain points included:
- Centralized Risk Exposure: A single Oracle database powering multiple core systems created significant operational risk.
- Unsustainable Costs: On-prem infrastructure and proprietary software licensing inflated OPEX and limited investment flexibility.
- Legacy Technical Stack: .NET frontend apps on Windows lacked portability and made modern DevOps integration difficult.
- Limited Scalability: Existing architecture could not scale horizontally without significant engineering effort.
- Manual Operations: Environment provisioning required IT-heavy effort and slowed deployment cycles.
- Compliance Pressures: Lack of observability made regulatory reporting and traceability difficult in a real-time environment.
The Aokumo Solution
Aokumo’s solution began not with cloud migration itself, but with strategic planning and architecture design, enabling the client to move with precision and control.
- Strategic On-Premises Optimization: Aokumo analyzed existing infrastructure and proposed IaC implementation using Terraform and Ansible to enforce configuration consistency and version control—even in legacy environments.
- Progressive Containerization Strategy: Rather than initiating a full re-platforming, Aokumo recommended containerizing .NET workloads using Docker, making them portable and preparing them for future Kubernetes or ECS adoption.
- DevOps Acceleration Framework: Proposed a GitOps workflow using Jenkins and JFrog Artifactory, helping unify deployment pipelines across on-prem and cloud environments—speeding up releases while maintaining control.
- Phased AWS Migration Blueprint: Identified “lift-and-improve” workloads that could transition early with minimal code changes. Focused on leveraging AWS managed services (like RDS, EFS, S3) to reduce operational overhead.
- Unified Observability & Compliance Strategy: Developed an SLO-driven observability model combining logging, monitoring, and alerting across environments, ensuring full operational transparency and audit readiness.
- CI/CD-Driven Environment Provisioning: Created a replicable, automated environment setup framework spanning hybrid infrastructure to reduce delays in project onboarding and change management.
The Results
This hybrid roadmap unlocked tangible outcomes before implementation even began:
- 25% Planning Efficiency Improvement: Architecture clarity accelerated consensus among stakeholders across IT, compliance, and leadership.
- 35% Cost Reduction Potential: Identified short- and mid-term opportunities to reduce license dependency and migrate low-risk workloads.
- 60% Faster Preparation Cycles: Planning and migration readiness time cut from months to weeks.
- Significant Risk Mitigation: Resilience was built into design, reducing exposure to central infrastructure failure and improving availability forecasting.
Conclusion
Aokumo’s hybrid cloud advisory gave this leading financial institution more than a plan—it delivered strategic clarity, cost optimization, and risk mitigation. The approach bridged the legacy and cloud-native worlds without business disruption, allowing the client to modernize with confidence at their own pace.
By addressing technical debt, optimizing for AWS, and introducing scalable DevOps and observability foundations, the client now has a blueprint for sustainable transformation. Aokumo continues to guide financial institutions on their journey from monolith to hybrid, unlocking value one strategic decision at a time.
"Hybrid cloud is not a detour — it’s a deliberate strategy to bridge legacy and cloud-native without slowing the business down."
