Correct answer & explanation
✓
Rehost (lift-and-shift) to Amazon EC2 using AWS Application Migration Service, then right-size instances and purchase Reserved Instances.
The most cost-effective strategy for a migration with underutilized on-premises infrastructure is to lift-and-shift to EC2, right-size the instances to match actual usage, and purchase Reserved Instances to save costs. This approach minimizes changes and leverages AWS discounts. Options A and B involve rearchitecting or replatforming which are more costly and time-consuming. Option D does not consider right-sizing and leads to overspending.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Refactor the application to run on containers using Amazon EKS with Fargate.
Why it's wrong here
Refactoring is expensive and may not be necessary for cost savings.
- ✗
Replatform the web tier to AWS Elastic Beanstalk and the database to Amazon RDS.
Why it's wrong here
Replatforming requires code changes and may not be the most cost-effective initially.
- ✓
Rehost (lift-and-shift) to Amazon EC2 using AWS Application Migration Service, then right-size instances and purchase Reserved Instances.
Why this is correct
Lift-and-shift is fast, and reserved instances reduce costs.
- ✗
Purchase compute-heavy EC2 instances to handle peak loads and use On-Demand pricing.
Why it's wrong here
Over-provisioning is costly; reserved instances with right-sizing are better.
