Question

A company hosts a multi-tier inventory reporting application on AWS. The company needs a cost-effective solution to generate inventory reports on demand. Admin users need to have the ability to generate new reports. Reports take approximately 5-10 minutes to finish. The application must send reports to the email address of the admin user who generates each report. Which solution will meet these requirements?

Accepted Answer

Let's map each requirement to the solution:

1. **Cost-effective**: AWS Lambda is pay-per-invocation with no idle costs. No need to manage or pay for containers/clusters running 24/7. This is the most cost-effective compute option for on-demand workloads.

2. **On-demand generation by admin users**: Lambda function URLs provide a dedicated HTTPS endpoint that admin users can invoke directly — no API Gateway needed, further reducing cost and complexity.

3. **5-10 minutes execution time**: Lambda supports up to **15 minutes** maximum timeout. A 5-10 minute report generation fits comfortably within this limit.

4. **Send reports to specific admin user's email**: Amazon SES is purpose-built for sending emails to **specific email addresses**. Unlike SNS (which sends to topic subscribers), SES
