Cost Optimization

Optimization Strategies

1. Right-size instances
   - Monitor usage
   - Downsize underutilized
   - Use auto-scaling

2. Use Reserved/Spot instances
   - 1-year RI: 36% savings
   - 3-year RI: 57% savings
   - Spot: 70% savings (fault-tolerant)

3. Optimize storage
   - Use S3 for media
   - lifecycle policies
   - compression

4. Cache aggressively
   - Reduce database load
   - Fewer servers needed
   - CDN for static assets

5. Monitor and alert
   - Set budget alerts
   - Review monthly
   - Eliminate waste

Cost Monitoring

// Monthly cost review
$costBreakdown = [
    'compute' => $this->getComputeCosts(),
    'storage' => $this->getStorageCosts(),
    'network' => $this->getNetworkCosts(),
    'third_party' => $this->getThirdPartyCosts(),
    'total' => $total
];

// Compare to budget
$budget = 5000;
$variance = $total - $budget;
$variancePercent = ($variance / $budget) * 100;

// Alert if over budget
if ($variancePercent > 10) {

| Database (2x) | $365 | $4,380 |
| Redis (2x) | $184 | $2,208 |
| Storage | $63 | $756 |
| CDN | $100 | $1,200 |
| **Total** | **$1,208** | **$14,496** |

## Software
| Item | Annual |

| Performance | $20,000 |
| **Total** | **$120,000** |

## **Grand Total** | **$137,896** |

Cost Per Revenue Dollar

$revenue = 5000000; // $5M annual
$totalCost = 137896;
$costPerRevenueDollar = $totalCost / $revenue;
// = $0.028 per revenue dollar
// = 2.8% of revenue

// Industry benchmarks:
// Small store: 5-10% of revenue
// Medium store: 3-5% of revenue
// Large store: 1-3% of revenue

ROI Calculation

Basic ROI Formula

function calculateROI($investment, $return, $period) {
    $roi = (($return - $investment) / $investment) * 100;
    $annualizedROI = $roi / $period;
    
    return [
        'total_roi' => round($roi, 2),
        'annualized_roi' => round($annualizedROI, 2),
        'payback_period' => round($investment / ($return / $period), 1)
    ];
}

// Example: Upgrade investment
$investment = 50000;
$return = 150000; // over 3 years
$period = 3;

$result = calculateROI($investment, $return, $period);
// total_roi: 200%
// annualized_roi: 66.67%
// payback_period: 1 year

Business Value Metrics

$businessValue = [
    'performance' => [
        'improvement' => '20% faster page loads',
        'conversion_increase' => 0.05, // 5%
        'revenue_impact' => 5000000 * 0.05
    ],
    'reliability' => [
        'uptime_improvement' => '99.9% to 99.99%',
        'reduced_downtime' => 8, // hours per year
        'cost_avoided' => 8 * 1000 // $1000/hour lost sales
    ],
    'development' => [
        'productivity_increase' => 0.30, // 30%
        'developer_cost' => 100000, // per developer
        'savings' => 100000 * 0.30 * 3 // 3 developers, 3 years
    ]
];

$totalBusinessValue = 
    $businessValue['performance']['revenue_impact'] +
    $businessValue['reliability']['cost_avoided'] +
    $businessValue['development']['savings'];
// = 250000 + 8000 + 270000 = $528,000 over 3 years

Cost of Downtime

Revenue per hour: $5,000,000 / 365 / 24 = $571/hour

Downtime scenarios:
- 1 hour: $571
- 4 hours: $2,284
- 24 hours: $13,701
- Black Friday (4 hours): $5,000+

Prevention cost: $10,000/year monitoring
ROI of prevention: $50,000+ avoided losses
