Your team has deployed an application that consists of a web and database tier hosted on separate EC2 Instances. Both EC2 Instances are using General Purpose SSD for their underlying volume type. Of late, there are performance issues related to the read and writes of the database EC2 Instance. Which of the following could be used to alleviate the issue?

Answer options:

A.Change the Instance type to a higher Instance Type.
B.Change the EBS volume to Provisioned IOPS SSD.C.Enable Enhanced Networking on the Instance.
D.Enable Multi-AZ for the database.

Answer – B
The Provisioned IOPS SSD EBS volume type is perfect for these types of workloads. The below excerpt from the documentation shows the key differences between the different volume types.
Option A is incorrect since the primary issue is that the volume type is not correct.
Option C is incorrect since networking is not an issue here.
Option D is incorrect since this option is applicable for the AWS RDS service.
