Diverse features and affordability drive effective resource management
Amazon EBS offers diverse features. It can be used for multi-purpose storage, supporting single, multiple, or heavy loads. It has different types for various use cases, allowing me to choose based on my specific requirements. The primary advantage of Amazon EBS is affordability compared to other solutions like EFS or FSX. It acts as a hard drive for servers, making it essential for operation.
MuhammadAzhar Khan - PeerSpot reviewer
Shared storage capabilities provide enterprise value with good reliability
Amazon FSx is more costly compared to other storage solutions like EBS or EFS. The auto-scaling feature should be improved, as it currently includes downtime. I need to manually increase the storage, which is not ideal. Integrating FSx with Windows Server is challenging; it's a long process involving Active Directory (AD) setup and synchronization.

Pros

"The platform is stable and can be replicated across different availability zones and data centers."

Cons

"There is room for improvement in terms of file storage. Recently, we had a scenario in which, in a file share, we had increased the IOPS capacity; this was for the production environment."
"Having more flexibility in resizing, especially scaling down, would be beneficial."
"There are limitations in sharing resources across multiple regions and availability zones. I recommend improving EBS by introducing multi-availability zone support to enhance its functionality."

"A direct FTP feature would be beneficial instead of relying on transmission services."
