<instructions>
Analyze the cloud infrastructure and provide comprehensive cost optimization recommendations:

1. COST ANALYSIS & VISIBILITY:
   - Current spend breakdown by service, team, and environment
   - Cost anomaly detection and trend analysis
   - Resource utilization metrics review
   - Cost allocation and tagging strategy assessment
   - Budget vs. actual spend variance analysis

2. COMPUTE OPTIMIZATION:
   - Right-sizing recommendations for EC2/VM instances
   - Spot/Preemptible instance adoption strategy
   - Reserved Instances and Savings Plans analysis
   - Container resource optimization (EKS/AKS/GKE)
   - Serverless cost efficiency review

3. STORAGE OPTIMIZATION:
   - Storage class tiering strategy (S3, Blob, GCS)
   - EBS/PD volume right-sizing and type optimization
   - Data lifecycle policies and archival
   - Snapshot and backup retention optimization
   - Deduplication and compression opportunities

4. NETWORKING COSTS:
   - Data transfer cost analysis
   - NAT Gateway optimization
   - CDN and caching strategy
   - VPC/VNet peering vs. transit alternatives
   - Direct Connect/ExpressRoute evaluation

5. DATABASE & ANALYTICS:
   - Database instance right-sizing
   - Read replica and caching strategy
   - Serverless database options (Aurora, Cosmos DB)
   - Data warehouse optimization (Redshift, BigQuery, Snowflake)
   - Query performance and indexing review

6. WASTE DETECTION & REMEDIATION:
   - Orphaned and unattached resource identification
   - Idle resource detection (load balancers, IPs, disks)
   - Zombie instance and snapshot cleanup
   - Over-provisioned development environments
   - Unused reserved capacity identification

7. GOVERNANCE & AUTOMATION:
   - Cost allocation tagging enforcement
   - Automated resource scheduling (start/stop)
   - Policy-based resource provisioning
   - Cost anomaly alerts and thresholds
   - Chargeback and showback implementation

8. OUTPUT FORMAT:
   - Executive summary with projected savings
   - Detailed recommendations prioritized by impact
   - Implementation roadmap with effort estimates
   - Terraform/CloudFormation/ARM templates for automation
   - Monitoring dashboards and alert configurations
