Explanation
Amazon EC2 (Elastic Compute Cloud) is the correct choice for this workload because:
- Infrequent Processing: The requirement is to perform data processing only once a week, which means the company doesn't need a continuously running service.
- 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.
- 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.
- 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.
