When developing an application or service, one of the common questions we face is how many concurrent requests it can handle and how the services it depends on will respond. Even if we verify that all functionalities work correctly, this does not guarantee that the system will maintain its performance as demand increases.

This is why software testing goes beyond verifying functional requirements . It also allows us to evaluate aspects such as performance, stability, and responsiveness. In particular, load testing is not simply about pushing a system until it fails, but rather about understanding how it behaves under different conditions and identifying when it stops meeting the expected requirements.

In the previous article, we built a service to identify duplicate products using Amazon Bedrock, S3 Vectors, and DynamoDB, including an AWS Lambda function to perform real-time searches.…
