Project overview

Safe Button is a Flask application built around a simple daily check-in workflow. The project explores how the same application idea can be deployed using two different cloud platforms, with each implementation using its own identity, storage, and delivery services.

Cloud implementations

Google Cloud

The main branch contains the Flask check-in app and a Cloud Build workflow. The check-in sends a timestamped email through configurable SMTP settings.

AWS

The AWS branch adds Cognito sign-in and per-user DynamoDB records, with an EKS deployment pipeline built from CodePipeline and CodeBuild.
