Exam AWS Certified Solutions Architect - Associate SAA-C03 topic 1 question 890 discussion

A company needs to optimize its Amazon S3 storage costs for an application that generates many files that cannot be recreated. Each file is approximately 5 MB and is stored in Amazon S3 Standard storage.

The company must store the files for 4 years before the files can be deleted. The files must be immediately accessible. The files are frequently accessed in the first 30 days of object creation, but they are rarely accessed after the first 30 days.

Which solution will meet these requirements MOST cost-effectively?

  • A. Create an S3 Lifecycle policy to move the files to S3 Glacier Instant Retrieval 30 days after object creation. Delete the files 4 years after object creation.
  • B. Create an S3 Lifecycle policy to move the files to S3 One Zone-Infrequent Access (S3 One Zone-IA) 30 days after object creation. Delete the files 4 years after object creation.
  • C. Create an S3 Lifecycle policy to move the files to S3 Standard-Infrequent Access (S3 Standard-IA) 30 days after object creation. Delete the files 4 years after object creation.
  • D. Create an S3 Lifecycle policy to move the files to S3 Standard-Infrequent Access (S3 Standard-IA) 30 days after object creation. Move the files to S3 Glacier Flexible Retrieval 4 years after object creation.

Selected Answer: A
Although it's not stated what is meant by 'rarely accessed', this scenario would primarily be a candidate for the Glacier Instant Retrieval tier as the storage price would be more than 3 times lower compared to Standard IA. In the specific case of files being more frequently retrieved than quarterly, it can qualify for consideration of Standard IA. Actually, we don't have the required info, so we have to guess what they are thinking.. which is pretty lame, to be honest..

S3 Glacier Instant Retrieval only retain the file for maximun 90 days, that is why A is not correct answer. So C is right answer.

The 90-day minimum storage duration means that if you delete, overwrite, or transition an object before 90 days, AWS will charge you for the remaining unused storage days. It's a bit confusing but it's not like you can only have the files for 90 days, all glaciers are intended to retain data for archival purposes and 4 years as the question says is archival.

No, it isn't. It is just the opposite. Objects archived to S3 Glacier Flexible Retrieval have a minimum of 90 days of storage. If an object is deleted, overwritten, or transitioned before 90 days, a pro-rated charge equal to the storage charge for the remaining days will be incurred. https://aws.amazon.com/s3/faqs/?nc=sn&loc=7

Hell no. S3 Glacier Instant Retrieval is designed for long-lived, rarely accessed data that is retained for months or years. Objects that are archived to S3 Glacier Instant Retrieval have a minimum of 90 days of storage

B is out! store the files for 4 years before the files can be deleted - for long term we should use S3 Glacier Instant Retrieval. files are frequently accessed in the first 30 days of object creation, it actually store in Amazon S3 Standard storage

Each file is approximately 5 MB and is stored in Amazon S3 Standard storage, meaning when file created .. files already store in Amazon S3 Standard storage.. move to move the files to S3 Glacier Instant Retrieval 30 days after object creation is fine...

Selected Answer: C
Option C is correct instead of A because S3 Standard-IA provides lower long-term storage costs with immediate access, whereas S3 Glacier Instant Retrieval has higher retrieval costs, making it less cost-effective for files that may still need to be accessed occasionally.

Selected Answer: A
Glacier is much cheaper for storage than standard. The catch is you have to pay for 90 days of storage no matter what, even if the object is deleted. Here we will store data for 4 years so glacier is the cheapest solution.

Selected Answer: C
A - S3 Glacier Instant Retrieval is designed for archival storage where objects are infrequently accessed but still require millisecond retrieval, so yes actually A will work. It's just that Glacier storage costs more than S3 Standard-IA (given that after 30 days, the files are only RARELY accessed), so this is not the most cost-effective option. B - For files that "cannot be recreated," durability is crucial, so single Availability Zone is not OK. C - S3 Standard-IA is optimized for objects accessed less frequently but still requires rapid retrieval and high durability. D - After 4 years, let's just delete those files.

Just a thought, if not constrained to these option, I would simply use Intelligent-Tiering to automatically move the files between access tiers (frequent access, infrequent access, etc) based on actual usage. Eventually, I'd delete these files after 4 years as well. I think this approach is better.

Selected Answer: C
AnswerC We cannot choose B because if that one zone will fail, company will not be able to recreate them. We cannot choose D because we do not have to store files after 4y hence we can delete them (cost savings) We cannot choose A - Glacier is less expensive (0,004 per GB) then S3-Standard - IA but is not allowing for instant access which is one of requirements (there is no information that data access shouldn't be accessible immedietly) we have only information that after 30d access to data is less frequently. Hence I think we need to choose S3 Standard - IA (answer C)

Requirements: - frequently accessed for 30 days - lower cost Features for S3 Standard-IA: - Infrequently accessed objects - Milliseconds to acces According to me, best option for this use case is C NB: Glacier better suits for lower cost, infrequent access.
