EFS / S3 file locking

[jgofaws]

Hello,

in the question 3 of this quizz https://portal.tutorialsdojo.com/courses/aws-certified-solutions-architect-associate-practice-exams/lessons/practice-exams-topic-based/quizzes/aws-certified-solutions-architect-associate-practice-exam-topic-based-efs/
it is stated in the answer that s3 does not provide file locking which is not true.
May be it could be interesting to add more details about the difference between S3 file locking and EFS regarding a use case like a CMS ?

Hello,

I can not add a snipet because when I press the button to add a picture nothing happens.
But I can copy you the text:

“<strong style=”font-family: inherit; font-size: inherit;”>Amazon S3 is incorrect. Although this provides the same level of high availability and high scalability like EFS, this service is not suitable for storing data that is rapidly changing, just as mentioned in the above explanation. It is still more effective to use EFS as it offers strong consistency and file locking, which the S3 service lacks.“
In my opinion the problem here is not file locking which s3 has but the files rapidly changing.

Hello jgofaws,

Thanks for the reply.

S3 is an object storage service, not a file system. It does not primarily support the NFSv4 protocol (explicitly mentioned in the scenario) or POSIX-compliant, making it unsuitable for EC2 instances that require file-based access. Additionally, while S3 does offer a feature called Object Lock for data immutability, it does not support file-level locking for concurrent file modifications, which is necessary for scenarios where multiple servers need to access and modify the same file simultaneously.

For more information about “Rapidly changing data”, please refer to this.

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