💡 Quick Wins (Immediate Impact)​

1. Right-Size Your EC2 Instances​

The Problem: Over-provisioned instances waste money The Solution: Match instance size to actual usage

# Check CPU utilization
aws cloudwatch get-metric-statistics \
  --namespace AWS/EC2 \
  --metric-name CPUUtilization \
  --dimensions Name=InstanceId,Value=i-1234567890abcdef0 \
  --start-time 2024-01-01T00:00:00Z \
  --end-time 2024-01-31T23:59:59Z \
  --period 3600 \
  --statistics Average

CloudWise Cost Visibility:

  • Shows EC2 spending trends and patterns
  • Identifies EC2 as a cost optimization priority when it represents high spending
  • Provides cost breakdowns to help you focus optimization efforts on highest-cost instances

Manual Implementation: Use CloudWise cost data to identify high-cost EC2 services, then use AWS CloudWatch or CLI commands above to analyze utilization and resize instances.

Typical Savings: 20-50% on compute costs

2. Clean Up Unused Resources​

Common Waste Sources:

  • Unattached EBS volumes
  • Unused Elastic IP addresses
  • Forgotten load balancers
  • Unused NAT Gateways
  • Old snapshots and AMIs

CloudWise Cost Insights: CloudWise shows cost data that can help identify potential unused resources:

  • Unexpected charges that might indicate forgotten resources
  • Cost patterns that could suggest resource cleanup opportunities
  • Service costs that warrant investigation

Manual Investigation: Use AWS Console, CLI, or AWS Config to identify and safely delete unused resources. CloudWise cost data can guide where to look first.

Typical Savings: $50-500/month

3. Optimize S3 Storage Classes​

Storage Class Optimization:

  • Standard → Standard-IA: 40% savings after 30 days
  • Standard-IA → Glacier: 70% savings for archival data
  • Intelligent Tiering: Automatic optimization

CloudWise Analysis: CloudWise identifies storage cost patterns that may benefit from optimization:

  • High S3 costs from Standard storage class
  • Storage services with optimization potential
  • Cost trends indicating storage lifecycle opportunities

Implementation: Use AWS S3 Console or CLI to implement lifecycle policies and Intelligent Tiering based on CloudWise cost analysis.

📊 Medium-Impact Optimizations​

4. Reserved Instances & Savings Plans​

Reserved Instances (RIs):

  • 1-year term: 30-40% discount
  • 3-year term: 50-60% discount
  • Must commit to specific instance type/region

Savings Plans (Recommended):

  • More flexible than RIs
  • Apply to any instance family/region
  • Covers Lambda, Fargate, and more

CloudWise Cost Analysis: CloudWise can show you historical spending patterns that may indicate Reserved Instance opportunities:

  • Consistent month-over-month compute spending
  • EC2 costs that could benefit from commitment discounts
  • Services with predictable usage patterns suitable for reservations

Analysis: Use CloudWise cost history combined with AWS Cost Explorer's RI recommendations to make informed decisions.

5. Database Cost Optimization​

RDS Optimization:

  • Right-size database instances
  • Use Reserved Database Instances
  • Consider Aurora Serverless for variable workloads

DynamoDB Optimization:

  • On-Demand vs Provisioned pricing
  • Global Secondary Index optimization
  • DynamoDB Accelerator (DAX) evaluation

Example Optimization:

📊 RDS Cost Analysis
Current: db.r5.2xlarge (On-Demand) = $1,200/month
Recommended: db.r5.xlarge (1-year RI) = $420/month
Monthly Savings: $780 (65% reduction)

6. Network Cost Optimization​

Data Transfer Costs:

  • Minimize cross-region transfers
  • Use CloudFront for content delivery
  • Implement VPC endpoints

Common Optimizations:

  • CloudFront: $0.085/GB vs EC2 data out $0.09/GB
  • VPC Endpoints: Eliminate NAT Gateway costs
  • Region consolidation: Keep related resources together

⚡ Advanced Optimization Strategies​

7. Automated Scheduling​

Instance Scheduling:

  • Dev/test environments: 40 hours/week vs 168 hours/week
  • Potential savings: 75% on non-production workloads

Implementation Options:

# AWS Instance Scheduler
aws instancescheduler create-schedule \
  --name "dev-hours" \
  --timezone "America/New_York" \
  --periods "workdays:09:00-18:00"

CloudWise Cost Insights:

  • Shows cost trends that may help identify scheduling opportunities
  • Displays spending patterns across different time periods
  • Helps estimate potential savings from reduced operating hours

Implementation: Use AWS Instance Scheduler or similar tools to implement scheduling based on CloudWise cost analysis.

8. Containerization & Serverless​

Container Optimization:

  • ECS/EKS: Better resource utilization
  • Fargate: No instance management overhead
  • Spot pricing for batch workloads

Serverless Migration:

  • Lambda: Pay-per-execution model
  • Aurora Serverless: Scale to zero capability
  • DynamoDB On-Demand: No capacity planning

Cost Comparison:

Traditional Setup:
- 3x m5.large (24/7) = $378/month
- Load balancer = $25/month
Total: $403/month

Serverless Alternative:
- Lambda (1M requests) = $20/month
- API Gateway = $35/month
Total: $55/month (86% savings)

9. Multi-Account Strategy​

Account Separation Benefits:

  • Isolate costs by environment/team
  • Apply different optimization strategies
  • Better resource governance

AWS Organizations Setup:

  • Consolidated billing across accounts
  • Service Control Policies (SCPs)
  • Centralized Reserved Instance benefits
