The context
In this illustrative scenario, a B2B application stores documents uploaded by clients and files generated by the product. A growing customer base brings more stored data and downloads. The product team wants to keep user journeys smooth while giving engineering and finance teams clearer visibility into storage usage and costs.
The problem to solve
Files sometimes share resources with the rest of the application, and their cost is difficult to connect to client usage. Access controls, temporary links and automated processing create dependencies that need to be tested before the storage layer can change.
The proposed mission
- 01
Map file types, their lifecycles and access journeys, then select a pilot use case based on the impact it will have on the product and engineering.
- 02
Test the S3 functions used by the application, access rights and download mechanisms, then measure performance under a load representative of the usage the team expects.
- 03
Plan the transfer and cutover of the validated scope, add monitoring for errors and volumes, then document retention rules and ongoing operations for the responsible team.
Intended benefits
- Storage costs that are easier to connect to client usage and data volumes.
- A planned transition with verified application journeys and clearly defined responsibilities for delivery.
- Retention rules that support the growing volume of files stored by the product.
How to measure the outcome
- Storage cost per active client
- File journey latency
- Upload and download error rate
The baseline and objectives are defined during scoping, then compared with pilot results.
