In one sentence
Use global infrastructure, shared responsibility, security, core services, billing, and support plans as the final-review path.
Key points
- Order: global infrastructure and shared responsibility → IAM/security → EC2/S3/RDS/VPC/Lambda → billing tools → support plans.
- SQL, joins, and transactions → RDS/Aurora; key-value, serverless, and low latency → DynamoDB.
- Multi-Region active-active → DynamoDB Global Tables; microsecond DynamoDB cache → DAX.
- Complex JSON or MongoDB compatibility → DocumentDB; relationship graphs → Neptune; migration → DMS; heterogeneous conversion → SCT.
One-minute billing and support review
- Current bill and payments → Billing Dashboard; actual or forecast thresholds → AWS Budgets.
- Historical cost, trends, and forecasts → Cost Explorer; pre-deployment estimate → Pricing Calculator.
- Multi-account payment and eligible aggregated discounts → Organizations consolidated billing.
- Project, department, or environment ownership → activated cost-allocation tags.
- Right-sizing advice → Compute Optimizer; broad best-practice checks → Trusted Advisor.
- Third-party software, AMIs, and SaaS → Marketplace; AWS partners → APN.
- Basic has no technical-case SLA; Enterprise emphasizes a TAM; response targets do not guarantee resolution.
Exam focus
- CLF emphasizes service purpose, responsibility boundaries, and cloud business value rather than every implementation detail.
Common pitfalls
- Do not choose by product name alone; confirm data type, latency, control, operations, and cost constraints.
Remember
Finish with infrastructure, responsibility, security, core services, cost, and support.
One-minute migration and specialist-service addendum
- Three phases: Assess → Mobilize → Migrate & Modernize; the 7Rs decide each application’s treatment.
- Evaluator builds the business case, Discovery finds dependencies, Transform MGN moves servers, DMS moves databases, and DataSync moves files.
- AppSync means GraphQL, Amplify is the frontend full-stack platform, Connect is the contact center, and SES sends application email.
- WorkSpaces provides a full desktop, WorkSpaces Applications streams apps, and Secure Browser provides only an isolated browser session.
