Answer: Amazon EC2

## Explanation **Amazon EC2 (Elastic Compute Cloud)** is the correct choice for this workload because: 1. **Infrequent Processing**: The requirement is to perform data processing only once a week, which means the company doesn't need a continuously running service. 2. **On-Demand Compute**: EC2 provides virtual servers that can be started when needed, used for the data processing task, and then stopped to avoid unnecessary costs. 3. **Cost Optimization**: With EC2, the company can use Spot Instances or On-Demand Instances and only pay for the compute time actually used during the weekly processing. 4. **Flexibility**: EC2 allows running various data processing applications, scripts, or tools that the company might need. **Why the other options are incorrect**: - **AWS CodeDeploy**: This is a deployment service for automating application deployments to various compute services, not a data processing service. - **Amazon Neptune**: This is a graph database service, not suitable for general data processing workloads. - **AWS Wavelength**: This is a service for deploying applications at the edge of 5G networks to reduce latency, not designed for periodic data processing. **Best Practice**: For truly periodic workloads like this, the company could also consider using AWS Lambda (serverless compute) triggered by Amazon EventBridge (CloudWatch Events) on a weekly schedule, which would be even more cost-effective for short-running tasks. However, among the given options, EC2 is the most appropriate choice.
