Explanation

For CPU-intensive workloads, Compute Optimized instances are the most appropriate choice. Here's why:

EC2 Instance Type Characteristics:

1. Compute Optimized Instances (Correct Answer):

   • Designed for compute-bound applications

   • Feature high-performance processors

   • Ideal for batch processing, media transcoding, high-performance computing (HPC), scientific modeling, and gaming servers

   • Examples: C5, C6g, C6i instances

2. General Purpose Instances:

   • Provide a balance of compute, memory, and networking resources

   • Suitable for a wide variety of workloads

   • Not optimized specifically for CPU-intensive tasks

   • Examples: T3, M5, M6g instances

3. Memory Optimized Instances:

   • Designed for memory-intensive applications

   • Feature high memory-to-CPU ratios

   • Ideal for in-memory databases, real-time big data analytics, and high-performance caching

   • Examples: R5, X1, X2gd instances

4. Storage Optimized Instances:

   • Designed for workloads that require high, sequential read/write access to large datasets

   • Feature high disk throughput

   • Ideal for NoSQL databases, data warehousing, and log processing

   • Examples: I3, D2 instances

Key Takeaway:

When selecting EC2 instance types, always match the instance family to the primary resource requirement of your workload:

• CPU-intensive → Compute Optimized

• Memory-intensive → Memory Optimized

• Storage-intensive → Storage Optimized

• Balanced workloads → General Purpose

This ensures optimal performance and cost-efficiency for your specific use case.
