Scaling Cloud Infrastructure on AWS & Kubernetes

When your SaaS platform expands from 1,000 to 100,000 active users, cloud infrastructure must scale gracefully without multiplying AWS monthly spending.

1. Infrastructure as Code (IaC) with Terraform

Never configure production cloud resources manually in the AWS Console. Using Terraform ensures every VPC network, security group, and EKS cluster is version-controlled and reproducible across staging environments.

2. Horizontal Pod Autoscaling (HPA)

Kubernetes HPA scales container pods dynamically based on CPU and memory thresholds, handling peak morning traffic spikes seamlessly.
