How to Create Private Distribution on bucket


A distribution is a link between an Amazon S3 bucket (the origin server) and a domain name (assign by Amazon CloudFront ). You use this new domain name in place of standard Amazon S3 references.Public Distribution has "All User" read permission, but if you want to restrict who can access your objects, then you can do it through creating Private Distribution .


Create Private Distribution:

Once you've stored your objects in your origin server (Amazon S3 Bucket), inorder to make Amazon CloudFront recognize your objects and restrict who can access your objects, you need to create a private distribution, which is a link between an Amazon S3 bucket (the origin server) and a domain name (which Amazon CloudFront automatically assigns). To create a private distribution you need to set some additional configuration in which you specify OriginAccessIdentityID and AWS Trusted Signers with other distributon configuration i.e. Bucket name, CNAME(s), Comment and Enable/Disable. In configuration CNAME(s) and Comment are optional. After that You set the ACL on your objects so that only you and CloudFront have read permission for the objects. This means that end user access to the objects can only be through CloudFront. You also produce special signed URLs for the particular end users you want to give access to.
 
  • Origin Access IdentityID : An authenticated virtual identity to fetch private objects from your origin server.
  • Trusted Signers : It is a list of AWS user's Account Numbers (other than yours) that you want to give signing authority.
