Send books from Web to Kindle

Goal

The purpose of this overengineered project is to learn AWS and Python, nothing more. For that, I took a little practical idea of having an ability to send a book from [unnamed] site straight to my kindle and converted it to huge learning project.

The following technologies and languages were used during development:

• Python
• AWS, specifically:
  • Lambda
  • CodeBuild
  • API Gateway
  • IAM
  • RDS, specifically PostgreSQL.
  • S3
  • Secrets Manager
  • SNS (Simple Notifications Service)
  • SQS (Simple Queue Service)
• Serverless

Architecture

The solution consists of:

• Lambda triggered by API Gateway with POST to /books, which accepts JSON payload with which book to download and where to send it.
• Lambda that listens on queue, downloads a book and stores it on S3
• Lambda that listens on queue, and sends a book as attachment to mail address using SMTP server
• [Optional] PostgreSQL database that stores current state
• [Not implemented] Browser plugin that sends links to /books and initiates the whole process
