A company is developing an application to support customer demands.The company wants to deploy the application on multiple Amazon EC2 Nitro-based instances within the same Availability Zone.The company also wants to give the application the ability to write to multiple block storage volumes in multiple EC2 Nitro-based instances simultaneously to achieve higher application availability.

Which solution will meet these requirements?

Use General Purpose SSD (gp3) EBS volumes with Amazon Elastic Block Store (Amazon EBS) Multi-Attach

Use Throughput Optimized HDD (st1) EBS volumes with Amazon Elastic Block Store (Amazon EBS) Multi-Attach

Use Provisioned IOPS SSD (io2) EBS volumes with Amazon Elastic Block Store (Amazon EBS) Multi-Attach

Use General Purpose SSD (gp2) EBS volumes with Amazon Elastic Block Store (Amazon EBS) Multi-Attach

Explanations:

General Purpose SSD (gp3) EBS volumes do support Multi-Attach, but they are not specifically designed for high availability and performance when used by multiple EC2 instances simultaneously compared to other options.

Throughput Optimized HDD (st1) EBS volumes are designed for throughput-intensive workloads but do not support Multi-Attach. Therefore, this option does not meet the requirement for multiple EC2 instances writing simultaneously.

Provisioned IOPS SSD (io2) EBS volumes support Multi-Attach and provide high availability and high performance for workloads that require high IOPS, making it ideal for the use case described.

General Purpose SSD (gp2) EBS volumes do not support Multi-Attach, which makes them unsuitable for the requirement of simultaneous writes by multiple EC2 instances.

    I plan that the answer is:
    Use Provisioned IOPS SSD (io2) EBS volumes with Amazon Elastic Block Store (Amazon EBS) Multi-Attach
