From Config to Cloud A Pythonic Approach to Platform Independent Design
summary
A runnable loan decision app is deployed on AWS EKS with Terraform and duplicated Terraform for GCP, demonstrating stateless microservices as Docker images and a vendor-agnostic shim implemented in config.py exposing insert_to_object_store so the same code switches between boto3 and Google client libraries. GitHub Actions provide a sync S3 to GCS workflow to copy recent objects for failover. Databases remain hard: the demo works for UI/API and object storage but full DB migration is left to incremental syncs and acceptable data-loss windows.
