Question

A company is migrating a data processing application to AWS. The application processes several short-lived batch jobs that cannot be disrupted. The process generates data after each batch job finishes running. The company accesses the data for 30 days following data generation. After 30 days, the company stores the data for 2 years. The company wants to optimize costs for the application and data storage. Which solution will meet these requirements?

Accepted Answer

**Answer D satisfies every requirement:**

1. **"Cannot be disrupted" → EC2 On-Demand Instances**: On-Demand Instances guarantee that your instance will not be interrupted by AWS. Spot Instances can be reclaimed with 2-minute notice, which violates the requirement.

2. **"Accesses data for 30 days" → S3 Standard**: During the first 30 days, data is actively accessed. S3 Standard provides low-latency, high-throughput access with no retrieval fees — ideal for frequent access.

3. **"Stores data for 2 years after 30 days" → S3 Glacier Deep Archive**: After 30 days, the data is only stored (not actively accessed). S3 Glacier Deep Archive is the cheapest storage class (~$0.00099/GB/month), perfect for long-term archival where immediate retrieval is not needed.

4. **"Delete after 2 years" → S3
