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.

From my experience, there are areas in Amazon FSx where more performance is needed, as they will be looking for higher IOPS. Sometimes we go with Weka or other solutions due to this need, so it should have more IO capacity when there is a demand. More performance is needed specifically in the IO area.

Valuable Features

Amazon FSx offers valuable features for disaster recovery, shared storage across enterprise environments, and scalability. Its independent operation eliminates dependencies, and the cloud provider manages backups and administrative tasks. Medium and large enterprises find it beneficial for data sharing. FSx is suitable for high-performance computing with high IO needs, and it performs well for native requirements. Although there may be alternatives like Weka, FSx remains a strong choice for its primary features.

"On a scale of one to ten, I would rate Amazon FSx a ten."
"I rate the stability of Amazon FSx ten out of ten."
"The shared storage capability is highly valuable."

Room for Improvement

AWS console's refresh lag during FSx failovers and inadequate sync mirroring are noted. Users highlight insufficient FSx documentation and training similar to other AWS tools. Costs are higher than alternatives like EBS or EFS, and auto-scaling involves downtime. Integrating with Windows Server is cumbersome. Improved IO performance is necessary as users occasionally opt for other solutions due to higher IOPS demands. Direct FTP features could enhance effectiveness by bypassing transmission services.

Pricing

"The lowest price I have paid is $370 or $380 per month, while the highest can exceed $3,000 per month."

Popular Use Cases

Amazon FSx is primarily utilized for databases requiring failover and recovery support, shared storage for Windows servers, and transferring on-premises shared folders to cloud-based storage. It is favored by life science and pharmaceutical industries, focusing on high-performance computing. Customers often aim to store data on S3 using FSx. It serves small to medium businesses needing robust shared resources, ensuring reliable disaster recovery and cloud integration within AWS environments.

Deployment

Users found Amazon FSx's initial setup straightforward, rating it high. It supports seamless data integration, taking around five to seven minutes for deployment. However, they highlight limitations in switchover support and seek improvements for active-active mode efficiency. Failover works well but requires a page refresh for synchronization update. Active Directory integration poses some challenges. They predominantly use Amazon FSx for cloud-based migrations in hybrid environments, finding its performance comparable to Oracle and MySQL in disaster recovery scenarios.

Scalability

Amazon FSx exhibits high scalability, earning ratings of eight to ten from users. Teams working globally appreciate its flexibility, supporting dynamic mounting and closure. Planning is crucial to leverage full scalability, with primary concerns centered on server capacity rather than storage.

Stability

Amazon FSx shows strong reliability. Users mention occasional interface refresh delays, particularly in AWS Console, leading to accessibility concerns during changes. Despite these delays, a high-rated stability experience is reported, affected by configuration and high availability setup. Service agreements ensure AWS support responsiveness. Some users rate it as optimal, while others face minimal issues. Stability ratings range from eight to ten out of ten.
