Question Discrepancy – ALB Mentioned, ELB in Answers

[Offeki]

Hi everyone,

I came across the following question in the “CSAA – Design High-Performing Architectures” category and noticed a potential discrepancy that I wanted to discuss:

Question:

A large telecommunications company needs to run analytics against all combined log files from the Application Load Balancer as part of the regulatory requirements.

Which AWS services can be used together to collect logs and then easily perform log analysis?<source-footnote ng-version=”0.0.0-PLACEHOLDER” _nghost-ng-c800995309=””><sup _ngcontent-ng-c800995309=”” data-turn-source-index=”1″></sup></source-footnote><sources-carousel-inline ng-version=”0.0.0-PLACEHOLDER” _nghost-ng-c2168857225=””> <sources-carousel _ngcontent-ng-c2168857225=”” hide-from-message-actions=”” _nghost-ng-c213497774=””></sources-carousel></sources-carousel-inline>

Amazon DynamoDB for storing and EC2 for analyzing the logs.

Amazon S3 for storing the ELB log files and an EC2 instance for analyzing the log files using a custom-built application.

Amazon S3 for storing ELB log files and Amazon<source-footnote ng-version=”0.0.0-PLACEHOLDER” _nghost-ng-c800995309=””><sup _ngcontent-ng-c800995309=”” data-turn-source-index=”2″></sup></source-footnote> Athena for analyzing the log files.<sources-carousel-inline ng-version=”0.0.0-PLACEHOLDER” _nghost-ng-c2168857225=””> <sources-carousel _ngcontent-ng-c2168857225=”” hide-from-message-actions=”” _nghost-ng-c213497774=””></sources-carousel></sources-carousel-inline>

Amazon EC2 with EBS volumes for storing and analyzing the log files.

My concern lies in the fact that the question specifically mentions Application Load Balancer (ALB), but the correct answer (and one of the incorrect ones) refers to storing ELB (Elastic Load Balancer) log files.

Could this be an oversight in the question? While the combination of S3 and Athena is indeed a good solution for analyzing load balancer logs in general, the specific mention of ALB versus ELB in the options seems inaccurate.

I’m curious to hear your thoughts on this. Is there a nuance I might be missing, or is this likely a case of inconsistent terminology?

Thanks in advance for your input!

Hello Offeki,

Thanks for the feedback.

The terminology around “ELB log files” is used in AWS documentation. ELB generates access logs containing detailed information about requests processed by your load balancer.

For more details, please refer to this: https://docs.aws.amazon.com/elasticloadbalancing/latest/application/load-balancer-access-logs.html#access-log-file-format

Hope this helps! Let us know if you need further assistance.
