Question #1402
A company is migrating an enterprise database system from its on-premises infrastructure to AWS. The database uses a licensing model based on physical sockets and cores, with strict performance and uptime requirements. The company aims to reuse its existing licenses, which are bound to specific hardware configurations and were recently renewed. Which Amazon EC2 pricing option provides the MOST cost-effective solution?
Dedicated On-Demand Hosts
Dedicated Reserved Instances
Dedicated Reserved Hosts
Dedicated On-Demand Instances
Explanation
The correct answer is C. Dedicated Reserved Hosts. Here's why:
- Licensing Requirements: The database licenses are tied to physical hardware (sockets/cores). Dedicated Hosts provide visibility into the physical server, ensuring compliance with licensing terms.
- Cost Efficiency: Reserved Hosts offer up to 70% savings over On-Demand pricing via 1- or 3-year commitments, aligning with the company's recent license renewal and long-term usage.
- Why Not Other Options:
- A/D (On-Demand Hosts/Instances): More expensive than Reserved options and do not provide long-term cost savings.
- B (Dedicated Reserved Instances): Reserved Instances apply to instance capacity, not physical hosts. They don't address hardware-bound licensing requirements.
Key Points: Use Dedicated Hosts for hardware-bound licenses; Reserved pricing for cost savings. Reserved Hosts combine both benefits.
Answer
The correct answer is: C
