AWS Certified Developer Associate DVA-C02 Practice Question

For applications that are computationally intensive, the primary performance bottleneck is typically the processing power of the compute resources. Therefore, allocating a sufficient number of processing units (vCPUs) is the most critical factor for efficient performance.

• Elastic Load Balancer throughput is relevant for handling high volumes of incoming network traffic, not for accelerating the calculations themselves.
• Database read replicas help scale read-heavy database workloads, which is an optimization for database I/O, not for CPU-bound tasks.
• Provisioned IOPS for storage is critical for applications with high disk read/write requirements, but it does not address the needs of an application whose main workload is in-memory computation.
