Challenges
  • Overprovisioned on-prem servers with unpredictable growth.
  • No IAM discipline — shared credentials, wide-open security groups.
  • Zero observability once workloads left the datacenter.
Solutions
  • Designed multi-AZ VPC with public/private subnets and NAT egress.
  • Introduced least-privilege IAM roles, MFA on root, and SCPs.
  • Right-sized EC2 instances with reserved + spot mix; S3 lifecycle policies for archival.
  • Hooked CloudWatch metrics, logs and alarms into the existing on-call flow.
Business Impact

40% infrastructure cost reduction, elastic scalability, hybrid connectivity to on-prem.
