Last Class 62nd Above service completed, using CloudFront Images stored in private bucket
It should retrieved from the s3 private bucket
Step1:
Need Create CloudFront distributed url select the Origin private while you creating
Step2: I have uploaded app_cloudfront.py take reference and execute rename app.py
>python app.py

Step3:Image column CloudFront, image stored database.
Step4: KMS , password encrypted
