Answer - B.

Amazon S3 is the default storage service that should be considered for companies.

It provides durable storage for all static content.

For the given scenario, Amazon S3 (Simple Storage Service) is the most appropriate option to store static content for the three-tier, highly available web application.

Amazon S3 provides a durable and scalable object storage service that can store and retrieve any amount of data from anywhere on the web. S3 is designed to deliver 99.999999999% durability, and data is automatically replicated to multiple AWS Availability Zones (AZs) within a region to ensure high availability.

Since S3 is a fully managed service, it doesn't require any infrastructure management, and it provides better performance at a lower cost compared to other storage options like EBS volumes or EC2 instance store.

EBS volumes are block-level storage devices that are attached to EC2 instances, providing high-performance storage with low latency. However, EBS volumes are not suitable for storing static content as they are designed for block storage and require an EC2 instance to be mounted and accessed.

EC2 instance store provides temporary block-level storage that is directly attached to the EC2 instance. It is a low-latency and high-throughput storage option, but it is not suitable for storing static content as it provides temporary storage, which means that data stored in instance store volumes is lost if the instance is stopped or terminated.

Amazon RDS is a managed relational database service that provides scalable and reliable database instances. While RDS provides durable storage for database instances, it is not an appropriate option for storing static content.

In summary, for durable storage of static content while utilizing lower Overall CPU resources for the web tier, the best option is to use Amazon S3.
