Phase 3: Advanced Architecture & Optimization

This phase elevates your architectural thinking to the professional level, focusing on the cross-cutting concerns that define robust, enterprise-grade solutions. You will explore advanced strategies for resilience, cost optimization, security at scale, migration, and operational excellence. Mastery of these topics is essential for synthesizing comprehensive solutions that balance competing priorities, a key skill for the "SAP-C02" exam.

Scenario: Your company's initial "lift-and-shift" migration to AWS is complete. Now, as the lead architect, you are responsible for the next stage: optimizing the existing solutions for cost, enhancing their resilience to meet stricter SLAs, scaling security and governance, and planning the modernization of legacy components.

Reflection Question: How does the focus shift from "making it work" in the cloud to "making it work well"—that is, making it resilient, secure, cost-effective, and operationally excellent—as an architecture matures and moves beyond an initial "lift-and-shift"?
