Cost Optimization Strategies

1. Right-Sizing Instances

Monitor and Adjust:

# AWS CloudWatch metrics
aws cloudwatch get-metric-statistics \
  --namespace AWS/EC2 \
  --metric-name CPUUtilization \
  --dimensions Name=InstanceId,Value=i-1234567890abcdef0 \
  --start-time 2026-01-01T00:00:00Z \
  --end-time 2026-01-31T23:59:59Z \
  --period 3600 \
  --statistics Average

Recommendations:

CPU < 20%: Downsize instance
CPU > 80%: Upsize or add instances
Memory < 30%: Reduce memory
Review monthly

2. Reserved Instances & Savings Plans

AWS Reserved Instances:

On-Demand: $0.0416/hour
1-Year Reserved: $0.0270/hour (35% savings)
3-Year Reserved: $0.0170/hour (59% savings)

Annual Savings:
1-Year: $1,280
3-Year: $2,160

When to Use:

Predictable workloads
Long-term commitment (1-3 years)
Production environments

3. Spot Instances

AWS Spot Instances:

Up to 90% discount
Can be terminated anytime
Good for batch processing, CI/CD

Use Cases:

Data processing
Machine learning training
CI/CD pipelines
Development environments

4. Auto-Scaling

Horizontal Scaling:

# AWS Auto Scaling configuration
AutoScalingGroup:
  MinSize: 2
  MaxSize: 10
  DesiredCapacity: 2
  TargetTrackingScaling:
    TargetValue: 70  # CPU percentage
    ScaleOutCooldown: 300
    ScaleInCooldown: 300

Benefits:

Pay only for what you use
Handle traffic spikes
Reduce costs during low traffic

5. Serverless Architecture

Cost Comparison:

Traditional Server:
- EC2 t3.small: $15/month (always running)
- Utilization: 10%
- Effective cost: $150/month per 10% usage

Serverless (Lambda):
- 1M requests: $0.20
- 400,000 GB-seconds: $6.67
- Total: ~$7/month
- Savings: 95%

When to Use Serverless:

Sporadic traffic
Event-driven workloads
Microservices
APIs with variable load

6. Storage Optimization

S3 Storage Classes:

Standard: $0.023/GB/month
Intelligent-Tiering: $0.023/GB (auto-optimize)
Infrequent Access: $0.0125/GB
Glacier: $0.004/GB
Deep Archive: $0.00099/GB

Example (1TB data):
Standard: $23/month
Glacier: $4/month
Savings: 83%

Lifecycle Policies:

{
  "Rules": [{
    "Id": "Archive old files",
    "Status": "Enabled",
    "Transitions": [
      {
        "Days": 30,
        "StorageClass": "STANDARD_IA"
      },
      {
        "Days": 90,
        "StorageClass": "GLACIER"
      }
    ]
  }]
}

7. CDN & Caching

Cloudflare Benefits:

Free tier available
Reduce origin requests by 80%
Lower bandwidth costs
Faster response times

Cost Savings:

Without CDN:
- 1TB bandwidth: $90 (AWS)

With Cloudflare:
- Cloudflare: $0 (free tier)
- Origin bandwidth: 200GB: $18
- Total: $18
- Savings: 80%

8. Database Optimization

Strategies:

Use read replicas for read-heavy workloads
Implement caching (Redis/Memcached)
Optimize queries
Use connection pooling
Archive old data

Cost Example:

Single RDS instance: $300/month

Optimized:
- Primary RDS: $150/month
- Read replica: $150/month
- Redis cache: $50/month
- Total: $350/month

But handles 5x more traffic!
Cost per request: 80% reduction

Security Best Practices

1. IAM & Access Control

Principle of Least Privilege:

{
  "Version": "2012-10-17",
  "Statement": [{
    "Effect": "Allow",
    "Action": [
      "s3:GetObject",
      "s3:PutObject"
    ],
    "Resource": "arn:aws:s3:::my-bucket/*"
  }]
}

Best Practices:

Use IAM roles, not root account
Enable MFA
Rotate credentials regularly
Use temporary credentials
Audit permissions quarterly

2. Network Security

VPC Configuration:

Public Subnet:
- Load Balancer
- NAT Gateway

Private Subnet:
- Application Servers
- Databases

Security Groups:
- Allow only necessary ports
- Restrict source IPs
- Use security group references

3. Data Encryption

Encryption at Rest:

Enable EBS encryption
S3 server-side encryption
RDS encryption
Use KMS for key management

Encryption in Transit:

Use HTTPS/TLS everywhere
VPN for private connections
SSL certificates (Let’s Encrypt)

4. Monitoring & Logging

Essential Monitoring:

Metrics:
- CPU, Memory, Disk usage
- Network traffic
- Error rates
- Response times
- Database connections

Logs:
- Application logs
- Access logs
- Error logs
- Security logs
- Audit logs

Tools:

CloudWatch (AWS)
Stackdriver (GCP)
Azure Monitor
Datadog (multi-cloud)
New Relic

Disaster Recovery

Backup Strategy

3-2-1 Rule:

3 copies of data
2 different storage types
1 offsite backup

Automated Backups:

# Daily database backup
aws rds create-db-snapshot \
  --db-instance-identifier mydb \
  --db-snapshot-identifier mydb-$(date +%Y%m%d)

# Retention policy
aws rds delete-db-snapshot \
  --db-snapshot-identifier mydb-$(date -d '30 days ago' +%Y%m%d)

Multi-Region Setup

Active-Passive:

Primary Region (us-east-1):
- Active application
- Primary database

Secondary Region (us-west-2):
- Standby application
- Database replica
- Automatic failover

RTO & RPO:

RTO (Recovery Time Objective): < 1 hour
RPO (Recovery Point Objective): < 15 minutes
