First, let's implement the private APIs and services that provide common capabilities. We will have two services; both of them should be created in the chalicelib directory:
- StorageService: The StorageService class that's implemented in the storage_service.py file connects to AWS S3 via boto3 to perform tasks on files we need for the applications.
