Fintech hosting migration

Modernizing hosting for a fintech platform

A fintech product running on dedicated hosting needed stronger resilience and faster release cycles. We moved the platform to AWS, built a secure landing zone, and automated deployments end-to-end.

The situation

What was wrong

The legacy hosting provider required manual provisioning and had limited redundancy options. Releases were scheduled after-hours, and uptime depended on a small operations team.

  • Single points of failure across compute and storage.
  • Manual deployment workflows with long lead times.
  • Limited security baselines for audits and vendor reviews.

Outcome

Simplified deployments and improved site reliability.

How we worked

The approach, step by step

Stabilise delivery early, then build the foundation that keeps it stable once we hand it back.

    1

    Landing zone build

    Established a secure AWS foundation with network segmentation, IAM guardrails, and logging.

    2

    Frontend migration

    Moved the public web application to S3 and CloudFront for improved latency and resilience.

    3

    Backend modernization

    Containerized backend services and deployed to ECS with automated releases.

    4

    Observability

    Implemented monitoring, alerting, and on-call readiness for the new stack.
