Chapters
Migration and Modernization Decisions — select change strategies and sequence dependencies safely.
High Availability, Disaster Recovery, and Cost Trade-Offs — align resilience investment with business impact.
SaaS and Multi-Tenant Architecture — design tenant context, isolation, scaling, observability, and cost allocation.
AWS Architecture Brainstorming Scenarios — practice discovery, option comparison, and risk narration.

How the Chapters Connect
