Cloud-Native SaaS Migration & Modernization

A UK-based FinTech leader in SME lending was burdened by its legacy, on-premise monolithic architecture. The platform was struggling with inconsistent 3-second page loads, frequent downtime (67% uptime), and significant security vulnerabilities.

The primary blockers included: - **Scalability Issues**: The system couldn't handle the load during month-end surges, leading to lost loan applications. - **Compliance Gaps**: They were unable to onboard major institutional investors due to a lack of automated SOC2 and ISO27001 compliance frameworks. - **Developer Friction**: Deploying a single change took over 4 hours and required manual intervention, slowing their feature release cycle by months.

They needed a complete cloud-native re-architecture that prioritized reliability, security, and developer velocity.

BitFleche executed a phased "bridge and modernize" strategy to migrate the entire lending platform to a microservices architecture on AWS.

Our transformation plan included: - **Kubernetes Orchestration**: Re-architected the monolith into 14 core microservices deployed via Amazon EKS, allowing for independent scaling and failure isolation. - **Infrastructure as Code (IaC)**: Used Terraform to codify their entire global infrastructure, ensuring 100% reproducible environments and enabling multi-region disaster recovery. - **Security & Compliance Automation**: Implemented a "compliance-as-code" pipeline that automatically scans for vulnerabilities and logs all access, directly supporting their successful SOC2 Type II audit. - **High-Performance Data Layer**: Migrated from a single giant database to a polyglot data strategy using Amazon Aurora for transactions and Redis for rapid query caching. - **Automated CI/CD**: Established a zero-downtime deployment pipeline using GitHub Actions, reducing their deployment time from 4 hours to under 6 minutes.
