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.

Unified data lake has supported daily terabyte workloads and delivers secure automotive analytics
I would rate Azure Data Lake Storage around a nine out of ten. To give Azure Data Lake Storage a ten out of ten, they need to optimize the cost. The cost factor is the only thing I would identify for all my use cases, as they are very well equipped in other areas. Even though the cost is reasonable, if they reduce it, we would benefit significantly. Additionally, there is no data lineage and no ontology tools available on Azure Data Lake Storage. I understand it is blob-based, but if they maintain some ontology tools or data cataloging and data lineage, that would be great. However, those features are currently covered under Databricks, so we are not much concerned.

Quotes from Members

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

Pros

"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."
"Azure Data Lake Storage, if you ask about integration with Azure technology, it is very smooth because the in-house adapters or the connectors are available."
"The tool's most valuable feature is security access policies."
"The tool's best feature is that it can store different types of data - structured, unstructured, and semi-structured—in one lake. We can use the required data for analytics and dashboard design."
"For performance and scalability, we have never faced any issues even though we handle at least a TB of data every day without any performance problems."
"Azure Data Lake Storage is a user-friendly and easy-to-learn solution."
"Microsoft is quite good when it comes to integration. They have multiple connectors available and different ingestion and integration processes available."
"I also like its speed. It's basically built on Azure Blob Storage, which was already fast. But Azure Data Lake Storage adds the hierarchical structure for even better performance."
"Azure Data Lake Storage is user-friendly and easy to use."
 

Cons

"A direct FTP feature would be beneficial instead of relying on transmission services."
"From my experience, there are areas in Amazon FSx where more performance is needed, as they will be looking for higher IOPS."
"I've been facing a challenge when doing a failover from FSx side. AWS console does not refresh within a half hour."
"Amazon FSx is more costly compared to other storage solutions like EBS or EFS."
"The documentation could be more user-friendly with better tutorials."
"There are some gotchas with the pricing; you have to be careful. There's not really a way to throttle it either."
"Simple migrations from one data lake to another take too much time and could be improved."
"Currently, Azure Data Lake Storage has blob, table, and file share, but no vector feature."
"When you store your files manually, you can't ensure complete data integrity, which can impact data security."
"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."
"Azure Data Lake Storage should support other formats apart from the Data Lake format, such as the Iceberg format."
"The version was a bit outdated compared to the newer Microsoft Data Fabric offerings."
 

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."
"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."
"The tool is cheap, depending on the services and requirements you need."
"Pricing is tricky because it depends on the solution you're building and the type of Data Lake storage you use—hot or cold."
"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."
"On a scale from one to ten, where one is cheap and ten is expensive, I rate the solution's pricing a seven out of ten."
"It costs just a few dollars per terabyte per month."
"From one to ten, where one is cheap and ten is expensive, I rate the product price as five."
