This project contains two versions of a similar app. The app is a feedback application that accepts comments and evaluates them using Amazon Comprehend to see if the feedback is positive, negativwe, or somewhere in between.
- AWS account configured for programatic access
- AWS SAM CLI v1.46.0+
- Docker
- Python 3.9+ (If you want to modify the code)
This version deploys an Amazon DynamoDB database and three AWS lambda functions. When a comment is written to the database, DynamoDB streams invokes a Lambda to call Amazon Comprehend, evaluate the comment, and write the results back to the database.
This version takes a low-code approach and uses AWS Step Functions to communicate with Amazon Comprehend and writes the data to Amazon DynamoDB. This example takes it a step further. If the feedback is positive, the comments are translated to Spanish and German to be shared with friends.
