Crypto Exchange: GitOps Infrastructure and Zero-Downtime Deploys in 7 Days

A high-load digital asset trading platform operated on manual deployments with no CI/CD. Every update was a risk. In 7 days, we built GitOps infrastructure with full environment reproducibility and zero downtime.

The Problem

  • Manual SSH deployments — every release was stressful
  • No CI/CD: tests ran manually, sometimes skipped
  • Different configs on dev/staging/prod — 'works on my machine'
  • Secrets in .env files committed to the repo
  • Rollback after failed deployment took 2-4 hours

The Solution

  • GitOps with ArgoCD: every change is a PR, review, auto-deploy
  • GitLab CI/CD with automated tests and security scanning
  • Terraform for 100% reproducible infrastructure
  • Vault for secrets management, Keycloak for SSO
  • Blue/Green deploys: rollback in 30 seconds with one command

What Was Done in 7 Days

Day 1

Audit & Architecture

  • Audit of current infrastructure and CI/CD processes
  • GitOps architecture design with ArgoCD
  • Zero-downtime migration strategy definition
Day 2-3

Infrastructure & Security

  • Terraform modules for cloud infrastructure
  • Vault setup for secrets management
  • Keycloak for centralized authentication
Day 4-5

CI/CD & GitOps

  • GitLab CI/CD pipelines with automated testing
  • ArgoCD for GitOps deployments to Kubernetes
  • Blue/Green and Canary deployment strategies
Day 6-7

Monitoring & Handover

  • Grafana dashboards for business and technical metrics
  • Alerts and runbooks for the team
  • Documentation and team training

"Before, every deployment was an event. Now we deploy 5-6 times a day and don't think about it. ArgoCD just works."
