AI, Identity & Enterprise Systems — explained visually.
See how modern systems actually work — how they connect, scale, secure access, and fail in production. Interactive lessons for engineers, architects, and anyone who wants to understand what happens under the hood.
Explore freely. No course order required.
Pick any part of the system
Every concept connects to something else. Start anywhere and follow the dependencies.
AI & Agent Systems
How language models actually work — from tokens and attention to inference, RAG, and the agent runtimes that wrap them. Start at intuition, end at production behavior.
20 lessonsWho is calling, and what may they doIdentity & Security
Principals, credentials, sessions, tokens, and the protocols that carry them — JWT, OAuth, OIDC, SAML, SCIM — through to workload identity, delegated authority, and agent identity.
15 lessonsDistributed systems that stay upEnterprise Systems
Distributed systems, caching, messaging, consistency, APIs, data architecture, and the observability that tells you whether any of it is working.
8 lessonsNamed solutions to recurring problemsArchitecture & Design Patterns
Circuit breakers, sagas, the outbox, bulkheads, idempotency, CQRS, and the other patterns you reach for when the diagram meets production.
12 lessonsNow break itFailure Modes
The ways systems actually fail: cascading failure, retry storms, cache stampedes, split brain, token replay, stale authorization. What triggers them, how they present, and how to contain the blast radius.
14 lessonsHow it works → how it connects → how it fails
Most sites explain what something is. Every Academy lesson answers what happens inside it, what it depends on, what trade-off it makes, and what happens when it fails.
