AWS Certified Solutions Architect – Professional (SAP-C02) — Question 511
A company wants to migrate its website to AWS. The website uses containers that are deployed in an on-premises, self-managed Kubernetes cluster. All data for the website is stored in an on-premises PostgreSQL database.
The company has decided to migrate the on-premises Kubernetes cluster to an Amazon Elastic Kubernetes Service (Amazon EKS) cluster. The EKS cluster will use EKS managed node groups with a static number of nodes. The company will also migrate the on-premises database to an Amazon RDS for PostgreSQL database.
A solutions architect needs to estimate the total cost of ownership (TCO) for this workload before the migration.
Which solution will provide the required TCO information?
Answer options
- A. Request access to Migration Evaluator. Run the Migration Evaluator Collector and import the data. Configure a scenario. Export a Quick Insights report from Migration Evaluator.
- B. Launch AWS Database Migration Service (AWS DMS) for the on-premises database. Generate an assessment report. Create an estimate in AWS Pricing Calculator for the costs of the EKS migration.
- C. Initialize AWS Application Migration Service. Add the on-premises servers as source servers. Launch a test instance. Output a TCO report from Application Migration Service.
- D. Access the AWS Cloud Economics Center webpage to assess the AWS Cloud Value Framework. Create an AWS Cost and Usage report from the Cloud Value Framework.
Correct answer: A
Explanation
Migration Evaluator is the recommended AWS service for creating a data-driven business case and estimating the Total Cost of Ownership (TCO) prior to a cloud migration by collecting on-premises utilization data. Other services like AWS DMS and AWS Application Migration Service are migration execution tools rather than pre-migration TCO estimation planning tools. The AWS Pricing Calculator can estimate costs but does not natively collect on-premises resource data to build a comprehensive TCO scenario report.
