A financial firm, which has a web server in an EC2 Instance, is developing a new web application with static informational content and dynamic functional content with server-side scripting. They expect heavy traffic on the launch of the application. The dynamic content should be stored as files in a file system. The storage of static content should be highly available and cost-effective. Which of the following solutions is the most suitable?

Answer options:

A.Use Amazon EFS for dynamic content & Amazon S3 for static content.
B.Use Amazon EBS for dynamic content & Amazon EFS for static content.
C.Use Amazon S3 for dynamic content & Amazon EBS for static content.
D.Use Amazon Instance Store for dynamic content & Amazon S3 for static content

Correct Answer – A
For websites with dynamic user interactions, using Amazon EFS is an ideal option to use along with using Amazon S3 for static non-changing data. EFS provides a scalable, distributed file system solution where dynamic content can be stored and scaled elastically allowing parallel access from EC2 instances while S3 is best suited for storing & serving static content using a CloudFront distribution
Option B is incorrect as EBS is for block storage, not suitable for storing dynamic content. EFS can be used to store static content but it is not cost-efficient as S3.
Option C is incorrect as Amazon S3 cannot be used for dynamic content. Amazon EC2 or EFS can be used.
Option D is incorrect as Amazon Instance Store is temporary storage and is not suited for dynamic web content.
