Answer: Establish a private S3 bucket with an OAI policy for CloudFront access and AWS CLI for content uploads.
Option C is the correct answer. Using an Amazon S3 bucket is a cost-effective solution because S3 handles static content very efficiently without the need for managing servers. By making the bucket private and using an S3 bucket policy to only allow access from a CloudFront origin access identity (OAI), the setup becomes both secure and resilient. Content updates can be managed using the AWS CLI, which integrates well with S3. This approach eliminates the need for maintaining virtual servers (as in Option A and B) and makes the website hosting process simpler and more scalable.
