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

"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."
"EBS is a very crucial tool as it acts like a hard disk on cloud, providing cost savings compared to physical hard disks, and only incurring costs based on actual usage."
"Overall, I rate Amazon EBS (Elastic Block Store) a nine out of ten."
"The product comes with multiple central port installations like gp2 and gp3."
"When it comes to valuable features, ease of use would be number one."
"The most important feature is the volume types in those hundred EDS. For example, if you need a volume with high IOPS, you should choose an io2 or io2 Block Express volume type. The default volume type for EBS is GP3, which is a good balance of performance and price for most workloads."
"I think everything is great."
"Amazon EBS is valuable because it allows you to store data permanently."
"FSx operates as an independent service, not tied to any server, which eliminates dependencies between applications for storage."
"The shared storage capability is highly valuable."
"On a scale of one to ten, I would rate Amazon FSx a ten."
"We used it for disaster recovery perspective behind a number of resources, like batch services and RDS."
"I rate the stability of Amazon FSx ten out of ten."
 

Cons

"Amazon EBS is scalable, but not auto-scaling. I have to manually scale it, especially in Windows instances, which requires downtime."
"I do not have anything in mind for improvement at the moment."
"There is a concept called Snapshot, which is a backup of the entire EBS volume, however, the cost is quite high."
"One of the major issues in the tool arises whenever it handles a large amount of traffic in the system, making it an area where improvements are required."
"If Amazon could add the auto-scaling feature that exists in RDS to the EBS volumes for EC2 or EKS, it 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."
"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."
"The cost of using EBS is high compared to other cloud vendors such as Tencent Cloud or CARI Cloud. Some costs are generated immediately and some are likely to increase."
"From my experience, there are areas in Amazon FSx where more performance is needed, as they will be looking for higher IOPS."
"A direct FTP feature would be beneficial instead of relying on transmission services."
"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."
"I've been facing a challenge when doing a failover from FSx side. AWS console does not refresh within a half hour."
 

Pricing and Cost Advice

"The pricing models may be for general purposes, such as Amazon EBS Provisioned IOPS Volume or Amazon EBS Cold HDD Volumes."
"The solution is reasonably priced."
"The product is low-priced than other solutions."
"On a scale of one to ten, where one is low price, and ten is high, I rate the price a seven."
"It is a cost-effective solution."
"The solution is quite costly."
"You need to pay additional costs for support."
"The cost can vary greatly depending on the use case, ranging from one dollar to over $1200 dollars per month."
"The lowest price I have paid is $370 or $380 per month, while the highest can exceed $3,000 per month."
