cloud-cost-optimization

## What I do - Analyze cloud spending patterns and identify waste - Implement cost optimization strategies across services - Design right-sizing policies for compute resources - Leverage reserved instances and savings plans - Implement auto-scaling and resource scheduling - Build cost allocation and showback models ## When to use me - When cloud costs are higher than expected - When you need to optimize existing cloud usage - When planning new cloud deployments on a budget - When implementing FinOps practices - When needing visibility into cloud spending - When allocating costs to teams or projects ## Key Concepts ### Cost Analysis Queries ```sql -- AWS Cost Explorer - Daily costs by service SELECT line_item_usage_start_date, line_item_product_code, SUM(line_item_unblended_cost) as cost FROM aws_cost_and_usage WHERE line_item_usage_start_date BETWEEN DATE_TRUNC('month', CURRENT_DATE) AND CURRENT_DATE GROUP BY 1, 2 ORDER BY 3 DESC; ``` ### Right-Sizing Recommendations ```python # GCP Recommender API example from google.cloud import recommender_v1 client = recommender_v1.RecommenderClient() project_id = "my-project" # Get idle resource recommendations recommendations = client.list_recommendations( parent=f"projects/{project_id}/locations/-/recommenders/" f"google.compute.instance.IdleResourceRecommender" ) for rec in recommendations: print(f"Recommendation: {rec.description}") print(f"Potential savings: {rec.primary_impact.cost_forecast.amount}") ``` ### Cost Optimization Strategies | Category | Strategy | Potential Savings | |----------|----------|-------------------| | Compute | Right-sizing instances | 20-40% | | Compute | Reserved/Savings Plans | 30-60% | | Storage | Lifecycle policies | 50-70% | | Data Transfer | CDN usage | 40-60% | | Database | Reserved instances | 30-50% | | Serverless | Pay-per-use optimization | 20-30% | ### Resource Scheduling ```yaml # Kubernetes pod scheduling for cost savings apiVersion: scheduling.k8s.io/v1 kind: PriorityClass metadata: name: low-priority value: -10 globalDefault: false description: "Non-production workloads" --- apiVersion: v1 kind: Pod metadata: name: batch-job spec: priorityClassName: low-priority tolerations: - key: "spot" operator: "Equal" value: "true" effect: "NoSchedule" ``` ### Budget Alerts ```hcl # Terraform AWS Budgets resource "aws_budgets_budget" "monthly" { name = "monthly-cost-budget" budget_type = "COST" limit_amount = "5000" limit_unit = "USD" time_period_start = "2024-01-01" time_unit = "MONTHLY" notification { comparison_operator = "GREATER_THAN" threshold = 80 threshold_type = "PERCENTAGE" notification_type = "FORECASTED" } } ``` ### FinOps Framework 1. **Inform**: Provide cost visibility to teams 2. **Optimize**: Act on optimization opportunities 3. **Operate**: Maintain cost efficiency over time 4. **Govern**: Establish policies and guardrails ### Key Metrics - Cost per user or transaction - Cost per environment (dev, staging, prod) - Idle resource percentage - Savings plan coverage - Resource utilization rates - Cloud waste percentage
