Interactive MicroSims
Interactive simulations to help product managers build technical fluency through hands-on exploration.
-
Simulate a full A/B test experiment to see why sample size matters, how confidence builds over time, and what happens when you stop early.
-
Availability & Downtime Calculator
Explore how uptime percentages translate to real downtime and revenue impact. Compare "nines" of availability from 90% to 99.9999% and understand the engineering cost at each tier.
-
Interactive p5.js simulation demonstrating the REST API request and response cycle. Explore HTTP methods, endpoints, status codes, and request/response bodies.
-
Build SQL queries visually against a sample database with Customers, Orders, and Products tables. Learn SELECT, WHERE, ORDER BY, and JOIN by constructing queries and seeing the results.
-
Database Normalization Visualizer
Watch a denormalized table transform through 1NF, 2NF, and 3NF step by step. See redundant data highlighted and anomalies resolved at each stage.
-
Monolith vs. Microservices Explorer
Adjust team size, system complexity, and expected users to see the architecture visually morph between monolith, modular monolith, and microservices with contextual recommendations.
-
Send animated traffic at servers and toggle between vertical and horizontal scaling strategies. Watch vertical scaling hit the hardware ceiling while horizontal scaling keeps adding instances.
-
Play through 12 sprints choosing to ship fast or refactor. Watch how technical debt compounds into delivery slowdowns and compare your strategy against a balanced team.
-
Classify real-world product scenarios into the correct architecture pattern: monolithic, microservices, SOA, or distributed system. An interactive quiz with hints and explanations.
