Topic 1 Question 175
A company has an application that runs as a ReplicaSet of multiple pods in an Amazon Elastic Kubernetes Service (Amazon EKS) cluster. The EKS cluster has nodes in multiple Availability Zones. The application generates many small files that must be accessible across all running instances of the application. The company needs to back up the files and retain the backups for 1 year.
Which solution will meet these requirements while providing the FASTEST storage performance?
Create an Amazon Elastic File System (Amazon EFS) file system and a mount target for each subnet that contains nodes in the EKS cluster. Configure the ReplicaSet to mount the file system. Direct the application to store files in the file system. Configure AWS Backup to back up and retain copies of the data for 1 year.
Create an Amazon Elastic Block Store (Amazon EBS) volume. Enable the EBS Multi-Attach feature. Configure the ReplicaSet to mount the EBS volume. Direct the application to store files in the EBS volume. Configure AWS Backup to back up and retain copies of the data for 1 year.
Create an Amazon S3 bucket. Configure the ReplicaSet to mount the S3 bucket. Direct the application to store files in the S3 bucket. Configure S3 Versioning to retain copies of the data. Configure an S3 Lifecycle policy to delete objects after 1 year.
Configure the ReplicaSet to use the storage available on each of the running application pods to store the files locally. Use a third-party tool to back up the EKS cluster for 1 year.

EFS = Fastest storage performance compare to S3/EBS

Explanation: Amazon EFS provides shared file storage that is highly available and durable. It is an ideal solution to share files between containers running on multiple instances in a cluster. Mounting an Amazon EFS file system on each subnet provides a shared file system for multiple instances running in different Availability Zones. Additionally, AWS Backup provides automated backup and recovery of Amazon EFS file systems.

When you have an EKS cluster and use the EBS that is local to the node, only Pods running on that node have access to the storage. If the node starts on any other Pod, it will potentially break. There are ways to fix this, but they are beyond this question. I believe we need shared fast storage here, so it should be S3 vs EFS the decision.
