AWS migration for a fintech app — zero downtime, 99.98% uptime since
- Challenge
A fintech app running on a single VPS was experiencing monthly outages averaging 4 hours each. Deployments required manual SSH sessions. No staging environment, no monitoring.
- Solution
Migrated to AWS with ECS Fargate, RDS PostgreSQL, and CloudFront. Built GitHub Actions CI/CD with automated tests and blue/green deployments. Set up Grafana + PagerDuty alerting.
- Result
99.98% uptime in the 12 months since migration. Deployment time: 45 minutes manual → 4 minutes automated. Zero unplanned outages since go-live.
