Real-World Architecture Scenarios
This part applies the earlier mental models, service choices, and patterns to one connected commerce domain. The scenarios show how business journeys and failure consequences reshape a design.
What You Will Learn
Move from requirements and constraints to a target architecture.
Compose synchronous, asynchronous, data, AI, and integration patterns.
Make consistency, latency, security, reliability, and cost trade-offs visible.
Explain how connected systems evolve without losing ownership or evidence.
Chapters
Core E-Commerce Platform — design storefront, API, order, inventory, data, and operational paths.
AI Workloads in E-Commerce — add recommendations, search, assistants, grounding, evaluation, and safety.
Back-Office Automation and Inventory — coordinate inventory and fulfillment through reliable workflows.
Enterprise Integration in E-Commerce — connect internal, partner, and legacy systems through governed contracts.
Payments, Billing, and Settlement Engine — design idempotency, reconciliation, audit, and financial correctness.
How the Chapters Connect
The core platform supplies the business spine. AI, operations, enterprise integration, and payments then add progressively stronger data, coordination, safety, and correctness requirements.
