Building Scalable Infrastructure with Kubernetes & Terraform

Modern DevOps workflows require reproducible, reliable, and automated infrastructure management. Combining Terraform for Infrastructure as Code (IaC) and Kubernetes for container orchestration provides a powerful foundation for cloud-native applications.

Why Infrastructure as Code?

Infrastructure as Code allows teams to declare infrastructure configuration in version-controlled files rather than manual point-and-click console operations. Key benefits include:

• Version Control: Every change is tracked in Git.
• Consistency: Environments (Dev, Staging, Prod) are identical.
• Speed: Provisioning complex cloud infrastructure takes minutes instead of hours.

# Example Terraform snippet for VPC provisioning
resource "aws_vpc" "main" {
  cidr_block           = "10.0.0.0/16"
  enable_dns_hostnames = true

  tags = {
    Name = "production-vpc"
  }
}

Container Orchestration with Kubernetes

Once infrastructure is provisioned, Kubernetes manages containerized application lifecycles, self-healing, scaling, and rolling updates.

Best Practices

1. Resource Limits & Requests: Always specify CPU and Memory bounds for pods.
2. Health Checks: Configure Liveness and Readiness probes to prevent routing traffic to unhealthy containers.
3. CI/CD Integration: Automate deployment using GitOps tools like ArgoCD or GitHub Actions.
