Cloud Cost Optimization

Multi-Cloud Cost Management

Terraform Cost Estimation

provider "infracost" {}

resource "aws_instance" "web_servers" {
  count         = var.environment == "prod" ? 3 : 1
  instance_type = var.environment == "prod" ? "t3.medium" : "t3.micro"
  
  tags = {
    Environment = var.environment
    CostCenter  = "web-${var.environment}"
  }
}

Cost Reporting Pipeline

    steps:

Cost Controls

AWS Budget Alert

resource "aws_budgets_budget" "cost_alert" {
  name         = "monthly-budget"
  budget_type  = "COST"
  limit_amount = "1000"
  limit_unit   = "USD"
  time_unit    = "MONTHLY"

  notification {
    comparison_operator = "GREATER_THAN"
    threshold          = 80
    threshold_type     = "PERCENTAGE"
    notification_type  = "ACTUAL"
  }
}
