Cost Optimization

Automated tooling to reduce cloud spend for GistPin infrastructure.

Scripts

Script Purpose
infrastructure/scripts/optimize-costs.sh Orchestrates all cost checks and produces a JSON report
infrastructure/scripts/find-idle-resources.sh Detects idle k8s pods, scaled-down deployments, unbound PVCs, and idle EC2 instances

Usage

# Run full cost optimisation analysis
bash infrastructure/scripts/optimize-costs.sh

# Scan for idle resources only
bash infrastructure/scripts/find-idle-resources.sh

Reports are written to infrastructure/reports/cost/cost-report-<timestamp>.json.

Configuration

Variable Default Description
REPORT_DIR infrastructure/reports/cost Output directory for reports
IDLE_CPU_THRESHOLD 5 CPU % below which a resource is considered idle
IDLE_MEM_THRESHOLD 10 Memory % below which a resource is considered idle
ENVIRONMENT unknown Label written into the report

Requirements

  • jq — JSON processing
  • kubectl + metrics-server — for Kubernetes checks (optional)
  • AWS CLI with ce:GetReservationCoverage permission — for RI analysis (optional)

Recommendations workflow

  1. Run optimize-costs.sh on a schedule (e.g. weekly cron).
  2. Review the generated report and the idle-resource output.
  3. Right-size or terminate identified resources.
  4. Re-run to confirm savings.
