CloudThinker Use Case: Global AWS FinOps & Cost Optimization

The Challenge

In multi-region AWS environments, operational costs often spiral out of control due to several common issues:

• Underutilized EC2 instances: Running with average CPU utilization <5%
• Orphaned EBS volumes: Unattached volumes and snapshots older than 90 days
• Idle Elastic IPs: Unassociated IP addresses still incurring charges
• Unoptimized S3 buckets: No Intelligent-Tiering or lifecycle policies implemented

The Result: AWS costs can increase 20–30% monthly without proper visibility and control mechanisms.

The CloudThinker Solution

CloudThinker performs automated discovery across 21 AWS regions, delivering comprehensive visibility into your cloud estate:

Discovery Results

• 107 AWS resources inventoried and analyzed
• 31 optimization opportunities identified
• Potential savings: $1,956/month (~$23,500/year)

Specific Optimization Recommendations

Storage Optimization

• S3 Intelligent-Tiering: Reduce ~20–30% storage costs through automated storage class transitions
• 2 idle EBS volumes (508GB total): Save ~$50.8/month
• Snapshot cleanup: Remove snapshots older than 90 days no longer needed

Compute Optimization

• Rightsize EC2 m5.xlarge: Instance with 0.2% CPU utilization → downsize to save ~$120/month
• Reserved Instances: Convert On-Demand to RIs for stable workloads
• Spot Instances: Apply to non-production and batch workloads

Network Optimization

• 6 unassociated Elastic IPs: Release to save ~$21.6/month
• Cross-region transfer analysis: Optimize data transfer costs

Quantified Results

FinOps Dashboard

CloudThinker provides a comprehensive FinOps Dashboard with critical visualizations:

   • Compare cost distribution across locations

2. Cost by Service (pie chart)

   • EC2: 45%
   • RDS: 25%
   • S3: 15%
   • Other services: 15%

3. Top 10 Cost Drivers (table)

   • Detailed breakdown of most expensive resources
   • Specific action items for each resource

4. Current vs Optimized (stacked bar comparison)

   • Visualize savings potential
   • Breakdown by service category

5. Monthly Projection (trendline)

   • Forecast costs before/after optimization
   • Track progress over time

AI-Powered FinOps Prompt

You are a FinOps & Cloud Optimization Expert.

Analyze my entire AWS environment across all regions and all services,
and propose cost optimization actions. In addition to structured
recommendations, also create a visual dashboard to summarize cost insights.

Context:

• Scope: All AWS resources, all regions, all services
• Constraints:
  • No downtime for production workloads (09:00–21:00 local time)
  • No data loss
  • SLA: web latency p99 < 200ms, RDS CPU < 70%
• Goal: minimize AWS bill globally, provide executive visibility

Instructions:

1. Perform a global scan and identify:

• Idle or underutilized resources
• Orphaned resources (unattached volumes, idle ELB, unused IPs, snapshots)
• Overprovisioned resources

1. Recommend pricing model optimizations:

• Savings Plans, Reserved Instances, Spot Instances
• Consolidated billing opportunities

1. Optimize storage & networking:

• S3 storage class transitions
• Snapshot and backup cleanup
• Cross-region transfer analysis

1. Prioritize recommendations with:

• Resource/Service + Region
• Suggested Change
• Estimated Saving ($ and %)
• Risk/Trade-off
• Implementation Steps (CLI/Console/IaC hint)

1. Provide a global roadmap (Quick Wins → Medium-term → Long-term).

2. Create a FinOps Dashboard with:

• Cost by Region (bar chart)
• Cost by Service (pie chart)
• Top 10 most expensive resources (table)
• Projected savings after optimization
• Trend chart (monthly cost projection before/after)

1. Conclude with top 3 highest ROI actions and estimated new
   global AWS monthly cost.

Implementation Roadmap

Quick Wins (Week 1-2)

• Release 6 unassociated Elastic IPs → $21.6/month
• Delete 2 idle EBS volumes → $50.8/month
• Enable S3 Intelligent-Tiering → $300-400/month

Medium-term (Month 1-3)

• Rightsize EC2 instances → $120/month
• Implement Reserved Instances for stable workloads → $400/month
• Cleanup old snapshots → $50/month

Long-term (Month 3-6)

• Adopt Savings Plans strategically → $200/month
• Implement Spot Instances for batch workloads → $150/month
• Optimize cross-region data transfer → $100/month

Top 3 Highest ROI Actions

1. S3 Intelligent-Tiering

• Effort: Low (1-2 hours)
• Savings: $300-400/month
• Risk: None (AWS-managed)
