Zero-downtime AWS migration for a multinational financial services platform.
Secure migration delivery across closed-network AWS environments with Infrastructure as Code automation, resilient networking and CI/CD modernisation.
Challenge
Migrating critical banking infrastructure without operational disruption.
The engagement focused on migrating a multinational financial services platform from legacy bare-metal infrastructure to AWS while maintaining uninterrupted operational availability.
Requirements included strict networking controls, closed-network infrastructure patterns, resilient multi-region design and deployment automation across multiple isolated environments.
Approach
Infrastructure automation aligned to regulated delivery requirements.
AWS infrastructure was engineered using Application Load Balancers, Network Load Balancers, PrivateLink, Direct Connect, Transit Gateway and multi-region Oracle database deployments.
Infrastructure provisioning and operational workflows were automated using Terraform, GitHub Actions, CodeBuild, CodePipeline, ECS and ECR, enabling consistent delivery across more than twenty isolated environments.
Focus areas
Core engineering and delivery areas
SWIFT banking migration
Migration of a multinational banking platform from legacy infrastructure to AWS with zero downtime requirements.
AWS infrastructure
Engineered secure AWS infrastructure using ALB, NLB, RDS Oracle and multi-region connectivity patterns.
Closed-network Terraform
Developed reusable Terraform modules for highly controlled and isolated cloud environments.
Multi-region architecture
Implemented resilient multi-region networking and database architecture for operational continuity.
CI/CD automation
Built deployment automation using GitHub Actions, CodeBuild, CodePipeline, ECR and ECS workflows.
Delivery details
Secure cloud migration with Infrastructure as Code at scale.
Terraform modules were engineered specifically for controlled and closed-network cloud environments, supporting repeatable deployments while maintaining strict networking and security requirements.
CI/CD automation accelerated infrastructure delivery and reduced operational overhead through consistent validation, deployment orchestration and environment standardisation.
Multi-region architecture patterns improved resilience and operational continuity while hybrid connectivity patterns enabled secure communication between cloud infrastructure and existing enterprise systems.
