Large-Scale Systems

Large-Scale Systems follows one four-tier system, browser to web app to business app to database, from a single server to a global fleet. Forty-six episodes, one idea each: replication, sharding, load balancing, the laws that cap concurrency, caching, failure and the nines, security end to end, deployment from hand-built boxes to Kubernetes, the products that implement all of it, and the foundations that tie it together. Every pattern is named with the trade it actually costs. Two hosts, no slides, no exam.
