Complete Cloud Setup for a Startup: Domain Mapping, Route 53, S3 Storage, Backups & Deployment

Complete Cloud Setup for a Startup: Domain Mapping, Route 53, S3 Storage, Backups & Deployment

A complete cloud infrastructure setup for a startup, including Route 53 domain mapping, S3-based storage, automated backups, CI/CD deployment, and secure scalable hosting.

Client

A newly funded startup building an online platform and needing a complete, reliable, secure, and scalable cloud environment for launch.

They had no existing infrastructure and needed an end-to-end setup covering:

  • Domain + DNS

  • Hosting

  • File storage

  • Backups

  • CI/CD deployment

  • Cloud security

  • Cost-efficient scaling

Project Overview

The client wanted to deploy their platform quickly but professionally, with a strong foundation for future growth. Their requirements included:

  • Custom domain mapping

  • AWS Route 53 DNS configuration

  • Static & dynamic hosting setup

  • S3 storage for assets, logs, and backups

  • Automated backup strategy

  • Secure & smooth CI/CD pipeline

  • A scalable architecture with monitoring

We delivered a full cloud infrastructure using AWS, ensuring the platform was production-ready from day one.

🧩 Key Challenges

1. No Existing Infrastructure

Everything had to be built from scratch — DNS, hosting, deployment, file storage, monitoring, etc.

2. Startup-Level Budget Constraints

The setup had to be cost-efficient, avoiding unnecessary heavy services while keeping scalability intact.

3. Need for Zero-Downtime Deployment

The client wanted automated deployments with no disruption to users.

4. Secure, Reliable Backups

The platform required backups for:

  • User uploads

  • Database

  • Logs

  • Config files

5. Domain Mapping Across Services

The startup needed:

  • www → main website

  • app → web application

  • api → backend services

🔧 Our Solution

We engineered a complete cloud ecosystem based on AWS services.

1. Domain Mapping with AWS Route 53

We configured all domain records including:

  • A records

  • CNAMEs

  • ALIAS records for root domain

  • Subdomains for:

    • app.domain.com

    • api.domain.com

    • cdn.domain.com (pointed to S3/CloudFront)

We also implemented:

  • DNS health checks

  • Failover routing supports

  • TTL optimization for faster propagation

2. Scalable Hosting Infrastructure

Depending on the client’s app type, we set up:

Option A — EC2 + Load Balancer

  • Auto Scaling Group

  • Nginx reverse proxy

  • SSL via ACM

Option B — S3 + CloudFront

  • Static hosting for landing pages

  • Global CDN distribution

  • HTTPS enforced

Option C — Containerized Deployment (ECS/ECR)

  • Docker-based build

  • ECS Fargate (serverless containers)

  • ECR for container storage

(We choose based on the client's architecture.)

3. S3 Storage Setup

We used Amazon S3 for:

  • User file uploads

  • Static assets

  • Backup storage

  • Log archiving

We also configured:

  • Lifecycle rules to move cold data to Glacier

  • Versioning to protect against accidental deletion

  • IAM roles for secure uploads

  • Bucket policies blocking public access

4. Backup & Disaster Recovery Strategy

We implemented:

✔ Database backups (RDS automated snapshots)
✔ Daily S3 incremental backups
✔ Weekly full backups stored in separate region
✔ Off-site backup option to minimize risk
✔ Cron-based backup monitoring scripts
✔ Retention policies (7-day, 30-day, 90-day)

This ensures the platform is recoverable in minutes, not hours.

5. CI/CD Deployment Pipeline

We set up a fully automated deployment workflow using:

  • GitHub Actions or GitLab CI

  • Automatic build → test → deploy

  • Zero-downtime rolling deployment

  • Integration with:

    • EC2

    • ECS

    • Lambda

    • or S3 hosting

Deployment Pipeline Flow:

Commit → CI Build → Tests → S3/EC2/ECS Deployment → CloudFront Invalidation → Live

6. Cloud Security & Permissions

We applied strong security policies:

  • IAM least-privilege roles

  • Encrypted S3 buckets

  • HTTPS everywhere

  • Security Groups by IP

  • WAF + Shield (if required)

  • Route 53 DNSSEC optional setup

7. Monitoring & Alerts

We configured:

  • CloudWatch logs

  • CPU/memory alerts

  • Uptime monitoring

  • SNS notifications for failures

  • S3 metrics for storage cost optimization

📈 Results / Impact

🚀 Production-Ready Infrastructure in Days

The client launched quickly with a reliable professional-grade environment.

🔐 Secure & Compliant Setup

Secure DNS, backups, access control, and SSL everywhere.

👍 Zero-Downtime Deployment

New versions deployed smoothly using CI/CD.

💾 Automated Backup Pipeline

No manual backup work needed—fully scheduled & monitored.

💵 Cost-Optimized for Startups

  • S3 lifecycle rules lowered storage cost

  • Using AWS reserved/free-tier options

  • Efficient auto-scaling kept compute costs low

🌍 Scalable & Future-Proof

The setup supports:

  • Traffic spikes

  • Multiple environments

  • Global rollout
