AWS Cost Optimization & Resource Cleanup

The Challenge

A digital media production company found themselves facing unexpected AWS charges despite believing their cloud resources were dormant. After transitioning away from an active project, they continued receiving monthly bills with no clear visibility into what resources were consuming costs. The situation required:

• Complete audit of all AWS services across multiple regions
• Identification of forgotten or orphaned resources
• Safe deletion of unnecessary infrastructure without data loss
• Implementation of cost controls to prevent future unexpected charges
• Documentation of the cleanup process for future reference

Our Solution

We implemented a comprehensive AWS cost optimization strategy, combining automated tools with manual verification to ensure complete resource cleanup while maintaining data safety.

Discovery & Assessment

• Performed multi-region service inventory across all AWS availability zones
• Identified active S3 buckets containing millions of archived objects
• Discovered forgotten compute resources and storage volumes
• Mapped resource dependencies to ensure safe deletion order
• Documented all findings for client transparency

Technical Implementation

• Deployed AWS Nuke for automated resource cleanup
• Created custom scripts for S3 bucket versioning cleanup
• Implemented region-specific deletion strategies to minimize scan time
• Configured termination protection overrides for stubborn resources
• Established verification checkpoints throughout the process
• Built safeguards to prevent accidental deletion of critical resources

Process Optimization

1. Initial Assessment: Comprehensive scan of 15+ AWS regions to identify active resources
2. Resource Categorization: Classified resources by service type and deletion priority
3. Automated Cleanup: Deployed Infrastructure as Code solutions for systematic resource removal
4. Manual Verification: Double-checked critical services requiring special handling
5. Cost Validation: Verified successful cost optimization across all regions

Results

The optimization project delivered immediate and measurable improvements:

• Significant Cost Reduction: Dramatically reduced recurring AWS charges
• 15 Regions Audited: Comprehensive assessment across global infrastructure
• Millions of Objects Processed: Identified and cleaned up archived S3 data
• Zero Data Loss: Maintained data integrity throughout the process
• Complete Documentation: Provided detailed cleanup records for compliance
• Ongoing Savings: Prevented accumulation of unnecessary charges

Key Achievements

• Immediate Impact: Cost reductions visible from the first billing cycle
• Risk Mitigation: Addressed security concerns from unmaintained resources
• Knowledge Transfer: Educated client on AWS cost management best practices
