Architecture Scenario Simulator

A fashion e-commerce platform runs quarterly flash sales that drive 50x normal traffic for 2-hour windows. Last sale crashed after 15 minutes when traffic hit 500K concurrent users. Lost $2M in sales.

A healthcare analytics company needs to build a platform that ingests patient data from 50+ hospital systems, runs ML models for early disease detection, and provides dashboards to clinicians. Must be HIPAA compliant.

A logistics company managing 50,000 delivery vehicles needs a real-time fleet management platform. Current solution uses cellular modems sending data to on-premises servers, causing 30-minute delays in location updates and no predictive maintenance capabilities.

A digital advertising platform processing 500M events/day needs real-time analytics for campaign optimization. Current batch processing has 4-hour delay, causing advertisers to waste budget on underperforming campaigns.

A regional bank expanding nationally needs to meet regulatory requirements for business continuity. Current single-region deployment must be redesigned for <15 minute RTO and <1 minute RPO for critical banking services.

A project management SaaS that grew from 1,000 to 50,000 users in 18 months. The original architecture (monolith on Heroku) is showing cracks: slow deployments, database bottlenecks, and mounting costs.

A 40-year-old insurance company running critical policy systems on IBM mainframe (COBOL). Maintenance costs $8M/year, only 2 engineers understand the code, and integration with modern systems requires expensive middleware.

An educational video platform growing from 100K to 2M monthly active users. Current architecture streams directly from origin servers, causing buffering issues and $50K/month in bandwidth costs.

A B2B data management platform growing from 50 to 500 enterprise customers. Current single-tenant deployments are operationally unsustainable - each customer has separate infrastructure costing $2K/month to operate.
