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.
Chetan Jayatheertha - PeerSpot reviewer
Provides valuable features such as access keys, container strings, lifecycle management, audit logs, and the soft delete option
Data Lake Storage provides valuable features such as access keys, container strings, lifecycle management, audit logs, and the soft delete option. These features help in cost-saving and provide an excellent mechanism for backing up data. Furthermore, Data Lake Storage can interact with any other Azure resources, providing seamless integration and connectivity.

Quotes from Members

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

Pros

"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."
"The shared storage capability is highly valuable."
"On a scale of one to ten, I would rate Amazon FSx a ten."
"FSx operates as an independent service, not tied to any server, which eliminates dependencies between applications for storage."
"I would recommend Azure Data Lake Storage because it is straightforward to set up and versatile for various projects, especially AI solutions requiring document storage."
"The tool's most valuable feature is security access policies."
"We can implement one framework and utilize it for multiple use cases."
"The tool offers a big storage layer. The security aspect is quite good. In Azure, there's an option for soft deletes and policy management. This allows us to store only the most up-to-date data while everything else can be policy-managed. This makes handling and management easier."
"The response time and quality offered by the support team are good."
"It's a cloud-based tool within the Microsoft ecosystem, offering many benefits for data handling."
"Azure Data Lake itself doesn't have built-in features for handling data on its own. It's used as a collection of data. Tools you can use with it include Azure Data Factory and Databricks."
"The tool is very safe to use. It is impossible to hack the product."
 

Cons

"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."
"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."
"I've been facing a challenge when doing a failover from FSx side. AWS console does not refresh within a half hour."
"The version was a bit outdated compared to the newer Microsoft Data Fabric offerings."
"When you store your files manually, you can't ensure complete data integrity, which can impact data security."
"Microsoft, in general, needs to simplify its licensing model. That's one of the biggest issues with Microsoft. The licensing model is either quite difficult to understand or is constantly evolving."
"One improvement I'd suggest is the out-of-the-box conversion of input data, like spreadsheet or table data, to various formats. We'll be using Parquet, which enables transactional integrity."
"Microsoft Fabric costs more since we are charged for all the components."
"Improvement is needed in the migration process from Lakehouse to Enterprise Data Lake (EDL). Currently, migration is only one-way possible, and it would be beneficial if this aspect could be improved."
"The high price of the product is an area of concern where improvements are required."
"The solution needs to improve APIs and make them more accessible."
 

Pricing and Cost Advice

"The lowest price I have paid is $370 or $380 per month, while the highest can exceed $3,000 per month."
"Pricing is tricky because it depends on the solution you're building and the type of Data Lake storage you use—hot or cold."
"I rate the product price as two or three, where one is high, and ten is low. The product's price is really high."
"From one to ten, where one is cheap and ten is expensive, I rate the product price as five."
"One of the most affordable products from the vendor"
"It's a pay-as-you-go model. Your charges are based on the amount of data you store."
"The tool's licensing model is pay-as-you-go. Regarding pricing, there's always competition between Azure Data Lake Storage and AWS. They're quite similar, but to attract more customers, Azure Data Lake Storage could consider adjusting its pricing to be more competitive with AWS. This might make Azure Data Lake Storage a more appealing option for users."
"Compared to other options we've explored, I would rate the pricing a seven out of ten, with ten being expensive."
"The tool is cheap, depending on the services and requirements you need."
