When a business is just starting out, cost matters more than complexity. You donβt need Kubernetes, Auto Scaling Groups, or managed everything on day one β you need something secure, maintainable, and cheap that can grow later.
This is the simplest architecture I recommend for an initial business website, built entirely in an AWS environment π
π Domain & DNS
- Domain purchased from GoDaddy (or any registrar)
- AWS Route 53 for DNS management
- Clean separation: registrar β DNS
- Easy to migrate later if needed
ποΈ Database Server (Free Tier)
- EC2 t2.micro (~10GB)
- PostgreSQL / MySQL
- Private network access only (no public exposure)
- Automated backups (snapshots + logical dumps to S3)
- At this stage, self-managed DB is cheaper than RDS and fully sufficient.
π§© Application Server (Free Tier)
- EC2 t2.micro (~20GB)
- Nginx + Certbot (TLS termination)
- Application running in Docker
- Promtail + Loki + Grafana for lightweight log monitoring
- Public-facing entry point for users
- Nginx handles SSL, Docker keeps deployments clean, and observability is added without heavy cost.
π CI/CD Server (On-Demand Only)
- EC2 t3.small
- Nginx & Certbot (secured Jenkins access)
- Jenkins for CI/CD
- Git, Docker, Docker Compose
- Started only during deployments, stopped afterward
This is the biggest cost saver. CI/CD does not need to run 24/7.
π Deployment Flow
- Developer commits code to Git
- Jenkins builds artifact & Docker image
- Jenkins deploys to App Server via SSH
- Docker Compose restarts the application
Simple. Predictable. No magic.
π° Cost Optimization Highlights
- Stay within AWS Free Tier as long as possible
- Stop CI/CD server when idle
- Use Security Groups instead of complex firewalls
- Snapshot + S3 backups instead of expensive DB services
π How this grows later
- When traffic and revenue increase:
- Move DB to RDS
- Add Load Balancer
- Introduce Auto Scaling
- Add WAF & CDN
But only when the business justifies it.
π‘ Architecture should serve the business stage, not the ego.
Start simple. Secure the basics. Scale with confidence.
If youβre building an MVP or advising early-stage teams, feel free to reuse or adapt this blueprint.
Iβd also love to hear your thoughts β what would you change or optimize in this setup for a real-world startup?
