When to use Same-Region Replication Same-Region Replication (SRR) is used to copy objects across Amazon S3 buckets in the same AWS Region. SRR can help you do the following: Aggregate logs into a single bucket – If you store logs in multiple buckets or across multiple accounts, you can easily replicate logs into a single, in-Region bucket. Doing so allows for simpler processing of logs in a single location. Configure live replication between production and test accounts – If you or your customers have production and test accounts that use the same data, you can replicate objects between those multiple accounts, while maintaining object metadata. Abide by data sovereignty laws – You might be required to store multiple copies of your data in separate AWS accounts within a certain Region. Same-Region Replication can help you automatically replicate critical data when compliance regulations don't allow the data to leave your country.

Same-Region Replication (SRR) works ONLY on new objects uploaded AFTER enabling the service on a S3 bucket. It does not work on existing objects in the bucket.

Correct Answer: B "Posted On: Sep 18, 2019 Amazon S3 introduces Same-Region Replication: Amazon S3 now supports automatic and asynchronous replication of newly uploaded S3 objects to a destination bucket in the same AWS Region." Ref: https://aws.amazon.com/about-aws/whats-new/2019/09/amazon-s3-introduces-same-region-replication/

B for sure, i found the answer in the official documntation.

Documentation states the use case clearly: Same-Region Replication (SRR) is used to copy objects across Amazon S3 buckets in the same AWS Region. SRR can help you do the following: Aggregate logs into a single bucket — If you store logs in multiple buckets or across multiple accounts, you can easily replicate logs into a single, in-Region bucket. This allows for simpler processing of logs in a single location. https://aws.amazon.com/about-aws/whats-new/2019/09/amazon-s3-introduces-same-region-replication/

IMO: A because all proposals can do cross-account (IAM role/trust) so its only about cost: if lifecycle also changes storage class its unbeatable. API bulk is second.

B. https://aws.amazon.com/about-aws/whats-new/2019/09/amazon-s3-introduces-same-region-replication/

With S3 Replication, you can configure cross account replication where the source and destination buckets are owned by different AWS accounts. Excluding S3 storage and applicable retrieval charges, customers pay for replication PUT requests and inter-region Data Transfer OUT from S3 to your destination region when using S3 Replication. If you have S3 Replication Time Control (S3 RTC) enabled on your replication rules, you will see a different Data Transfer OUT and replication PUT request charges specific to S3 RTC. For cross account replication, the source account pays for all data transfer (S3 RTC and S3 CRR) and the destination account pays for the replication PUT requests. Data transfer charges only apply for S3 Cross Region Replication (S3 CRR) and S3 Replication Time Control (S3 RTC), there are no data transfer charges for S3 Same Region Replication (S3 SRR). Visit the S3 pricing page for more details on S3 Replication pricing.

Amazon S3 now supports automatic and asynchronous replication of newly uploaded S3 objects to a destination bucket in the same AWS Region. Amazon S3 Same-Region Replication (SRR) adds a new replication option to Amazon S3, building on S3 Cross-Region Replication (CRR) which replicates data across different AWS Regions. Together, SRR and CRR form Amazon S3 Replication to deliver enterprise-class replication features such as cross-account replication for protection against accidental deletion and replication to any Amazon S3 storage class, including S3 Glacier and S3 Glacier Deep Archive to create backups and long-term archives. With SRR, new objects uploaded to an Amazon S3 bucket are configured for replication at the bucket, prefix, or object tag levels. Replicated objects can be owned by the same AWS account as the original copy or by different accounts, to protect from accidental deletion

B is correct.

most cost-effective and serves the purpose.

the answer is b. https://docs.aws.amazon.com/AmazonS3/latest/userguide/replication-walkthrough-2.html

Form me answer B : SRR -> "Amazon S3 now supports automatic and asynchronous replication of newly uploaded S3 objects to a destination bucket in the same AWS Region. " https://aws.amazon.com/about-aws/whats-new/2019/09/amazon-s3-introduces-same-region-replication/?nc1=h_ls

Answer is D

I go for D. A & B are for the same account. C will copy all the data which might be replicated.
