The 4-Week AWS Cloud Migration Playbook for Growing SaaS Teams

Every growing SaaS company hits a wall with shared hosting eventually. Slow queries, random downtime, no scalability. The next step — AWS — feels overwhelming. It shouldn’t be.

Week 1: Assessment. Map your current stack, identify dependencies and set up an AWS account with proper IAM. Bill under ₹5,000 this week.

Week 2: Foundation. VPC, subnets, security groups, RDS, S3, CloudFront, ACM. Everything infrastructure-as-code via Terraform.

Week 3: Migration. Deploy application to ECS Fargate or App Runner. Run in parallel with existing production. Point 5% of traffic. Monitor closely.

Week 4: Cutover. Gradually shift traffic 25% → 50% → 100% over 3 days. DNS TTL trick keeps rollback under 60 seconds.

The results: 99.99% uptime, sub-200ms response times, ability to scale from 10 to 10,000 users overnight, and cost that’s often lower than the old provider (thanks to right-sizing).

Skip the multi-month enterprise migration nightmare. In 4 focused weeks, you can be on world-class infrastructure.
