Well-Architected, Migration and Cloud Economics
This topic covers the Well-Architected Framework, migration strategies, AWS CAF concepts, fixed versus variable costs, rightsizing, and automation value.
How to study for AWS Cloud Practitioner
Treat each question as a service-selection or responsibility decision: identify the business need, AWS responsibility, customer configuration, and best-fit service.
Core concepts
Concept 1
The AWS Well-Architected Framework organizes best practices across operational excellence, security, reliability, performance efficiency, cost optimization, and sustainability.
Exam cue: Map the issue to the most relevant Well-Architected pillar.
Concept 2
Migration decisions should consider business drivers, application dependencies, risk, cost, modernization goals, and migration strategy.
Exam cue: Choose migration support when the scenario is about cloud adoption journey.
Concept 3
Cloud economics includes rightsizing, managed services, automation, reduced data center burden, and usage-based pricing.
Exam cue: Use rightsizing and automation for cost and efficiency questions.
Risk pitfalls and guardrails
Calling every architecture issue a cost optimization problem.
Guardrail: Avoid answers that ignore customer configuration, choose unmanaged services when managed services fit, or use billing reports when proactive alerts are required.
Ignoring sustainability or operational excellence when a question is not purely technical.
Guardrail: Avoid answers that ignore customer configuration, choose unmanaged services when managed services fit, or use billing reports when proactive alerts are required.
Migrating without understanding dependencies or business goals.
Guardrail: Avoid answers that ignore customer configuration, choose unmanaged services when managed services fit, or use billing reports when proactive alerts are required.
