AWS Certified Solutions Architect - Associate SAA-C03 — Topic 1 Question 300

Question

A company needs to migrate a legacy application from an on-premises data center to the AWS Cloud because of hardware capacity constraints. The application runs 24 hours a day, 7 days a week. The application’s database storage continues to grow over time. What should a solutions architect do to meet these requirements MOST cost-effectively?

Accepted Answer

Correct answer: C. The correct answer is C. Option C: Migrate the application layer to Amazon EC2 Reserved Instances. Migrate the data storage layer to Amazon Aurora Reserved Instances. Reserved Instances lower cost for steady-state, predictable long-running workloads. Amazon EC2 provides resizable virtual servers when you need full control of the operating system. Amazon Aurora is a high-performance managed relational database with built-in replication and failover. This option delivers the requirement at the lowest cost.
