* We will start with an API that allows to retrieve, create, update and delete expenses.
31+
* We will then create a second service that listens to these expense events, and keep a list of expense totals per person.
32+
33+
### Iterations
34+
35+
1. Define some domain classes with tests
36+
2. Create a simple AWS Lambda function that returns mocked expense data
37+
1. Implement a simple way of testing the lambda function
38+
3. Add an AWS API Gateway endpoint to call the Lambda function and test that via Postman
39+
4. Create a new API endpoint with Lambda function for creating & updating expenses
40+
5. Persist the expenses to DynamoDB and change Lambda to use the persisted data
41+
6. Create a Lambda function that listens to expense events via AWS Simple Notification Service and keep track of expense totals per person - show how it behaves via AWS Cloudwatch
42+
7. (if time) hook up API Gateway endpoint to expense totals lambda
