You are requested to guide a large Pharma company. They are looking for a solution to save all their R&D test analysis data securely. Daily large numbers of reports are generated; this data would be accessed parallel from multiple R&D centers spread across the globe. The company requires this data to be instantaneously available to all users. Which of the following is the most suitable way for AWS storage to provide low latency access to users across the globe with the least cost?

Answer options:

A.Use Amazon EC2 instance with instance store to store data.
B.Use Amazon EFS volumes to store data.
C.Use Amazon EBS volumes connected to the EC2 instance to store data
D.Use Amazon S3 Buckets to store data.

Correct Answer – D
Amazon S3 can be used to store any amount of data that can be accessed from multiple locations concurrently without any impact on latency.
Option A is incorrect as the Instance store will provide low latency access from EC2 instances, but it’s a temporary storage option.
Option B is incorrect. Since this data would be accessed globally, Amazon EFS will not be ideal for this requirement.
Option C is incorrect as Amazon EBS volumes would be useful storage for single Amazon EC2 instances.
