Description

Your assessment is to design and build a currency exchange tracking application in the AWS lambda environment.

The application should rely on European Central Bank Data.

Exchange rates should be fetched every day and stored in a database.

The application should expose a public REST API endpoint that provides current exchange rate information for all tracked currencies and their change compared to the previous day for all the tracked currencies.

Business Requirements

  • As an API Client, I want to see current exchange rates.

  • As an API Client, I want to understand how the exchange rate has changed compared to the previous day.

Technical Requirements

  • The application should be written in python 3.9

  • The application can only use the following AWS Services:

    • AWS Lambda
    • AWS CloudFormation
    • AWS SQS
    • AWS SNS
    • AWS Cloudwatch
    • AWS API Gateway
    • AWS S3
    • AWS DynamoDB
    • AWS Log Insights

  • Delivered code and documentation SHOULD follow the best practices

  • Application must be fully functioning

  • Application must be deployable (either to AWS or localstack )

You can use cloudformation, CDK, serverless or AWS CLI for the deployment.
