Modernizing Core Banking for the Cloud-First Era
How TechHost partnered with a leading European FinTech to migrate a legacy monolithic core banking platform to a highly resilient AWS microservices architecture.
The Challenge
The client faced critical limitations with their legacy on-premise infrastructure that hindered global expansion plans.
Scalability Bottlenecks
Monolithic architecture prevented independent scaling of transaction processing, resulting in performance degradation during peak periods.
High Operational Costs
Fixed hardware costs and manual infrastructure maintenance created significant overhead.
Limited Resilience
Single points of failure across the stack made disaster recovery difficult and increased downtime risks.
The Solution: Lift & Modernize
A strategic migration to AWS, rebuilding core components as cloud-native microservices while maintaining business continuity.
Microservices Transition
Decomposed the monolithic platform into independent services with isolated scaling and deployment.
Security-First Design
Implemented IAM controls, encryption, secrets management, and compliance automation.
Infrastructure as Code
Provisioned all environments using Terraform and GitOps workflows.
Automated CI/CD
Created deployment pipelines reducing release cycles from weeks to minutes.
Technologies Leveraged
