Which storage solution is MOST cost-effective?
Create an S3 bucket lifecycle policy to move files from S3 Standard to S3 Glacier 30 days from object creation. Delete the files 4 years after object creation.
Create an S3 bucket lifecycle policy to move files from S3 Standard to S3 One Zone-Infrequent Access (S3 One Zone-IA) 30 days from object creation. Delete the files 4 years after object creation.
Create an S3 bucket lifecycle policy to move files from S3 Standard to S3 Standard-Infrequent Access (S3 Standard-IA) 30 days from object creation. Delete the files 4 years after object creation.
Create an S3 bucket lifecycle policy to move files from S3 Standard to S3 Standard-Infrequent Access (S3 Standard-IA) 30 days from object creation. Move the files to S3 Glacier 4 years after object creation.
Explanations:
S3 Glacier does not support immediate accessibility, which is required for these files. S3 Glacier has retrieval delays, making it unsuitable for immediate access.
S3 One Zone-IA is a lower-cost option but is only stored in a single Availability Zone, which does not meet durability requirements for critical business data.
S3 Standard-IA is a cost-effective choice for infrequently accessed data. It provides immediate access, high durability, and reduced costs after 30 days.
Moving data to S3 Glacier after 4 years would not be appropriate as the files should be deleted at this point per the policy.
As I recall, the answer is:
Create an S3 bucket lifecycle policy to move files from S3 Standard to S3 Standard-Infrequent Access (S3 Standard-IA) 30 days from object creation. Delete the files 4 years after object creation.
I reckon the answer is:
Create an S3 bucket lifecycle policy to move files from S3 Standard to S3 Standard-Infrequent Access (S3 Standard-IA) 30 days from object creation. Delete the files 4 years after object creation.
