SAA-C03 Question 464
Single answerA company is running a batch processing application that handles large datasets and requires high memory capacity to perform in-memory computations efficiently. The application is CPU-intensive but benefits most from having a large memory footprint. Which instance type should the company choose to optimize performance and cost?
- A
Compute Optimized (C5)
- B
Memory Optimized (R5)
- C
Storage Optimized (I3)
- D
General Purpose (T4g)
Show answer and explanation
Correct answer: B
Explanation
Memory Optimized (R5) instances are the best choice for memory-intensive applications that require high memory capacity for in-memory computations. These instances provide the optimal memory-to-vCPU ratio, ensuring efficient processing of large datasets while keeping costs in check. Other instance families, like Compute Optimized or Storage Optimized, do not prioritize high memory capacity and would not be a cost-effective or performance-efficient choice for this workload.
- A. Incorrect.
Compute Optimized (C5) instances are designed for compute-intensive workloads like high-performance web servers and scientific modeling. They are not ideal for applications requiring high memory capacity.
- B. Correct.
Memory Optimized (R5) instances are specifically designed for memory-intensive workloads. They offer a high memory-to-vCPU ratio, making them well-suited for in-memory computations and handling large datasets.
- C. Incorrect.
Storage Optimized (I3) instances are designed for storage-heavy workloads and provide high disk throughput, but they are not optimized for memory-intensive applications.
- D. Incorrect.
General Purpose (T4g) instances provide a balanced ratio of compute, memory, and networking resources but are not specialized for high memory capacity required by in-memory computations.
