S3 Quiz
An application allows users to upload images to an S3 bucket. Initially these images will be downloaded quite frequently, but after some time, the images might only be accessed once a week and the retrieval time should be as minimal as possible.
What could be done to ensure a COST effective solution? Choose 2 answers from the options below. Each answer forms part of the solution.
A. Storethe objects in Amazon Glacier.
B. Storethe objects in S3 – Standard storage.
C. Createa Lifecycle Policy to transfer the objects to S3 – Standard storage after acertain duration of time.
D. Createa Lifecycle Policy to transfer the objects to S3 – Infrequent Access storageafter a certain duration of time.
B. & D.
Store the images initially in Standard storage since they are accessed frequently. Define Lifecycle Policies to move the images to Infrequent Access storage to save on costs.
Amazon S3 Infrequent access is perfect if you want to store data that is not frequently accessed, and is must more cost-effective than Option D i.e. Amazon S3 Standard. Also, if you choose Amazon Glacier with expedited retrievals, you defeat the whole purpose of the requirement, because this option would result in increased costs.
