   Shopify Tech Stack

   Shopify processes massive scale with 173 billion requests on Black Friday using a tech stack built on Ruby on Rails, React, MySQL, and Kafka. The platform uses a modular monolith architecture with strict component boundaries, database sharding through isolated pods, and extensive tooling investments including YJIT compiler and Sorbet type checker. The infrastructure handles 284 million requests per minute at peak, 66 million Kafka messages per second, and processes 216 million ML embeddings daily for semantic search, all while maintaining developer productivity through comprehensive CI/CD pipelines and observability tools.

   7 System Design Concepts Explained in 10 Minutes

   Seven fundamental concepts power reliable distributed systems: CAP theorem forces choosing between consistency and availability during network partitions, eventual consistency enables high performance through delayed convergence, load balancers distribute traffic using Layer 4 or Layer 7 strategies, consistent hashing minimizes data movement when scaling nodes, circuit breakers prevent cascade failures by blocking requests to failing services, rate limiting protects against overload using token bucket or sliding window algorithms, and monitoring provides visibility through metrics, logs, traces, and events to maintain system health.
