Price Comparison Examples

Example 1: Simple Web Application

const requirements = { compute: '2 x t3.medium (24/7)', storage: '100GB SSD', database: 'PostgreSQL (db.t3.medium)', traffic: '1TB/month egress', };

const costs = { aws: { ec2: 2 * 0.0416 * 730 = 60.74, ebs: 100 * 0.10 = 10, rds: 49.64 + (20 * 0.115) = 51.94, transfer: 1000 * 0.09 = 90, total: 212.68, }, azure: { vm: 2 * 0.0416 * 730 = 60.74, disk: 100 * 0.048 = 4.80, sql: 406, // Managed SQL more expensive transfer: 1000 * 0.087 = 87, total: 558.54, }, gcp: { compute: 2 * 0.0335 * 730 = 48.91, disk: 100 * 0.17 = 17, sql: 30.15 + (20 * 0.17) = 33.55, transfer: 1000 * 0.12 = 120, total: 219.46, }, };

// Winner: AWS ($212.68/month) // With Reserved Instances (1yr): $140/month (34% savings)

Example 2: Serverless API

const requirements = { requests: '50M/month', avgDuration: '200ms', avgMemory: '512MB', };

const lambda = { requests: 50 * 0.20 = 10, compute: 50e6 * 0.5 * 0.2 * 0.0000166667 = 83.33, total: 93.33, };

const azureFunctions = { executions: 50 * 0.20 = 10, compute: 50e6 * 0.5 * 0.2 * 0.000016 = 80, total: 90, };

const cloudFunctions = { invocations: 50 * 0.40 = 20, compute: 50e6 * 0.5 * 0.2 * 0.0000025 = 12.5, networking: 1000 * 0.12 = 120, // 1TB egress total: 152.50, };

// Winner: Azure Functions ($90/month)
