Invoice or statement with the cost of determined EC2 instances in a time period in PDF format

Unfortunately, there isn't a direct built-in option in AWS to generate a PDF report specifically for selected EC2 instances over a specific time period in the format you're describing. However, there are some alternative approaches you can consider:

1. Using Amazon QuickSight: You can create a custom dashboard in QuickSight that displays cost information for your selected EC2 instances over the desired time period. Once created, you can export this dashboard as a PDF. This method allows you to visualize and present the data in a format similar to what you're looking for.

2. AWS Cost Explorer: While not exactly in PDF format, you can use Cost Explorer to filter and view costs for specific EC2 instances over a given time period. You can then export this data, although it would be in CSV format rather than PDF.

3. Custom Solution: For a more tailored approach, you could create a custom program using the AWS SDK (such as boto3 for Python) to fetch EC2 instance cost data for your selected instances and time period, then generate a PDF report.

4. Cost and Usage Reports (CUR): You can use CUR in combination with Amazon Athena to query specific EC2 instance costs over a given time period. While this doesn't directly produce a PDF, you can export the results and convert them to PDF format.

5. Third-Party Tools: Some third-party tools offer advanced monitoring and reporting for EC2 instances, including exportable reports in PDF format that might meet your needs.

While these methods don't provide an exact replica of the billing PDF for selected EC2 instances, they offer ways to capture and present the essential cost information for your specified EC2 instances over a given time period in a format that can be easily shared or archived. If you need the exact format of the AWS billing PDF, you may need to reach out to AWS Support for further assistance or explore more advanced custom solutions.
