S3 Quiz
A storage solution is required in AWS to store videos uploaded by the user. After a period of a month, these videos can be deleted. How should this be implemented in an cost-effective manner?
A. Use EBS Volumes to store the videos. Create a script to delete the videos after amonth.
B. Use transition rule in S3 to move the files to Glacier and use expiration rule to delete it after 30 days.
C. Store the videos in Amazon Glacier and then use Lifecycle Policies.
D. Store the videos using Stored Volumes. Create a script to delete the videos after amonth.
B. Use transition rule in S3 to move the files to Glacier and use expiration rule to delete it after 30 days.
AWS Documentation mentions the following on Lifecycle Policies:
Lifecycle configuration enables you to specify the lifecycle management of objects in a bucket. The configuration is a set of one or more rules, where each rule defines an action for Amazon S3 to apply to a group of objects. These actions can be classified as follows:
Transition actions – In which you define when objects transition to another storage class. For example, you may choose to transition objects to the STANDARD_IA (IA, for infrequent access) storage class 30 days after creation, or archive objects to the GLACIER storage class one year after creation.
Expiration actions – In which you specify when the objects expire. Then Amazon S3 deletes the expired objects on your behalf.

Note: Yes, if we delete the data within 30 days, we will incur certain charges. And the question says that “How should this be implemented in an cost-effective manner?” The charge which is going to incur because of not storing data for 90 days in Glacier is would be less than storing in S3.
Further, in the given options we need to choose the cost-effective option, that doesn’t mean it has to be the most cost-effective.
