Engineered for immediate execution. All tactics proven in production at 100+ companies.

The Reality: 73% of AWS workloads are overprovisioned (Flexera 2024). Follow these steps to reclaim your budget:

Step 1: Deploy Spot Instances Like a Pro (Save 70-90%)

Target: Stateless workloads (batch jobs, containers, CI/CD, analytics).

The Execution Plan:

1. Identify Candidates:

   • Run: aws cloudwatch get-metric-data --metric-name CPUUtilization --namespace AWS/EC2

   • Target workloads with <60% CPU + fault tolerance (e.g., Kafka consumers).

2. Configure Spot Fleet:

    aws ec2 request-spot-fleet --spot-fleet-request-config file://config.json
   

   Sample config.json: Diversify across 4+ instance types (e.g., m5.large, c5.xlarge) in 2 AZs.

3. Automate Recovery:

   • Use EC2 Auto Scaling + CloudWatch: Restart interrupted jobs.

   • For Kubernetes: Install Karpenter (auto-provisions replacements in <60 sec).

✅ Production Result: AdTech firm reduced 18,000 core/hour analytics cost from $1,200/day → $263/day.
⚠️ Avoid: Databases, stateful services.

Step 2: Automate Non-Prod Shutdowns (Save 65% Overnight)

Target: Dev/QA environments running 24/7.

The Execution Plan:

1. Tag Resources:

    aws ec2 create-tags --resources i-1234567890abcdef0 --tags Key=Schedule,Value=mon-fri-9to5
   

2. Deploy Lambda Scheduler:

   • Use AWS Instance Scheduler (pre-built CloudFormation template).

   • Set schedules: {"weekdays": {"start": "09:00", "stop": "17:00"}}

3. Exempt Critical Resources:

   • Add tag: "Schedule": "exclude" to prod databases.

✅ Production Result: SaaS company saved $18,000/month auto-stopping 287 dev instances nights/weekends.

Step 3: Rightsize Relentlessly (Save 20-50% Per Instance)

Stop paying for idle capacity.

The Execution Plan:

1. Find Waste:

   • AWS Compute Optimizer → "Under-provisioned Recommendations".

   • Target: Instances with avg CPU <40% + RAM <50% over 14 days.

2. Downsize Strategically:

   • Before: m5.4xlarge ($0.768/hr)

   • After: m5.2xlarge ($0.384/hr) → Saves 50%

3. Upgrade Generations:

   • Switch Intel → Graviton (e.g., c6g.4xlarge): 20% cheaper + 40% better perf.

4. Optimize Storage:

   • Migrate gp2 → gp3 volumes:

       aws ec2 modify-volume --volume-id vol-12345 --volume-type gp3 --iops 5000 --throughput 250
     

✅ Production Result: Media company cut $14,000/month by downsizing 73 overprovisioned RDS/EC2 instances.

Step 4: Eliminate Orphaned Resources (Save 5-15% "Silent Tax")

Zombie resources draining $1,000s monthly.

The Execution Plan:

1. Run Detection Scripts:

    # Find unattached EBS volumes:
    aws ec2 describe-volumes --filters Name=status,Values=available --query "Volumes[*].VolumeId"
   

2. Automate Deletion:

   • Deploy Cloud Custodian policy:

    policies:
      - name: delete-unattached-ebs
        resource: ebs
        filters:
          - Attachments: []  # Unattached volumes
        actions:
          - type: delete

3. Clean S3:

   • Enable S3 Lifecycle Rules: Delete incomplete multipart uploads after 1 day.

✅ Production Result: E-commerce platform recovered $5,200/month deleting 2,400 old snapshots + 17 idle load balancers.

Step 5: Strategic Savings Plans (Save 72% Like Enterprise)

Better than RIs: Flexible across instance families.

The Execution Plan:

1. Analyze Usage:

   • Cost Explorer → "Savings Plans Recommendations".

   • Target: Baseline steady-state workloads (e.g., always-on APIs).

2. Buy Compute Savings Plan:

   • Commit to $20/hr for 1 year → get 72% discount on covered usage.

3. Layer with Spot:

   • Use Savings Plans for 60% baseline, Spot for 40% variable spikes.

✅ Production Result: Gaming studio paid $0.08/hr (vs. $0.30/hr) for 50,000 core-hours/day.

Your 30-Day Implementation Roadmap

1. Week 1:

   • Enable Cost Explorer + Compute Optimizer.

   • Tag all non-prod resources.

2. Week 2:

   • Deploy Spot Fleet for 1 workload (start with CI/CD).

   • Launch Lambda scheduler for dev envs.

3. Week 3:

   • Rightsize 5 worst-sized instances.

   • Run Cloud Custodian cleanup.

4. Week 4:

   • Purchase Savings Plan for top steady workload.

Expected Results:

• Month 1: 15-25% savings

• Month 3: 40-60% savings

Critical Avoidances

❌ Never run Spot for stateful services
❌ Don’t downsizing during peak loads
❌ Test GP3 volumes before mass migration

Tool Stack:

• Visibility: Cost Explorer, CloudHealth

• Automation: Cloud Custodian, Instance Scheduler

• Optimization: Compute Optimizer, Karpenter
