Important points to remember

  • Buckets are a universal namespace, i.e., the bucket names must be unique.
  • If uploading of an object to S3 bucket is successful, we receive a HTTP 200 code.
  • S3, S3-IA, S3 Reduced Redundancy Storage are the storage classes.
  • Encryption is of two types, i.e., Client Side Encryption and Server Side Encryption
  • Access to the buckets can be controlled by using either ACL (Access Control List) or bucket policies.
  • By default buckets are private and all the objects stored in a bucket are also private.
