Exam AWS Certified Solutions Architect - Associate SAA-C03 topic 1 question 40 discussion

Definitely A, it's the most operationally efficient compared to D, which requires a lot of code and infrastructure to maintain. A is mostly managed (firehose is fully managed and S3 lifecycles are also managed)

Only A makes sense operationally. If you think D, just consider what is needed to move the message from SQS to S3... you are polling daily 14 TB to take out 1 TB... that's no operationally efficient at all.

I understand A is the most operationally efficient option of all but I can't wrap my head around the fact that objects must have a minimum of 30 days before they can transition or expire from Amazon S3. This means that for the first 30 days after an item is created, you cannot transition or remove it. So, how option A can be the best fit?

BCD: Additional infra which company doesn't want A: Firehose for ingestion and delivery to S3. Lifecycle for managing archive. Fully managed and operationally easy solution

Answer-A

so many words...

That was an easy A. Kinesis Firehose can load data directly to S3 which makes it the most operationally efficient

Key: MOST operationally efficient solution

"A" is simply correct because kinesis firehouse is made for this, SQS standard is not going to support 500 million alerts 2KB each (1 TB) this service is made for requests that are lighter.

I picked A. Appeared to be right answer.

Should be A

The MOST operationally efficient option is A.

Keyword "Amazon S3 Glacier" (A).

Option A is the right answer for this.

B suggests launching EC2 instances to ingest and store the alerts, which introduces additional infrastructure management overhead and may not be as cost-effective and scalable as using managed services like Kinesis Data Firehose and S3. C involves delivering the alerts to an Amazon OpenSearch Service cluster and manually managing snapshots and data deletion. This introduces additional complexity and manual overhead compared to the simpler solution of using Kinesis Data Firehose and S3. D suggests using SQS to ingest the alerts, but it does not provide the same level of data persistence and durability as storing the alerts directly in S3. Additionally, it requires manual processing and copying of messages to S3, which adds operational complexity. Therefore, A provides the most operationally efficient solution that meets the company's requirements by leveraging Kinesis Data Firehose to ingest the alerts, storing them in an S3 bucket, and using an S3 Lifecycle configuration to transition data to S3 Glacier for long-term archival, all without the need for managing additional infrastructure.

Focus on keywords: Amazon Kinesis Data Firehose delivery stream to ingest the alerts. S3 Lifecycle configuration to transition data to Amazon S3 Glacier after 14 days.
