Featured Reviews

MuhammadAzhar Khan - PeerSpot reviewer
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.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"EBS is a cost-effective solution, where I pay as I go, making it a favorable option."
"Amazon EBS is a storage system, and the storage is attached to the servers."
"With Amazon EBS, if you want to add an additional disk to an EC2 instance, you can simply attach an EBS volume by clicking through a few options, and it's done."
"The platform is stable and can be replicated across different availability zones and data centers."
"The most valuable feature of the solution stems from the fact that during the deployment, the tool indirectly provides our company with resources for our core side and cloud-based resources."
"The product comes with multiple central port installations like gp2 and gp3."
"The main advantage is the ability to scale up and scale down easily without any downtime."
"Amazon EBS is valuable because it allows you to store data permanently."

"We used it for disaster recovery perspective behind a number of resources, like batch services and RDS."
"On a scale of one to ten, I would rate Amazon FSx a ten."
 

Cons

"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."
"I do not have anything in mind for improvement at the moment."
"It would be good if the solution added a button to increase the size and make the EC2 machine recognize the increased capacity of the EBS."
"Having more flexibility in resizing, especially scaling down, would be beneficial."
"There is a concept called Snapshot, which is a backup of the entire EBS volume, however, the cost is quite high."

"I feel that there are some concerns when it comes to the accessibility area of the product where improvements are required."

"Amazon FSx is more costly compared to other storage solutions like EBS or EFS."
"Amazon FSx is more costly compared to other storage solutions like EBS or EFS."
