Services delivered

Before and after

Downtime on this FinTech platform hit revenue, customer trust and regulatory compliance, yet deployments were manual and error-prone and releases took weeks to reach production.

Before

  • Single points of failure in the infrastructure, with limited monitoring and slow incident detection.
  • No standardized CI/CD pipelines, and security checks run manually and inconsistently.
  • Faster releases had to come with near-zero downtime.

After

  • 99.99% application uptime in production
  • 6× deployment frequency, releases in hours not weeks
  • 40% fewer operational incidents

The solution

Solution path

  1. Git
  2. CI: build · test · scan
  3. GitOps
  4. Amazon EKS (multi-AZ)
  5. Production

How it was delivered

  1. Phase 1

    Designed a multi-AZ architecture with isolated Dev, UAT and Prod, all provisioned with Terraform.

  2. Phase 2

    Containerized the applications on Amazon EKS and built automated CI/CD for build, test, security scanning and deployment, with GitOps rollouts and fast rollbacks.

  3. Phase 3

    Introduced rolling, blue-green and canary releases, DevSecOps scanning and centralized monitoring, logging and alerting.

Questions about this project

How did the FinTech reach 99.99% uptime?

A multi-AZ architecture removed single points of failure, and zero-downtime release strategies (rolling, blue-green and canary) on Amazon EKS meant deployments no longer caused outages.

How much faster did releases become?

Release cycles dropped from weeks to hours, deployment frequency rose six-fold, and operational incidents fell by 40%.
